TY - JOUR T1 - ACQUISITION OF SEMANTIC LEXICONS JF - Breadth and depth of semantic lexicons Y1 - 1999 A1 - Dorr, Bonnie J A1 - Jones,D. AB - This paper addresses the problem oflarge-scale acquisition of computational-semantic lexicons from machine-readable resources. We describe semantic filters designed to reduce the number ofincorrect assignments (i.e., improve precision) made by a purely syntactic technique. We demonstrate that it is possible to use these filters to build broad-coverage lexicons with minimal effort, at a depth of knowledge that lies at the syntax-semantics interface. We report on our results of disambiguating the verbs in the semantic filters by adding WordNet sense annotations. We then show the results of our classification on unknown words and we evaluate these results. VL - 10 ER -
