Development of a semantic type based WSD tool [Abstract].
The Semantic Type Indexing (STI) tool, developed at the National Library of Medicine (NLM), is one of the most accurate unsupervised methods for the word sense disambiguation (WSD) applications. NLM’s Lexical Systems Group (LSG) enhanced the STI tool, achieving an improved precision of 79.05% vs. baseline 73.81% when applied to NLM’s WSD test collection. An ST-based WSD tool, STWSD, has been developed for distribution in the open source Text Categorization (TC) package.
