Title

¬The UMLS project : making the conceptual connection between users and the information they need

Source

Abstract

The goal of the Unified Medical Language System, developed by the National Library of Medicine, is to facilitate the development of conceptual connections between users and relevant databases and to guide users, through their search statements, to the most suitable database for their needs. The UMLS model involves a combination of 4 centrally developed Knowledge Sources (Metathesaurus; Semantic Network; and Information Sources Map), and a variety of smart interface programs that make use of these Knowledge Sources to help users to find computerized information. Current priorities for the UMLS project include developing applications that make use of the Knowledge Sources and using feedback from these applications to guide ongoing enhancement and expansion in the direction of the UMLS project in the development of the Knowledge Sources and in their experimental application
