Section Title: introduction Context before the citation: Thus, over the past few years, along with advances in the use of learning and statistical methods for acquisition of full parsers (Collins, 1997; Charniak, 1997a; Charniak, 1997b; Ratnaparkhi, 1997), significant progress has been made on the use of statistical learning methods to recognize shallow parsing patterns syntactic phrases or words that participate in a syntactic relationship (Church, 1988; Ramshaw and Marcus, 1995; Argamon et al., 1998; Cardie and Pierce, 1998; Munoz et al., 1999; Punyakanok and Roth, 2001; Buchholz et al., 1999; Tjong Kim Sang and Buchholz, 2000). While earlier work in this direction concentrated on manual construction of rules, most of the recent work has been motivated by the observation that shallow syntactic information can be extracted using local information by examining the pattern itself, its nearby context and the local part-of-speech information. to ] [NP only $ 1.8 billion ] [PP in ] [NP September] . Citation Sentence: Thus , over the past few years , along with advances in the use of learning and statistical methods for acquisition of full parsers ( Collins , 1997 ; Charniak , 1997a ; Charniak , 1997b ; Ratnaparkhi , 1997 ) , significant progress has been made on the use of statistical learning methods to recognize shallow parsing patterns syntactic phrases or words that participate in a syntactic relationship ( Church , 1988 ; Ramshaw and Marcus , 1995 ; Argamon et al. , 1998 ; Cardie and Pierce , 1998 ; Munoz et al. , 1999 ; Punyakanok and Roth , 2001 ; Buchholz et al. , 1999 ; Tjong Kim Sang and Buchholz , 2000 ) . Context after the citation: Research on shallow parsing was inspired by psycholinguistics arguments (Gee and Grosjean, 1983) that suggest that in many scenarios (e.g., conversational) full parsing is not a realistic strategy for sentence processing and analysis, and was further motivated by several arguments from a natural language engineering viewpoint. First, it has been noted that in many natural language applications it is sufficient to use shallow parsing information; information such as noun phrases (NPs) and other syntactic sequences have been found useful in many large-scale language processing applications including information extraction and text summarization (Grishman, 1995; Appelt et al., 1993). Second, while training a full parser requires a collection of fully parsed sentences as training corpus, it is possible to train a shallow parser incrementally. If all that is available is a collection of sentences annotated for NPs, it can be used to produce this level of analysis.

PE-dev was used to obtain w* to define the utility model. PE-test was held out for testing the algorithmsâ progress on unseen data. Citation Sentence: This was done by MERT optimization ( Och , 2003 ) towards post-edits under the TER target metric . Context after the citation: Note that the goal of our experi- ments is not to improve SMT performance over any algorithm that has access to full information to compute w*. Rather, we want to show that learning from weak feedback leads to convergence in regret with respect to the optimal model, albeit at a slower rate than learning from strong feedback. The feedback data in this experiment were generated by searching the n-best list for translations that are Î±-informative at Î± E 10.1, 0.5, 1.01 (with possible non-zero slack).

It is not aimed at handling dependencies, which require heavy use of lexical information (Hindle and Rooth, 1993, for PP attachment). The presented method concerns primarily with phrases, which can be represented by a tree structure. Citation Sentence: As ( Daelemans et al. , 1999 ) show , lexical information improves on NP and VP chunking as well . Context after the citation: Since our method uses raw data, representing lexical entries will require a lot of memory. In a future work, we plan to use the system for providing instance candidates, and disambiguate them using an algorithm more suitable for handling lexical information. An additional possibility is to use word-types, such as a special tag for be-verbs, or for prepositions like 'of' which attaches mainly to nouns (Sekine and Grishman, 1995). In a similar vain to Skut and Brants (1998) and Buchholz et al. (1999), the method extends an existing flat shallow-parsing method to handle composite structures.

Section Title: introduction Context before the citation: Some previous works (Bannard and Callison-Burch, 2005; Zhao et al., 2009; Kouylekov et al., 2009) indicate, as main limitations of the mentioned resources, their limited coverage, their low precision, and the fact that they are mostly suitable to capture relations mainly between single words. As emerges from the ablation tests reported in (Bentivogli et al., 2010), even the most common resources proved to have a positive impact on some systems and a negative impact on others. Despite the consensus on the usefulness of lexical knowledge for textual inference, determining the actual impact of these resources is not straightforward, as they always represent one component in complex architectures that may use them in different ways. Citation Sentence: Some previous works ( Bannard and Callison-Burch , 2005 ; Zhao et al. , 2009 ; Kouylekov et al. , 2009 ) indicate , as main limitations of the mentioned resources , their limited coverage , their low precision , and the fact that they are mostly suitable to capture relations mainly between single words . Context after the citation: Addressing CLTE we have to face additional and more problematic issues related to: i) the stronger need of lexical knowledge, and ii) the limited availability of multilingual lexical resources. As regards the first issue, itâs worth noting that in the monolingual scenario simple âbag of wordsâ (or âbag of ngramsâ) approaches are per se sufficient to achieve results above baseline. In contrast, their application in the cross-lingual setting is not a viable solution due to the impossibility to perform direct lexical matches between texts and hypotheses in different languages. This situation makes the availability of multilingual lexical knowledge a necessary condition to bridge the language gap.

Section Title: related work Context before the citation: Nugget F-score has been employed as a metric in the TREC question-answering track since 2003, to evaluate so-called definition and âotherâ questions (Voorhees 2003). Recently, there is a growing consensus that an evaluation methodology based on the notion of âinformation nuggetsâ may provide an appropriate framework for assessing the quality of answers to complex questions. In Sections 9 and 10, we have discussed many of these issues. Citation Sentence: Nugget F-score has been employed as a metric in the TREC question-answering track since 2003 , to evaluate so-called definition and `` other '' questions ( Voorhees 2003 ) . Context after the citation: A number of studies (e.g., Hildebrandt, Katz, and Lin 2004) have pointed out shortcomings of the original nugget scoring model, although a number of these issues have been recently addressed (Lin and Demner-Fushman 2005a, 2006b). However, adaptation of the nugget evaluation methodology to a domain as specific as clinical medicine is an endeavor that has yet to be undertaken.

Section Title: conclusion Context before the citation: Regarding future work, there are many research line that may be followed: i) Capturing more features by employing external knowledge such as ontological, lexical resource or WordNet-based features (Basili et al., 2005a; Basili et al., 2005b; Bloehdorn et al., 2006; Bloehdorn and Moschitti, 2007) or shallow semantic trees, (Giuglea and Moschitti, 2004; Giuglea and Moschitti, 2006; Moschitti and Bejan, 2004; Moschitti et al., 2007; Moschitti, 2008; Moschitti et al., 2008). Our novel composite kernels, which account for the two syntactic structures, are experimented with the appropriate convolution kernels and show significant improvement with respect to the state-ofthe-art in RE. For the design of automatic relation classifiers, we have investigated the impact of dependency structures to the RE task.

