description         Link Grammar Parser

long_description    The Link Grammar Parser is a syntactic parser of English, \
                    based on link grammar, an original theory of English \
                    syntax. Given a sentence, the system assigns to it a \
                    syntactic structure, which consists of a set of labeled \
                    links connecting pairs of words. The parser also produces \
                    a \"constituent\" (Penn tree-bank style phrase tree) \
                    representation of a sentence (showing noun phrases, \
                    verb phrases, etc.).
