Abstract: 

MetaMap is a widely available program providing access to the concepts in the UMLS Metathesaurus from biomedical text. MetaMap arose in the context of an effort to improve biomedical text retrieval, specifically retrieval of MEDLINE/PubMed citations. It provided a link between the text of biomedical literature and the knowledge, including synonymy relations, embedded in the Metathesaurus. Early MetaMap development was guided by linguistic principles which provided both a rigorous foundation and a flexible architecture. After some experience with MetaMap, it became clear that it could be applied to tasks other than retrieval, including text mining, classification, question answering, knowledge discovery, and concept-based indexing.