Context after the citation: ii) Design a new tree-based structures, which combines the information of both constituent and dependency parses. From dependency trees we can extract more precise but also more sparse relationships (which may cause overfit). From constituent trees, we can extract subtrees constituted by non-terminal symbols (grammar symbols), which provide a better generalization (with a risk of underfitting). iii) Design a new kernel which can integrate the advantages of the constituent and dependency tree.

Section Title: related work Context before the citation: In addition, there has been much work on the application of linguistic and semantic knowledge to information retrieval; see Lin and Demner-Fushman (2006a) for a brief overview. For an overview of systems designed to answer open-domain factoid questions, the TREC QA track overview papers are a good place to start (Voorhees and Tice 1999). In this section, however, we will attempt to draw connections to other clinical information systems (although not necessarily for question answering) and related domain-specific question-answering systems. Citation Sentence: In addition , there has been much work on the application of linguistic and semantic knowledge to information retrieval ; see Lin and Demner-Fushman ( 2006a ) for a brief overview . Context after the citation: The idea that clinical information systems should be sensitive to the practice of evidence-based medicine is not new. Based on analyses of 4,000 MEDLINE citations, MendoncÂ¸a and Cimino (2001) have studied MeSH terms associated with the four basic clinical tasks of therapy, diagnosis, prognosis, and etiology. The goal was to automatically classify citations for task-specific retrieval, similar in spirit to the Hedges Project (Haynes et al. 1994; Wilczynski, McKibbon, and Haynes 2001). Cimino and MendoncÂ¸a reported good performance for etiology, diagnosis, and in particular therapy, but not prognosis.

Citation Sentence: However , Dunning ( 1993 ) claims that the log-likelihood chisquared statistic ( G2 ) is more appropriate for corpus-based NLP . Context after the citation: In Section 6, we compare the two statistics in a task-based evaluation. For Table 2, the value of G2 is 3.8 and the value of X2 is 2.5. Assuming a level of significance of a = 0.05, the critical value is 12.6 (for 6 degrees of freedom). Thus, for this a value, the null hypothesis would not be rejected for either statistic, and the conclusion would be that there is no reason to suppose p(runl (canine), subj) is not a reasonable approximation of p(rtml (dog), subj).

Roughly, the E step guesses hidden information: if (xi, yi) was generated from the current fÎ¸, which FST paths stand a chance of having been the path used? (Guessing the path also guesses the exact input and output.) The M step updates 0 to make those paths more likely.

The outcomes of these classifiers are then combined in a way that satisfies some constraints â non-overlapping constraints in this case â using an efficient constraint satisfaction mechanism that makes use of the confidence in the classifierâs outcomes.

Section Title: experiments Context before the citation: A more detailed discussion of the various available Arabic tag sets can be found in Habash (2010). These tag sets are hybrids in the sense that they are neither simply the core POS, nor the complete morphologically enriched tag set, but instead they selectively enrich the core POS tag set with only certain morphological features. Therefore, researchers have proposed tag sets for MSA whose size is similar to that of the English PTB tag set, as this has proven to be a useful size computationally.

Section Title: introduction Context before the citation: But while Bod's estimator obtains state-of-the-art results on the WSJ, comparable to Charniak (2000) and Collins (2000), Bonnema et al.'s estimator performs worse and is comparable to Collins (1996). We show that these PCFG-reductions result in a 60 times speedup in processing time w.r.t. Bod (2001, 2003). This paper presents the first published results with Goodman's PCFG-reductions of both Bonnema et al.'s (1999) and Bod's (2001) estimators on the WSJ. Citation Sentence: But while Bod 's estimator obtains state-of-the-art results on the WSJ , comparable to Charniak ( 2000 ) and Collins ( 2000 ) , Bonnema et al. 's estimator performs worse and is comparable to Collins ( 1996 ) . Context after the citation: In the second part of this paper, we extend our experiments with a new notion of the best parse tree. Most previous notions of best parse tree in DOP1 were based on a probabilistic metric, with Bod (2000b) as a notable exception, who used a simplicity metric based on the shortest derivation. We show that a combination of a probabilistic and a simplicity metric, which chooses the simplest parse from the n likeliest parses, outperforms the use of these metrics alone.

Section Title: experiments Context before the citation: The resulting speech understanding system is called the Voice Natural Language Computer with Expectation (VNLCE, Fink 1983). The expectation system provided the intermediate processing between the errorful output of the speech recognizer and the deep semantics of NLC. An off-the-shelf speech recognition device, a Nippon Electric Corporation DP-200, was added to an existing natural language processing system, the Natural Language Computer (NLC) (Ballard 1979, Biermann and Ballard 1980). Citation Sentence: The resulting speech understanding system is called the Voice Natural Language Computer with Expectation ( VNLCE , Fink 1983 ) . Context after the citation: [The current system should be distinguished from an earlier voice system (VNLC, Biermann et al. 1985), which had no expectation and which handled discrete speech where a 300 millisecond pause must follow each word.] It should be emphasized, of course, that the central issue here is the study of expectation mechanisms and the details of the design decisions could have been made in rather different ways. Thus one could have implemented expectation error correction with a typed input system or with a speech input system that integrates voice signal processing with higher level functions in a way not possible with a commercial recognizer. This implementation shows only one way in which the functions P, Predicts, Mergeable, and Merge can be constructed to achieve expectation capabilities.

Section Title: introduction Context before the citation: In our previous papers (Zhang and Clark 2011; Zhang, Blackwood, and Clark 2012), we applied a set of beams to this structure, which makes it similar to the data structure used for phrase-based MT decoding (Koehn 2010). Second, although we use the term chart, the structure for accepted hypotheses is not a dynamic programming chart in the same way as for the parsing problem. First, the parsing problem has a fixed word order and is considerably simpler than the word ordering problem we are tackling. Citation Sentence: In our previous papers ( Zhang and Clark 2011 ; Zhang , Blackwood , and Clark 2012 ) , we applied a set of beams to this structure , which makes it similar to the data structure used for phrase-based MT decoding ( Koehn 2010 ) . Context after the citation: However, we will show later that this structure is unnecessary when the model has more discriminative power, and a conceptually simpler single beam can be used. We will also investigate the possibility of applying dynamic-programming-style pruning to the chart. We now give an overview of the training algorithm, which is crucial to both the speed and accuracy of the resulting decoder. CCGBank (Hockenmaier and Steedman 2007) is used to train the model.

