The document discusses the CLEAR dependency format, which adapts the Stanford dependency format. The CLEAR format remaps dependencies for empty categories, preserves function tags, and preserves secondary dependencies. It then provides details on CLEAR dependency labels, remapping empty categories through constructions like wh-movement, function tags for syntactic and semantic roles, and secondary dependencies involving structures like gapping, referents, right node raising, and open clausal subjects.
