The National Center for Biomedical Ontology Annotator is an ontology-based web service for annotation of textual biomedical data with biomedical ontology concepts. The biomedical community can use the Annotator service to tag datasets automatically with concepts from more than 200 ontologies coming from the two most important set of biomedical ontology & terminology repositories: the UMLS Metathesaurus and NCBO BioPortal. Through annotation (or tagging) of datasets with ontology concepts, unstructured free-text data becomes structured and standardized. Such annotations contribute to create a biomedical semantic web that facilitates translational scientific discoveries by integrating annotated data.