Citation Sentence: A number of speech understanding systems have been developed during the past fifteen years ( Barnett et al. 1980 , Dixon and Martin 1979 , Erman et al. 1980 , Haton and Pierrel 1976 , Lea 1980 , Lowerre and Reddy 1980 , Medress 1980 , Reddy 1976 , Walker 1978 , and Wolf and Woods 1980 ) . Context after the citation: Most of these efforts concentrated on the interaction between low level information sources from a speech recognizer and a natural language processor to discover the meaning of an input sentence. While some of these systems did exhibit expectation capabilities at the sentence level, none acquired dialogues of the kind described here for the sake of dialogue level expectation and error correction. A detailed description of the kinds of expectation mechanisms appearing in these systems appears in Fink (1983). The problem of handling ill-formed input has been studied by Carbonell and Hayes (1983), Granger (1983), Jensen et al. (1983), Kwasny and Sondheimer (1981), Riesbeck and Schank (1976), Thompson (1980), Weischedel and Black (1980), and Weischedel and Sondheimer (1983).

Section Title: introduction Context before the citation: Another line of research approaches grounded language knowledge by augmenting distributional approaches of word meaning with perceptual information (Andrews et al., 2009; Steyvers, 2010; Feng and Lapata, 2010b; Bruni et al., 2011; Silberer and Lapata, 2012; Johns and Jones, 2012; Bruni et al., 2012a; Bruni et al., 2012b; Silberer et al., 2013). Some efforts have tackled tasks such as automatic image caption generation (Feng and Lapata, 2010a; Ordonez et al., 2011), text illustration (Joshi et al., 2006), or automatic location identification of Twitter users (Eisenstein et al., 2010; Wing and Baldridge, 2011; Roller et al., 2012). Others provide automatic mappings of natural language instructions to executable actions, such as interpreting navigation directions (Chen and Mooney, 2011) or robot commands (Tellex et al., 2011; Matuszek et al., 2012). Citation Sentence: Another line of research approaches grounded language knowledge by augmenting distributional approaches of word meaning with perceptual information ( Andrews et al. , 2009 ; Steyvers , 2010 ; Feng and Lapata , 2010b ; Bruni et al. , 2011 ; Silberer and Lapata , 2012 ; Johns and Jones , 2012 ; Bruni et al. , 2012a ; Bruni et al. , 2012b ; Silberer et al. , 2013 ) . Context after the citation: Although these approaches have differed in model definition, the general goal in this line of research has been to enhance word meaning with perceptual information in order to address one of the most common criticisms of distributional semantics: that the âmeaning of words is entirely given by other wordsâ (Bruni et al., 2012b). In this paper, we explore various ways to integrate new perceptual information through novel computational modeling of this grounded knowledge into a multimodal distributional model of word meaning. The model we rely on was originally developed by Andrews et al. (2009) and is based on a generalization of Latent Dirichlet Allocation.

Section Title: introduction Context before the citation: In particular, since we treat each individual speech within a debate as a single âdocumentâ, we are considering a version of document-level sentiment-polarity classification, namely, automatically distinguishing between positive and negative documents (Das and Chen, 2001; Pang et al., 2002; Turney, 2002; Dave et al., 2003). Task properties Determining whether or not a speaker supports a proposal falls within the realm of sentiment analysis, an extremely active research area devoted to the computational treatment of subjective or opinion-oriented language (early work includes Wiebe and Rapaport (1988), Hearst (1992), Sack (1994), and Wiebe (1994); see Esuli (2006) for an active bibliography). Note that from an experimental point of view, this is a very convenient problem to work with because we can automatically determine ground truth (and thus avoid the need for manual annotation) simply by consulting publicly available voting records. Citation Sentence: In particular , since we treat each individual speech within a debate as a single `` document '' , we are considering a version of document-level sentiment-polarity classification , namely , automatically distinguishing between positive and negative documents ( Das and Chen , 2001 ; Pang et al. , 2002 ; Turney , 2002 ; Dave et al. , 2003 ) . Context after the citation: Most sentiment-polarity classifiers proposed in the recent literature categorize each document independently. A few others incorporate various measures of inter-document similarity between the texts to be labeled (Agarwal and Bhattacharyya, 2005; Pang and Lee, 2005; Goldberg and Zhu, 2006). Many interesting opinion-oriented documents, however, can be linked through certain relationships that occur in the context of evaluative discussions. For example, we may find textual4 evidence of a high likelihood of agreement be4Because we are most interested in techniques applicable across domains, we restrict consideration to NLP aspects of the problem, ignoring external problem-specific information.

Section Title: method Context before the citation: A number of alignment techniques have been proposed, varying from statistical methods (Brown et al., 1991; Gale and Church, 1991) to lexical methods (Kay and Roscheisen, 1993; Chen, 1993). Aligning English-Chinese parallel texts is already very difficult because of the great differences in the syntactic structures and writing systems of the two languages. Some are highly parallel and easy to align while others can be very noisy. Citation Sentence: A number of alignment techniques have been proposed , varying from statistical methods ( Brown et al. , 1991 ; Gale and Church , 1991 ) to lexical methods ( Kay and Roscheisen , 1993 ; Chen , 1993 ) . Context after the citation: The method we adopted is that of Simard et al. (1992). Because it considers both length similarity and cognateness as alignment criteria, the method is more robust and better able to deal with noise than pure length-based methods. Cognates are identical sequences of characters in corresponding words in two languages. They are commonly found in English and French.

Most prominent among these are the rich grammatical subcategorisations of the 60,000 entries, the large amount of information concerning phrasal verbs, noun compounds and idioms, the individual subject, collocational and semantic codes for the entries and the consistent use of a controlled 'core' vocabulary in defining the words throughout the dictionary. We chose to employ LDOCE as the machine readable source to aid the development of a substantial lexicon because this dictionary has several properties which make it uniquely appropriate for use as the core knowledge base of a natural language processing system. Citation Sentence: ( Michiels ( 1982 ) contains further description and discussion of LDOCE . ) Context after the citation: In this paper we focus on the exploitation of the LDOCE grammar coding system; Alshawi et al. (1985) and Alshawi (1987) describe further research in Cambridge utilising different types of information available in LDOCE. The information available in the dictionary is both very rich and diverse, but also typically only semiformalised, as it is intended for human, rather than machine, interpetation. As a consequence the programs we are developing, both to restructure and to exploit this information, need to undergo constant revision as they are being used. The system we describe is not intended for off-line use, where one might attempt to derive, completely automatically, a lexicon for natural language analysis.

Context after the citation: However, given that verbs are not a closed class, in our approach we do not mark chunks beginning with a verb with any marker category. Instead, we take advantage of the fact that the initial phrasal chunks correspond to rule right-hand sides. That is, for a rule in the Penn Treebank VP â> VBG, NP, PP, we are certain (if the annotators have done their job correctly) that the first word in each of the strings corresponding to this right-hand side is a VBG, that is, a present participle. Given this information, in such cases we tag such words with the <LEX> tag.

