Aggressive morphology for robust lexical coverage
William A. Woods · 2000
This paper describes an approach to providing lexical information for natural language processing in unrestricted domains. A system of approximately 1200 morphological rules is used to extend a core lexicon of 39, 000 words to provide lexical coverage that exceeds that of a lexicon of 80, 000 words or 150, 000 word forms. The morphological system is described, and lexical coverage is evaluated for random words chosen from a previously unanalyzed corpus.
