This site contains
software
tools, grammars, and examples developed for parsing and
understanding
utterances in natural languages such as English.
Highlights of
the site are:
- ASDEditor, a graphical
editor for directed graphs (networks of nodes linked by directed
edges,
as shown in the small diagram above) called Augmented Syntas
Diagrams
(ASDs), which can be used to represent both grammars and decision networks;
- ASDParser, a tool for
parsing strings of words with ASDs that represent grammars;
- ASDDecider, a tool for
searching ASDs that represent decision networks for values in
unordered
sets of decision variables;
- CardWorld, a testbed
for
building working models of natural-language understanding that
involve
directly-manipulable objects (cards) and collections of objects,
and
one or more modeled CardAgents.
You are free to download and use the tools and examples at
this
site, with appropriate acknowledgment of their origin, and for
those
licensed under the Apache
2.0
license, in compliance with the terms of that
license. The
tools and examples are provided with no warranty expressed or
implied.
Another site
for
ASD examples is http://www.asdgrammars.com That site is maintained by Roxanne Parent. Among
other
things, it provides demonstrations of several ASD tools and
CardWorld
examples that can be run directly from the web site with Java
Web Start.
