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.).
