Integrating the UMLS into an RDF-Based Biomedical Knowledge Repository.

As part of Advanced Library Services project at the National Library of Medicine, we are creating a very large Biomedical Knowledge Repository (BKR), which serves as background knowledge for applications including knowledge discovery and multidocument summarization [1]. The BKR integrates relations extracted from the biomedical literature (e.g., Medline citations) and from structured knowledge sources (e.g., Entrez Gene). It will also host relations contributed by external collaborators.
