The Link Grammar Parser is a syntactic parser of English, based on link
grammar, an original theory of English syntax. Given a sequence of
words, the system assigns to it a syntactic structure, composed of a set
of arcs or "links" of different kinds, connecting pairs of words. The
parser has a dictionary of about 60000 word-forms; it has coverage of a
wide variety of syntactic constructions, many idioms, and capitalization
and punctuation phenomena. It is able to make guesses about the
syntactic categories of unknown words based on context. It is also
robust, and can assign structure to sentences even when it cannot parse
them completely.
The system is written in C, and runs under unix and windows.
Since our last version (version 2.0, in Fall 1995), we have made a
number of improvements to the parser. Its speed is greatly enhanced; its
coverage is significantly improved. We have also incorporated a "panic
mode", which allows the parser to recover some structure on long
sentences in a short amount of time. We have also developed an API for
the system. This allows the parser to be easily integrated into your
own applications.
At the Link Parser website (http://www.link.cs.cmu.edu/link) you can try
the parser out for yourself. This website also contains more
information and detailed documentation of the parser. You are welcome
to download the system from the website and use it for personal or
academic purposes. If you intend to use it for commercial purposes,
please contact us.
We apologize if this is not of interest to you, or if you have
received duplicate copies of this message. We will only be using this
mailing list on rare occasions.
