What is python-link-grammar
python-link-grammar is:
In Sleator, D. and Temperley, D. “Parsing English with a Link Grammar” (1991), the authors defined a new formal grammatical system called a “link grammar”. A sequence of words is in the language of a link grammar if there is a way to draw “links” between words in such a way that the local requirements of each word are satisfied, the links do not cross, and the words form a connected graph. The authors encoded English grammar into such a system, and wrote this program to parse English using this grammar.
link-grammar can be used for linguistic parsing for information retrieval or extraction from natural language documents. It can also be used as a grammar checker.
This package contains a Python 2 library for using link-grammar.
