Representing Verbs as Argument Concepts
Table 2: Accuracy of AC, BL and SP concepts
['k', 'Subject AC', 'Subject BL', 'Subject SP', 'Object AC', 'Object BL', 'Object SP']
To quantitatively compare our algorithm to BL and SP, we ask three native English speakers to annotate whether the concepts generated by AC, BL and SP are the correct abstraction of the verb’s arguments. The majority votes are used as the ground truth. AC generates more accurate concepts than BL and SP mainly because AC considers the quality of argument instances extracted from dependency and the semantic overlap between concepts. BL performs worse than SP because the noise caused by parsing error is not considered, but SP considers the association between the verb and arguments which implicitly gives a low rank to the incorrect arguments.
