Task: Question Answering
Input (English): We use two popular knowledge bases: WordNet BIBREF0 and Freebase BIBREF1 in this paper. Specifically, we use WN18 (a subset of WordNet) BIBREF24 and FB15K (a subset of Freebase) BIBREF2 since their text descriptions are easily publicly available. Table 1 lists statistics of the two datasets. 
 Question: What datasets are used to evaluate this paper?
Output (English): WordNet BIBREF0 Freebase BIBREF1 WN18 (a subset of WordNet) BIBREF24  FB15K (a subset of Freebase) BIBREF2
