Abstract
In this paper we report on experiments using WordNet synset tags to
evaluate the semantic properties of the verb classes cataloged by
Levin 1993. This paper represents ongoing research begun at the
University of Pennsylvania (Rosenzweig et al. 1997, Palmer et
al. 1997) and the University of Maryland (Dorr and Jones 1996b, 1996d,
1996e). Using WordNet sense tags to constrain the intersection of
Levin classes, we avoid spurious class intersections introduced by
homonymy and polysemy (_run a bath, run a mile_). By adding class
intersections based on a single shared sense-tagged word, we minimize
the impact of the non-exhaustiveness of Levin's database
(Dorr and Olsen 1996, Dorr to appear). By examining the syntactic
properties of the intersective classes, we provide a clearer picture
of the relationship between WordNet/EuroWordNet and the LCS
interlingua for machine translation and other NLP applications.
