Towards a Meaning-Full Comparison of Lexical Resources
Kenneth C. Litkowski · 1999
The mapping from WordNet to Hector senses in Senseval provides a "gold standard" against which to judge our ability to compare lexical resources. The "gold standard" is provided through a word overlap analysis (with and without a stop list) for this mapping, achieving at most a 36 percent correct mapping (inflated by 9 percent from "empty" assignments). An alternative componential analysis of the definitions, using syntactic, collocational, and semantic component and relation identification (through the use of defining patterns integrated seamlessly into the parsing dictionary), provides an almost 41 percent correct mapping, with an additional 4 percent by recognizing semantic components not used in the Senseval mapping. Definition sets of the Senseval words from three published dictionaries and Dorr's lexical knowledge base were added to WordNet and the Hector database to examine the nature of the mapping process between definition sets of more and less scope. The techniques described...
