BioPortal: A Web Repository for Biomedical Ontologies and Data Resources
Résumé
Biomedical ontologies provide essential domain knowledge to drive data integration, information
retrieval, natural-language processing, and decision support. The National Center for Biomedical
Ontology, one of the seven National Centers for Biomedical Computing created under the NIH
Roadmap, is developing BioPortal, a Web-based system that serves as a repository for
biomedical ontologies. BioPortal defines relationships among those ontologies and between the
ontologies and online data resources such as PubMed, ClinicalTrials.gov, and the Gene
Expression Omnibus (GEO). BioPortal supports not only the technical requirements for access to
biomedical ontologies either via Web browsers or via Web services, but also community-based
participation in the evaluation and evolution of ontology content. BioPortal enables ontology
users to learn what biomedical ontologies exist, what a particular ontology might be good for,
and how individual ontologies relate to one another. The BioPortal system is available online at
the following location: http://bioportal.bioontology.org/.
