The National Center for Biomedical Ontology (NCBO) aims to enhance biomedical science and clinical care through ontology software applications. With partners like Stanford University and Mayo Clinic, NCBO maintains a comprehensive library of biomedical ontologies and develops web services to facilitate their use in research. Key activities include the creation of annotation tools, data access services, and visualization widgets to support scientific communities. Learn about their resources at BioPortal, where researchers can search, comment, and download ontologies for improved data understanding.