Section Title: conclusion Context before the citation: There has been some controversy, at least for simple stemmers (Lovins, 1968; Porter, 1980), about the effectiveness of morphological analysis for document retrieval (Harman, 1991; Krovetz, 1993; Hull, 1996). Citation Sentence: There has been some controversy , at least for simple stemmers ( Lovins , 1968 ; Porter , 1980 ) , about the effectiveness of morphological analysis for document retrieval ( Harman , 1991 ; Krovetz , 1993 ; Hull , 1996 ) . Context after the citation: The key for quality improvement seems to be rooted mainly in the presence or absence of some form of dictionary. Empirical evidence has been brought forward that inflectional and/or derivational stemmers augmented by dictionaries indeed perform substantially better than those without access to such lexical repositories (Krovetz, 1993; Kraaij and Pohlmann, 1996; Tzoukermann et al., 1997). This result is particularly valid for natural languages with a rich morphology â both in terms of derivation and (single-word) composition. Document retrieval in these languages suffers from serious performance degradation with the stemmingonly query-term-to-text-word matching paradigm.

Section Title: introduction Context before the citation: We have yet to import such a constraint into our model, but we plan to do so in the near future using the weighted majority algorithm (Littlestone and Warmuth 1992). That is, we want to allocate a larger portion of the probability space to the phrasal and marker lexicons than to the generalized or wordlevel lexicons. We would like to incorporate into our model a procedure whereby translation chunks extracted from the phrasal and marker lexicons are more highly regarded than those constructed by inserting words from the word-level lexicon into generalized marker chunks.

Section Title: related work Context before the citation: Generally speaking, we find that the personal public diary metaphor behind blogs (McNeill, 2005) may bring to an unsatisfactory representation of the context. So we have tested and compared the most used tools available for blogging: Bloggers, WordPress, MovableType and LiveJournal. While wikis have spread from a detailed design (Cunningham and Leuf, 2001), unfortunately blogs have not been designed under a model.

Section Title: None Context before the citation: A number of proposals in the 1990s deliberately limited the extent to which they relied on domain and/or linguistic knowledge and reported promising results in knowledge-poor operational environments (Dagan and Itai 1990, 1991; Lappin and Leass 1994; Nasukawa 1994; Kennedy and Boguraev 1996; Williams, Harvey, and Preston 1996; Baldwin 1997; Mitkov 1996, 1998b). However, the pressing need for the development of robust and inexpensive solutions to meet the demands of practical NLP systems encouraged many researchers to move away from extensive domain and linguistic knowledge and to embark instead upon knowledge-poor anaphora resolution strategies. Much of the earlier work in anaphora resolution heavily exploited domain and linguistic knowledge (Sidner 1979; Carter 1987; Rich and LuperFoy 1988; Carbonell and Brown 1988), which was difficult both to represent and to process, and which required considerable human input. Citation Sentence: A number of proposals in the 1990s deliberately limited the extent to which they relied on domain and/or linguistic knowledge and reported promising results in knowledge-poor operational environments ( Dagan and Itai 1990 , 1991 ; Lappin and Leass 1994 ; Nasukawa 1994 ; Kennedy and Boguraev 1996 ; Williams , Harvey , and Preston 1996 ; Baldwin 1997 ; Mitkov 1996 , 1998b ) . Context after the citation: The drive toward knowledge-poor and robust approaches was further motivated by the emergence of cheaper and more reliable corpus-based NLP tools such as partof-speech taggers and shallow parsers, alongside the increasing availability of corpora and other NLP resources (e.g., ontologies). In fact, the availability of corpora, both raw and annotated with coreferential links, provided a strong impetus to anaphora resolu- tion with regard to both training and evaluation. Corpora (especially when annotated) are an invaluable source not only for empirical research but also for automated learning (e.g., machine learning) methods aiming to develop new rules and approaches; they also provide an important resource for evaluation of the implemented approaches.

In our experiments the translation performances are measured by case-insensitive BLEU4 metric (Papineni et al., 2002) and we use mtevalv13a.pl as the evaluation tool. We train a 4-gram language model on the Xinhua portion of the English Gigaword corpus using the SRILM Toolkits (Stolcke, 2002) with modified Kneser-Ney smoothing (Chen and Goodman, 1998). Citation Sentence: The significance testing is performed by paired bootstrap re-sampling ( Koehn , 2004 ) .

The translation system used for testing the effectiveness of our U-trees is our in-house stringto-tree system (abbreviated as s2t). To create the baseline system, we use the opensource Joshua 4.0 system (Ganitkevitch et al., 2012) to build a hierarchical phrase-based (HPB) system, and a syntax-augmented MT (SAMT) 11 system (Zollmann and Venugopal, 2006) respectively. Citation Sentence: The system is implemented based on ( Galley et al. , 2006 ) and ( Marcu et al. 2006 ) . Context after the citation: In the system, we extract both the minimal GHKM rules (Galley et al., 2004), and the rules of SPMT Model 1 (Galley et al., 2006) with phrases up to length L=5 on the source side. We then obtain the composed rules by composing two or three adjacent minimal rules. To build the above s2t system, we first use the parse tree, which is generated by parsing the English side of the bilingual data with the Berkeley parser (Petrov et al., 2006). Then, we binarize the English parse trees using the head binarization approach (Wang et al., 2007) and use the resulting binary parse trees to build another s2t system.

Section Title: method Context before the citation: Fortunately, indirect associations are usually not difficult to identify, because they tend to be weaker than the direct associations on which they are based (Melamed, 1996c). Models of translational equivalence that are ignorant of indirect associations have "a tendency ... to be confused by collocates" (Dagan et al., 1993). The arrow connecting vk and ukÂ±i in Figure 1 represents an indirect association, since the association between vk and ukÂ±i arises only by virtue of the association between each of them and uk . Citation Sentence: Fortunately , indirect associations are usually not difficult to identify , because they tend to be weaker than the direct associations on which they are based ( Melamed , 1996c ) . Context after the citation: The majority of indirect associations can be filtered out by a simple competition heuristic: Whenever several word tokens ui in one half of the bitext co-occur with a particular word token v in the other half of the bitext, the word that is most likely to be v's translation is the one for which the likelihood L(u, v) of translational equivalence is highest. The competitive linking algorithm implements this heuristic: 1. Discard all likelihood scores for word types deemed unlikely to be mutual translations, i.e. all L(u, v) < 1.

