# Buscapé Sample annotated for Semantic Role Labelling
|
105 |
|
106 |
+
The Propbank-Br is a project that aims to annotate corpora with semantic role labels for the purpose of creating training datasets for automated semantic role classifiers. The annotation scheme is quite similar to that of the English Propbank (Palmer et al., 2005), with language-specific differences taken into account. The set of semantic roles was designed to facilitate automatic learning. The annotation is done on syntactic trees generated by the Palavras parser (Bick, 2000).

+
This particular sample was annotated for the purpose of evaluating semantic role classifiers. It contains 840 instances annotated with semantic role labels on syntactic trees generated by the Palavras parser (Bick, 2000). The instances were extracted from the Buscapé corpus (Hartmann et al. 2014), a corpus of user reviews on products. The syntactic trees in the sample were not reviewed by humans, and were annotated using two annotators for each sentence (double-blind annotation).
