Welcome
Welcome to the National Cancer Institute (NCI) BioPortal. The NCI BioPortal provides access to the NCI Thesaurus, the NCI Metathesaurus and other select and publicly accessible biomedical terminologies hosted at the NCI. The original version of the BioPortal was written by the National Center for Biomedical Ontology (NCBO) and was used as the baseline for development of the NCI version of BioPortal. Much of the code base was reused and modified where appropriate to meet the needs of the National Center Institute Center for BioInformatics (NCICB).
Getting StartedThe NCI BioPortal enables you to browse, search, and visualize terminologies in the library.
Use the BioPortal to browse the library contents, view project details and metadata or view available versions. To Download  , Visualize  , or Search  a specific terminology, select the appropriate icon in the action column.

-