(1976), Grosjean et al. (1979), Dommergues and Grosjean (1983), and Gee and Grosjean (1983), responding to the idea of readjusted syntax as the source of prosodic phrasing, show that grammatical structure, even if readjusted, is not in itself a reliable predictor of prosodic phrasing: mismatches between syntax and prosody occur often and systematically, and can be related to specific nonsyntactic factors such as length and word frequency. Citation Sentence: The psycholinguistic studies of Martin ( 1970 ) , Allen ( 1975 ) , Hillinger et al. ( 1976 ) , Grosjean et al. ( 1979 ) , Dommergues and Grosjean ( 1983 ) , and Gee and Grosjean ( 1983 ) , responding to the idea of readjusted syntax as the source of prosodic phrasing , show that grammatical structure , even if readjusted , is not in itself a reliable predictor of prosodic phrasing : mismatches between syntax and prosody occur often and systematically , and can be related to specific nonsyntactic factors such as length and word frequency . Context after the citation: For example, although prosodic boundaries between subject and verb do occur, there also exist prosodic patterns in which the boundary comes between the verb and object, i.e., the data reveal both X(VY) and (XV)Y groupings. Grosjean et al. (1979) claims that such mismatches are due for the most part to constituent length, which interacts with grammatical structure and, in some cases, overrides it. Thus syntactic and prosodic structure match when the major constituents of a sentence are roughly equal in length; for example, the main prosodic phrase break corresponds to the subject-predicate boundary in Waiters who remember well II serve orders correctly. Discrepancies in length throw constituents off balance, and so prosodic phrasing will cross constituent boundaries in order to give the phrases similar lengths; this is the case in Chickens were eating II the remaining green vegetables, where the subject-predicate boundary finds no prosodic correspondent.4 The most explicit version of this approach is the analysis presented in Gee and Grosjean (1983) (henceforth G&G).

Nugget F-score has been employed as a metric in the TREC question-answering track since 2003, to evaluate so-called definition and âotherâ questions (Voorhees 2003).

Context after the citation: Recently, several alternative, often quite sophisticated approaches to collective classification have been proposed (Neville and Jensen, 2000; Lafferty et al., 2001; Getoor et al., 2002; Taskar et al., 2002; Taskar et al., 2003; Taskar et al., 2004; McCallum and Wellner, 2004). It would be interesting to investigate the application of such methods to our problem. However, we also believe that our approach has important advantages, including conceptual simplicity and the fact that it is based on an underlying optimization problem that is provably and in practice easy to solve.

Section Title: None Context before the citation: The principle of maximum entropy states that when one searches among probability distributions that model the observed data (evidence), the preferred one is the one that maximizes the entropy (a measure of the uncertainty of the model) (Berger et al., 1996). We use a maximum entropy Markov model (MEMM) classifier. We assign to each token in the text a label indicating whether it starts a specific mention, is inside a specific mention, or is outside any mentions. Citation Sentence: The principle of maximum entropy states that when one searches among probability distributions that model the observed data ( evidence ) , the preferred one is the one that maximizes the entropy ( a measure of the uncertainty of the model ) ( Berger et al. , 1996 ) . Context after the citation: One big advantage of this approach is that it can combine arbitrary and diverse types of information in making a classification decision. Our mention detection system predicts the four labels types associated with a mention through a cascade approach. It first predicts the boundary and the main entity type for each mention. Then, it uses the information regarding the type and boundary in different second-stage classifiers to predict the subtype, the mention level, and the mention class.

Section Title: related work Context before the citation: In the context of word alignment, Deng and Byrne (2005) use a state-duration HMM in order to model word-to-phrase translations. The idea of introducing constraints over a model to better guide the learning process has appeared before. Citation Sentence: In the context of word alignment , Deng and Byrne ( 2005 ) use a state-duration HMM in order to model word-to-phrase translations . Context after the citation: The fertility of each source word is implicitly encoded in the durations of the HMM states. Without any restrictions, likelihood prefers to always use longer phrases and the authors try to control this behavior by multiplying every transition probability by a constant ri > 1. This encourages more transitions and hence shorter phrases. For the task of unsupervised dependency parsing, Smith and Eisner (2006) add a constraint of the form âthe average length of dependencies should be Xâ to capture the locality of syntax (at least half of the dependencies are between adjacent words), using a scheme they call structural annealing.

Section Title: related work Context before the citation: With respect to the focus on function words, our reordering model is closely related to the UALIGN system (Hermjakob, 2009). These related models treat their lexical items as latent variables to be estimated from training data, while our model uses a fixed set of lexical items that correspond to the class of function words. Our reordering model is closely related to the model proposed by Zhang and Gildea (2005; 2006; 2007a), with respect to conditioning the reordering predictions on lexical items. Citation Sentence: With respect to the focus on function words , our reordering model is closely related to the UALIGN system ( Hermjakob , 2009 ) .

(2003) suggests that co-training can be helpful for statistical parsing. Another technique for making better use of unlabeled data is cotraining (Blum and Mitchell 1998), in which two sufficiently different learners help each other learn by labeling training data for one another. This approach assumes that there are enough existing labeled data to train the individual parsers. Citation Sentence: The work of Sarkar ( 2001 ) and Steedman , Osborne , et al. ( 2003 ) suggests that co-training can be helpful for statistical parsing . Context after the citation: Pierce and Cardie (2001) have shown, in the context of base noun identification, that combining sample selection and cotraining can be an effective learning framework for large-scale training. Similar approaches are being explored for parsing (Steedman, Hwa, et al. 2003; Hwa et al. 2003).

Section Title: conclusion Context before the citation: We could also introduce new variables, e.g., nonterminal refinements (Matsuzaki et al., 2005), or secondary links Mid (not constrained by TREE/PTREE) that augment the parse with representations of control, binding, etc. (Sleator and Temperley, 1993; Buch-Kromann, 2006). For projective parsing, it is significantly faster than exact dynamic programming, at the cost of small amounts of search error, We are interested in extending these ideas to phrase-structure and lattice parsing, and in trying other higher-order features, such as those used in parse reranking (Charniak and Johnson, 2005; Huang, 2008) and history-based parsing (Nivre and McDonald, 2008). Belief propagation improves non-projective dependency parsing with features that would make exact inference intractable. Citation Sentence: We could also introduce new variables , e.g. , nonterminal refinements ( Matsuzaki et al. , 2005 ) , or secondary links Mid ( not constrained by TREE/PTREE ) that augment the parse with representations of control , binding , etc. ( Sleator and Temperley , 1993 ; Buch-Kromann , 2006 ) . Context after the citation: Other parsing-like problems that could be attacked with BP appear in syntax-based machine translation. Decoding is very expensive with a synchronous grammar composed with an n-gram language model (Chiang, 2007)âbut our footnote 10 suggests that BP might incorporate a language model rapidly. String alignment with synchronous grammars is quite expensive even for simple synchronous formalisms like ITG (Wu, 1997)âbut Duchi et al. (2007) show how to incorporate bipartite matching into max-product BP. Finally, we can take advantage of improvements to BP proposed in the context of other applications.

