¬The 1994 Unified Medical Language System Knowledge Sources

Abstract

In 1986 the US National Library of Medicine (NLM) began the Unified Medical Language System (UMLS) project, a long term research and development effort designed to address 2 fundamental barriers to effective biomedical information retrieval: the sheer number of potentially relevant machine readble information sources and the variety of vocabularies and classifications used in these disparate sources. The UMLS strategy involves incremental development and wide deployment of a set of Knowledge Sources designed to assist systems developers in building systems that overcome the problems caused by the number and disparity of databases and vocabularies. Describes the 4 Knowledge Sources contained in the Jun 94 ed.: the Metathesaurus, the Semantic Network, the Information Source Map and the SPECIALIST Lexicon. The hope ist that these Knowledge Sources can reduce the level of effort required to produce more functional informatics application
