AV Parser: Unification-based parser.

areas/nlp/parsing/av/
The AV Parser is a ``unification-based'' parser (Shieber 1986) for natural language parsing with ``attribute-value'' based theories of grammar. It is intended for research and instructional purposes and has the following features - graphical user interface, with tree and attribute-value matrix drawing routines, and the graphics can be "cut and paste" into other applications (e.g. word processors), supported by a scrolling-pict-view window class - completely customizable grammar specification language (an LALR(1) parser-generator is included) - several small sample grammars are included The graphics routines and the LALR(1) parser generator may be of independent interest to the MCL community.