Section Title: related work Context before the citation: Selectional Preferences have also been a recent focus of researchers investigating the learning of paraphrases and inference rules (Pantel et al., 2007; Roberto et al., 2007). Similarity-smoothed models are simple to compute, potentially adaptable to new domains, and require no manually-compiled resources such as WordNet. Erk (2007) compared a number of techniques for creating similar-word sets and found that both the Jaccard coefficient and Lin (1998a)âs information-theoretic metric work best.

(2007) in using automatically-extracted semantic classes to help characterize plausible arguments. Discriminative techniques are widely used in NLP and have been applied to the related tasks of word prediction and language modeling. Even-Zohar and Roth (2000) use a classifier to predict the most likely word to fill a position in a sentence (in their experiments: a verb) from a set of candidates (sets of verbs), by inspecting the context of the target token (e.g., the presence or absence of a particular nearby word in the sentence).

Section Title: method Context before the citation: Previously LDA has been successfully used to infer unsupervised joint topic distributions over words and feature norms together (Andrews et al., 2009; Silberer and Lapata, 2012). Our experiments are based on the multimodal extension of Latent Dirichlet Allocation developed by Andrews et al. (2009). Citation Sentence: Previously LDA has been successfully used to infer unsupervised joint topic distributions over words and feature norms together ( Andrews et al. , 2009 ; Silberer and Lapata , 2012 ) . Context after the citation: It has also been shown to be useful in joint inference of text with visual attributes obtained using visual classifiers (Silberer et al., 2013). These multimodal LDA models (hereafter, mLDA) have been shown to be qualitatively sensible and highly predictive of several psycholinguistic tasks (Andrews et al., 2009). However, prior work using mLDA is limited to two modalities at a time. In this section, we describe bimodal mLDA and define two methods for extending it to three or more modalities.

If that were the only goal, we could dispense with the feedback mechanism and simply design some sort of discrimination network (or similar device) to test various features of the information being expressed. Citation Sentence: Something like this approach is in fact used in some systems ( e.g. , Elhadad and Robin 1992 ; PenMan 1989 ; Hovy 1988a ) . Context after the citation: The problem with the discrimination network approach is that it can't handle the range of examples shown here without violating the modularity of the generator.

Section Title: experiments Context before the citation: Typical examples are Bulgarian (Simov et al., 2005; Simov and Osenova, 2003), Chinese (Chen et al., 2003), Danish (Kromann, 2003), and Swedish (Nilsson et al., 2005). If we start by considering languages with a labeled attachment score of 85% or higher, they are characterized by high precision and recall for root nodes, typically 95/90, and by a graceful degradation of attachment score as arcs grow longer, typically 95â90â85, for arcs of length 1, 2 and 3â6. before we turn to Swedish and Turkish, focusing on recall and precision of root nodes, as a reflection of global syntactic structure, and on attachment score as a function of arc length. Citation Sentence: Typical examples are Bulgarian ( Simov et al. , 2005 ; Simov and Osenova , 2003 ) , Chinese ( Chen et al. , 2003 ) , Danish ( Kromann , 2003 ) , and Swedish ( Nilsson et al. , 2005 ) . Context after the citation: Japanese (Kawata and Bartels, 2000), despite a very high accuracy, is different in that attachment score drops from 98% to 85%, as we go from length 1 to 2, which may have something to do with the data consisting of transcribed speech with very short utterances. A second observation is that a high proportion of non-projective structures leads to fragmentation in the parser output, reflected in lower precision for roots. This is noticeable for German (Brants et al., 2002) and Portuguese (Afonso et al., 2002), which still have high overall accuracy thanks to very high attachment scores, but much more conspicuous for Czech (BÂ¨ohmovÂ´a et al., 2003), Dutch (van der Beek et al., 2002) and Slovene (DËzeroski et al., 2006), where root precision drops more drastically to about 69%, 71% and 41%, respectively, and root recall is also affected negatively. On the other hand, all three languages behave like high-accuracy languages with respect to attachment score.

This result implies that parsing techniques for HPSG are also beneficial for LTAG 4We eliminated 32 elementary trees because the LTAG parser cannot produce correct derivation trees with them. 5These lexical items are a subset of the original XTAG English grammar distribution.

Section Title: method Context before the citation: â¢ A user study was performed, but it was either very small compared to the corpus (Carmel, Shtalhaim, and Soffer 2000; Jijkoun and de Rijke 2005), or the corpus itself was significantly smaller than ours (Feng et al. 2006; Leuski et al. 2006). â¢ Only an automatic evaluation was performed, which relied on having model responses (Berger and Mittal 2000; Berger et al. 2000). â¢ Only qualitative observations of the responses were reported (no formal evaluation was performed) (Lapalme and Kosseim 2003; Roy and Subramaniam 2006). Citation Sentence: â¢ A user study was performed , but it was either very small compared to the corpus ( Carmel , Shtalhaim , and Soffer 2000 ; Jijkoun and de Rijke 2005 ) , or the corpus itself was significantly smaller than ours ( Feng et al. 2006 ; Leuski et al. 2006 ) . Context after the citation: The representativeness of the sample size was not discussed in any of these studies. There are significant practical difficulties associated with conducting the user studies needed to produce meaningful results for our system. Firstly, the size of our corpus and the number of parameters and settings that we need to test mean that in order for a user study to be representative, a fairly large sample involving several hundreds of requestâresponse pairs would have to be used. Further, user-based evaluations of the output produced by our system require the subjects to read relatively long requestâ response e-mails, which quickly becomes tedious.

