+FB15K-237 Knowledge Base Completion Dataset
+
+This dataset contains knowledge base relation triples and textual mentions of Freebase entity pairs, as used in the work published in [1] and [2]. 
+The knowledge base triples are a subset of the FB15K set [3], originally derived from Freebase. The textual mentions are derived from 200 million sentences from the ClueWeb12 [5] corpus coupled with Freebase entity mention annotations [4].
+
+
+FILE FORMAT DETAILS
+
+The files train.txt, valid.txt, and test.text contain the training, development, and test set knowledge base triples used in both [1] and [2].
+The file text_cvsc.txt contains the textual triples used in [2] and the file text_emnlp.txt contains the textual triples used in [1].
+
+The knowledge base triples contain lines like this:
+
+/m/0grwj	/people/person/profession	/m/05sxg2
+
+The format is:
+
+mid1	relation	mid2
+
+The separator is a tab character; the mids are Freebase ids of entities, and the relation is a single or a two-hop relation from Freebase, where an intermediate complex value type entity has been collapsed out.
+
+The textual mentions files have lines like this:
+
+/m/02qkt        [XXX]:<-nn>:fact:<-pobj>:in:<-prep>:game:<-nsubj>:'s:<ccomp>:pivot:<nsubj>:[YYY]    /m/05sb1    3
+
+This indicates the mids of two Freebase entities, together with a fully lexicalized dependency path between the entities. The last element in the tuple is the number of occurrences of the specified entity pair with the given dependency path in sentences from ClueWeb12.
+The dependency paths are specified as sequences of words (like the word "fact" above) and labeled dependency links (like <nsubj> above). The direction of traversal of a dependency arc is indicated by whether there is a - sign in front of the arc label "e.g." <-nsubj> vs <nsubj>.
