Development and Evaluation Support System for
Unification-based Grammars

Prof Yuji Matsumoto, et al., Nara Institute of Science and Technology
[Features of the Software]
The system provides an environment for the development of
natural language grammars by showing the trace of the parsing
process. The system consists of a Chart-based parsing system,
called SAX, that runs with a Definite Clause Grammar by
compiling the given grammar into fast Prolog code. The
developed system, called Tk-VisIPS, shows the intermediate
results of the parsing in a trianglar table like the one used in
the CKY parsing algorithm. It provides the user with facilities
which display parse trees as well as internal representation
of phrases. This makes it easy for the user to identify the cause of
errors in her/his grammar rules and lexical entries.
[Required Environment]
A Unix workstation with XwindowR5, Tcl/Tk (ver4.0), SICStus
Prolog 2.1 (or 3), Perl (4.xx or over).