Section Title: introduction Context before the citation: Our work on the prosodic phrase status of clause final prepositional phrases, which we discuss below, suggests the existence of a discourse-neutral phrasing that depends on syntactic constituency mediated by string adjacency and length of a potential prosodic phrase.3 Such phrasing provides us with a typical phrasing pattern analogous to the typical phrasal stress patterns examined in Liberman and Prince (1977), which "are often overwhelmed by the chiaroscuro of highlight and background in discourse, but retain the status of null-hypothesis patterns that emerge when Computational Linguistics Volume 16, Number 3, September 1990 157 J. Bachenko and E. Fitzpatrick Discourse-Neutral Prosodic Phrasing in English there is no good reason to take some other option" (p. 251). In other words, when prosodic features that reflect facts of the discourse are removed, is there a residual, neutral phrasing? Thus both of these efforts leave open the question as to whether discourse features completely determine prosodic phrasing or are a complement to some more basic set of determinants, syntactic and/or phonological. Citation Sentence: Our work on the prosodic phrase status of clause final prepositional phrases , which we discuss below , suggests the existence of a discourse-neutral phrasing that depends on syntactic constituency mediated by string adjacency and length of a potential prosodic phrase .3 Such phrasing provides us with a typical phrasing pattern analogous to the typical phrasal stress patterns examined in Liberman and Prince ( 1977 ) , which `` are often overwhelmed by the chiaroscuro of highlight and background in discourse , but retain the status of null-hypothesis patterns that emerge when Computational Linguistics Volume 16 , Number 3 , September 1990 157 J. Bachenko and E. Fitzpatrick Discourse-Neutral Prosodic Phrasing in English there is no good reason to take some other option '' ( p. 251 ) . Context after the citation: This approach to prosodic phrase boundary determination brings us closer to a framework in which phonological, syntactic, and discourse features all contribute to prosodic phrasing. The possibility of a discourse-neutral prosodic phrasing is also of import to the prosodic quality of synthetic speech, since it allows us to "get by" without a complete description of the discourse features of a given text, many of which have yet to be characterized. Interestingly, in the data we examined we found only 14 percent of the phrases to be discourse-determined. The identification of a preferred phrasing that is independent of discourse also aids us in identifying and characterizing the discourse features that impinge on prosodic phrasing.

Section Title: introduction Context before the citation: Another line of research approaches grounded language knowledge by augmenting distributional approaches of word meaning with perceptual information (Andrews et al., 2009; Steyvers, 2010; Feng and Lapata, 2010b; Bruni et al., 2011; Silberer and Lapata, 2012; Johns and Jones, 2012; Bruni et al., 2012a; Bruni et al., 2012b; Silberer et al., 2013). Some efforts have tackled tasks such as automatic image caption generation (Feng and Lapata, 2010a; Ordonez et al., 2011), text illustration (Joshi et al., 2006), or automatic location identification of Twitter users (Eisenstein et al., 2010; Wing and Baldridge, 2011; Roller et al., 2012). Others provide automatic mappings of natural language instructions to executable actions, such as interpreting navigation directions (Chen and Mooney, 2011) or robot commands (Tellex et al., 2011; Matuszek et al., 2012). Citation Sentence: Another line of research approaches grounded language knowledge by augmenting distributional approaches of word meaning with perceptual information ( Andrews et al. , 2009 ; Steyvers , 2010 ; Feng and Lapata , 2010b ; Bruni et al. , 2011 ; Silberer and Lapata , 2012 ; Johns and Jones , 2012 ; Bruni et al. , 2012a ; Bruni et al. , 2012b ; Silberer et al. , 2013 ) . Context after the citation: Although these approaches have differed in model definition, the general goal in this line of research has been to enhance word meaning with perceptual information in order to address one of the most common criticisms of distributional semantics: that the âmeaning of words is entirely given by other wordsâ (Bruni et al., 2012b). In this paper, we explore various ways to integrate new perceptual information through novel computational modeling of this grounded knowledge into a multimodal distributional model of word meaning. The model we rely on was originally developed by Andrews et al. (2009) and is based on a generalization of Latent Dirichlet Allocation.

Context after the citation: We will refer to these models as Likelihood-DOP models, but in this paper we will specifically mean by "Likelihood-DOP" the PCFG-reduction of Bod (2001) given in Section 2.2. In Bod (2000b), an alternative notion for the best parse tree was proposed based on a simplicity criterion: instead of producing the most probable tree, this model produced the tree generated by the shortest derivation with the fewest training subtrees. We will refer to this model as Simplicity-DOP. In case the shortest derivation is not unique, Bod (2000b) proposes to back off to a frequency ordering of the subtrees.

Context after the citation: (Wildly redundant descriptions can result if the âwrongâ preference order are chosen.) We shall see that vague descriptions pose particular challenges to incrementality. One question emerges when the IA is combined with findings on word order and incremental interpretation. If human speakers and/or writers perform CD incrementally, then why are properties not expressed in the same order in which they were selected?

Section Title: introduction Context before the citation: The RenTAL system automatically converts an FB-LTAG grammar into a strongly equivalent HPSG-style grammar (Yoshinaga and Miyao, 2001). This paper describes an approach for sharing resources in various grammar formalisms such as Feature-Based Lexicalized Tree Adjoining Grammar (FB-LTAG1) (Vijay-Shanker, 1987; Vijay-Shanker and Joshi, 1988) and Head-Driven Phrase Structure Grammar (HPSG) (Pollard and Sag, 1994) by a method of grammar conversion. Citation Sentence: The RenTAL system automatically converts an FB-LTAG grammar into a strongly equivalent HPSG-style grammar ( Yoshinaga and Miyao , 2001 ) . Context after the citation: Strong equivalence means that both grammars generate exactly equivalent parse results, and that we can share the LTAG grammars and lexicons in HPSG applications. Our system can reduce considerable workload to develop a huge resource (grammars and lexicons) from scratch. Our concern is, however, not limited to the sharing of grammars and lexicons. Strongly equivalent grammars enable the sharing of ideas developed in each formalism.

Furthermore, we also build MERS models for lexicalized and unlexicalized source trees. Citation Sentence: The features can be easily obtained by modifying the TAT extraction algorithm described in ( Liu et al. , 2006 ) . Context after the citation: When a TAT is extracted from a word-aligned, source-parsed parallel sentence, we just record the contextual features and the features of the sub-trees.

Context after the citation: In a similar way to that of Sarkar and Zeman (2000), Marinov and Hemmingâs system collects both arguments and adjuncts. It then uses the binomial log-likelihood ratio to filter incorrect frames. The BulTreebank trees are annotated with HPSG-typed feature structure information and thus contain more detail than the dependency trees. The work done for Bulgarian is small-scale, however, as Marinov and Hemming are working with a preliminary version of the treebank with 580 sentences.

This system, however, starts with a list of information to be expressed and merely arranges it into a coherent pattern; it is thus not a planner in the sense used here (as Hovy makes clear).

