The SPECIALIST Lexical Tools

The SPECIALIST lexical tools are a set of JAVA programs designed to help users manage lexical variation in biomedical text. The tools use information from the SPECIALIST lexicon and other data to generate lexical variants of words or terms appropriate for use in indexing and other NLP applications. The lexical tools are distributed with the UMLS knowledge sources and are used to create and access the normalized word and string indexes to the UMLS Metathesaurus. The lexical tools are open source resources and are freely available subject to these terms and conditions.
