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.