Section Title: related work Context before the citation: Baroni and Bernardini (2004) built a corpus by iteratively searching Google for a small set of seed terms. Turney (2001) extracts word co-occurrence probabilities from unlabelled text collected from a web crawler. Studies have used several different methods to mine web data. Citation Sentence: Baroni and Bernardini ( 2004 ) built a corpus by iteratively searching Google for a small set of seed terms . Context after the citation: Prototypes of Internet search engines for linguists, corpus linguists and lexicographers have been proposed: WebCorp (Kehoe and Renouf, 2002), KWiCFinder (Fletcher, 2004a) and the Linguistâs Search Engine (Kilgarriff, 2003; Resnik and Elkiss, 2003). A key concern in corpus linguistics and related disciplines is verifiability and replicability of the results of studies. Word frequency counts in internet search engines are inconsistent and unreliable (Veronis, 2005). Tools based on static corpora do not suffer from this problem, e.g. BNCweb7, developed at the University of Zurich, and View 8 (Variation in English Words and Phrases, developed at Brigham Young University)	Background	{ "domains": [ "artificial_intelligence" ], "input_context": "multiple_paragraphs", "output_context": "label", "source_type": "single_source", "task_family": "classification" }	acl_arc_intent_classification:train:1062

Section Title: None Context before the citation: Expanding on a suggestion of Michiels (1982), we classify verbs as Subject Equi, Object Equi, Subject Raising or Object Raising for each sense which has a predicate complement code associated with it. In these situations the parser can use the semantic type of the verb to compute this relationship. In any subcategorisation frame which involves a predicate complement there will be a non-transparent relationship between the superficial syntactic form and the underlying logical relations in the sentence. Citation Sentence: Expanding on a suggestion of Michiels ( 1982 ) , we classify verbs as Subject Equi , Object Equi , Subject Raising or Object Raising for each sense which has a predicate complement code associated with it . Context after the citation: These terms, which derive from Transformational Grammar, are used as convenient labels for what we regard as a semantic distinction; the actual output of the program is a specification of the mapping from superficial syntactic form to an underlying logical representation. For example, labelling believe(3) (Type 2 ORaising) indicates that this is a two place predicate and that, if believe(3) occurs with a syntactic direct object, as in (1) John believes the Earth to be round it will function as the logical subject of the predicate complement.

Section Title: introduction Context before the citation: This Principle of Finitism is also assumed by Johnson-Laird (1983), Jackendoff (1983), Kamp (1981), and implicitly or explicitly by almost all researchers in computational linguistics. The issues of control are not so important for us at this point; we restrict ourselves to describing the logic. Therefore these notions, and all other constructs we are going to define (axioms, metarules, definitions etc.) are computational, although usually we will not provide explicit algorithms for computing them. Citation Sentence: This Principle of Finitism is also assumed by Johnson-Laird ( 1983 ) , Jackendoff ( 1983 ) , Kamp ( 1981 ) , and implicitly or explicitly by almost all researchers in computational linguistics . Context after the citation: As a logical postulate it is not very radical; it is possible within a finitary framework to develop that part of mathematics that is used or has potential applications in natural science, such as mathematical analysis (cfXXX Mycielski 1981). On the other hand, a possible obstacle to our strategy of using only finite objects is the fact that the deductive closure of any set of formulas is not finite in standard logic, while, clearly, we will have to deduce new facts from formal representations of text and background knowledge. But there are several ways to avoid this obstruction. For example, consider theories consisting of universal formulas without function symbols.

Section Title: introduction Context before the citation: With the exception of (Fung, 1995b), previous methods for automatically constructing statistical translation models begin by looking at word cooccurrence frequencies in bitexts (Gale & Church, 1991; Kumano & Hirakawa, 1994; Fung, 1995a; Melamed, 1995). 2 Co-occurrence The hidden parameters can be conditioned on prior knowledge about the bitext to improve the model's accuracy. Citation Sentence: With the exception of ( Fung , 1995b ) , previous methods for automatically constructing statistical translation models begin by looking at word cooccurrence frequencies in bitexts ( Gale & Church , 1991 ; Kumano & Hirakawa , 1994 ; Fung , 1995a ; Melamed , 1995 ) . Context after the citation: A bitext comprises a pair of texts in two languages, where each text is a translation of the other. Word co-occurrence can be defined in various ways. The most common way is to divide each half of the bitext into an equal number of segments and to align the segments so that each pair of segments Si and Ti are translations of each other (Gale & Church, 1991; Melamed, 1996a).

Section Title: introduction Context before the citation: Experiments (Section 5) show that forestbased extraction improves BLEU score by over 1 point on a state-of-the-art tree-to-string system (Liu et al., 2006; Mi et al., 2008), which is also 0.5 points better than (and twice as fast as) extracting on 30-best parses. We instead propose a novel approach that extracts rules from packed forests (Section 3), which compactly encodes many more alternatives than kbest lists. also inefficient to extract rules separately from each of these very similar trees (or from the cross-product of k2 similar tree-pairs in tree-to-tree models). Citation Sentence: Experiments ( Section 5 ) show that forestbased extraction improves BLEU score by over 1 point on a state-of-the-art tree-to-string system ( Liu et al. , 2006 ; Mi et al. , 2008 ) , which is also 0.5 points better than ( and twice as fast as ) extracting on 30-best parses . Context after the citation: When combined with our previous orthogonal work on forest-based decoding (Mi et al., 2008), the forest-forest approach achieves a 2.5 BLEU points improvement over the baseline, and even outperforms the hierarchical system of Hiero, one of the best-performing systems to date. Besides tree-to-string systems, our method is also applicable to other paradigms such as the string-totree models (Galley et al., 2006) where the rules are in the reverse order, and easily generalizable to pairs of forests in tree-to-tree models. 2 Tree-based Translation We review in this section the tree-based approach to machine translation (Liu et al., 2006; Huang et al., 2006), and its rule extraction algorithm (Galley et al., 2004; Galley et al., 2006).

Context after the citation: Therefore, the task of relation extraction is most closely related to the tasks addressed in this paper. Researchers have used other notions of semantics in the literature such as latent semantic analysis (Plank and Moschitti, 2013) and relation-specific semantics (Zelenko et al., 2003; Culotta and Sorensen, 2004). To the best of our knowledge, there is only one work that uses frame semantics for relation extraction (Harabagiu et al., 2005). Harabagiu et al. (2005) propose a novel semantic kernel that incorporates frame parse information in the kernel computation that calculates similarity between two dependency trees.

SciRIFF

The SciRIFF dataset includes 137K instruction-following demonstrations for 54 scientific literature understanding tasks. The tasks cover five essential scientific literature categories and span five domains. The dataset is described in our paper SciRIFF: A Resource to Enhance Language Model Instruction-Following over Scientific Literature.

There are three dataset configurations with different max context lengths: 4096, 8192, and 16384. All experiments in the paper are performed with the 4096 context window. You can load the dataset like:

import datasets
ds = datasets.load_dataset("allenai/SciRIFF", "4096")

Code to create the dataset, train models on SciRIFF, and perform evaluation is available at our GitHub repo: https://github.com/allenai/SciRIFF. To train models on SciRIFF data, you should use the SciRIFF train mix dataset.

Task provenance

SciRIFF was created by repurposing existing scientific literature understanding datasets. Below we provide information on the source data for each SciRIFF task, including license information on individual datasets where available. Where possible, we leveraged the BigBIO collection as a starting point, rather than reprocessing datasets from scratch. In the table below, we include the name of the BigBio subset for all tasks available in BigBio; these can be loaded like datasets.load_dataset(bigbio/{bigbio_subset}).
