Joyce Yue Chai, IBM T.J. Watson Research Center and Alan W. Biermann, Duke University

This paper describes a rule-based methodology for word sense disambiguation and an application of the methdology to information extraction using rules generalized with the held of the WordNet system. The methodology creates word sense disambiguation rules based on user trained examples working in the domain of interest. It achieves accuracy rates comparable to the best competing methods and can be easily integrated into higher level applications.
