Figure 2.

User interface within BioPortal. The figure shows the view seen by a user browsing the NCIT in BioPortal and selecting an ontology concept (in this case, Hepatocellular carcinoma). The user can see the numbers of online resource elements that relate directly to that concept (and the concepts that it subsumes). The interface allows the user to directly access the original elements that are associated with Hepatocellular carcinoma for each of the indexed resources.
