This paper addresses the issue of word-sense ambiguity in extraction from machine-readable resources for the con- struction of large-scale knowledge sources. We describe two experiments: one which ignored word-sense distinctions, re- sulting in 6.3% accuracy for semantic classification of verbs based on (Levin, 1993); and one which exploited word-sense distinctions, resulting in 97.9% accuracy. These experiments were dual purpose: (1) to validate the central thesis of the work of (Levin, 1993), i.e., that verb semantics and syntactic behavior are predictably related; (2) to demonstrate that a 15-fold improvement can be achieved in deriving semantic information from syntactic cues if we first divide the syntac- tic cues into distinct groupings that correlate with different word senses.
