An ontological analysis of the UMLS Metathesaurus
نویسندگان
چکیده
Paper-based terminology systems cannot satisfy anymore the new desiderata of healthcare information systems: the demand for re-use and sharing of patient data, their transmission and the need of semantic-based criteria for purposive statistical aggregation. The unambiguous communication of complex and detailed medical concepts is now a crucial feature of medical information systems. Ontologies can support a more effective data and knowledge sharing in medicine. In this paper we briefly survey our ontological analysis and integration of various top-levels of terminologies and we report the main results of the ontological analysis of the UMLS Metathesaurus.

Background & Aim: Unified Medical Language System (UMLS) is an extensive ontology of biomedical knowledge developed and maintained by U.S. National Library of Medicine (NLM). Traditional Iranian Medicine (TIM) does not have any position in the structure of metathesaurus of UMLS. The main aim of this study was designing a scheme of TIM cluster's crotch mapping in the structure of metathesaurus o...

The UMLS is intended to help health professionals and researchers use biomedical information from different sources [2]. The UMLS Metathesaurus is a huge repository of concepts that can be represented as semantic spaces. The UMLS Semantic Network is a limited network of semantic types that “represents knowledge about the biomedical domain, and may be considered a basic ontology for that domain”...
متن کاملConcepts and Synonymy in the UMLS Metathesaurus
This paper advances a detailed exploration of the complex relationships among terms, concepts, and synonymy in the UMLS Metathesaurus, and proposes the study and understanding of the Metathesaurus from a model-theoretic perspective. Initial sections provide the background and motivation for such an approach, and a careful informal treatment of these notions is offered as a context and basis for...
متن کاملEnrichment of French Biomedical Ontologies with UMLS Concepts and Semantic Types for Biomedical Named Entity Recognition Though Ontological Semantic Annotation
Medical terminologies and ontologies are a crucial resource for semantic annotation of biomedical text. In French, there are considerably less resources and tools to use them than in English. Some terminologies from the Unified Medical Language System have been translated but often the identifiers used in the UMLS Metathesaurus, that make its huge integrated value, have been lost during the pro...
متن کاملBattling Scylla and Charybdis: the search for redundancy and ambiguity in the 2001 UMLS metathesaurus
I previously developed methods for identifying cases of multiple synonymous concepts (redundancy) and concepts with multiple meanings (ambiguity) and applied them to the 1995 UMLS Metathesaurus. These methods use semantic approaches (including knowledge about word synonymy and the semantic types assigned to concepts) to complement the standard lexical approaches. In this paper, I describe the r...
