### The CYC® Hierarchy Browser

This page displays a subset of CYC® assertions in indented hierarchical form. The hierarchy is constructed by beginning from a specified starting (or "pivot") term, and recursively following a specified binary relation from the starting term to "superior" and "inferior" terms.

When a starting term is selected and the command to display a hierarchy is given, the upper leftward ("superior") part of the hierarchy is computed first. This part of the hierarchy is then partially compressed in an effort to quickly remove some redundant information, and is displayed. Next the starting term is displayed. Finally, the lower rightward ("inferior") part of the hierarchy is computed and displayed.

### Links from the KB Browser

On several of Cyc's web browser interface pages, certain terms are displayed with a small red diamond to the immediate left of the term. Clicking on this small red diamond will cause a hierarchical display for the term to be constructed.
