Verb-sense Classifier

This system addresses the verb sense disambiguation (VSD) problem, a sub-problem of word sense disambiguation (WSD), for English. It predicts the sense that a verb features in a given sentence, from among other, potential different meanings.

This system was developed as a part of Semantic Role Labeling system.
