This project fits within the research context of the Natural Language Systems Program within the Cognitive Science Branch at the Lister Hill Center for Biomedical Commmunications. The Semantic Knowledge Representation (SKR) project is concerned with reliable and effective management of the information encoded in natural language texts. The project develops programs that provide usable semantic representation of biomedical text by building on resources currently available at the Library, especially the UMLS knowledge sources and the natural language processing tools provided by the SPECIALIST system. Two programs in particular, MetaMap and SemRep, are being evaluated and enhanced and applied to a variety of problems in the management of biomedical information. These include automatic indexing of MEDLINE citations (Indexing Initiative), concept-based query expansion, analysis of complex Metathesaurus strings, accurate identification of the terminology and relationships in anatomical documents, and the extraction of chemical binding relations from biomedical text. Adobe's PDF reader "Acrobat Reader" is required for reading most of the papers: Selecting the following button will take you to Adobe's free Acrobat Reader download web site. |
