Overview of the Biomedical Knowledge Repository (BKR) project. The BKR project integrates data from three primary sources, namely scientific literature in PubMed, structured data in Entrez Gene, and the Unified Medical Language System (UMLS) terminological knowledge source, in RDF format. BKR offers four services using the integrated data namely, (a) enhanced information retrieval (using named relationship as search criteria), (b) multi-document summarization (using the confidence value associated with each assertion for ranking results), (c) question answering (allowing restriction of results to reputable journals or curated databases), and (d) knowledge discovery service using reasoning rules.
