Benchmark 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 set of labeled links connecting pairs of words.

The parser has a dictionary of about 60000 word forms. It has coverage of a wide variety of syntactic constructions, including many rare and idiomatic ones. The parser is robust; it is able to skip over portions of the sentence that it cannot understand, and assign some structure to the rest of the sentence. It is able to handle unknown vocabulary, and make intelligent guesses from context about the syntactic categories of unknown words.


Input Description

The input is a sequence of proposed sentences, one per line. Punctuation and case matter.


Output Description

The output is an analysis of the proposed input sentence. The analysis includes a set of links which capture the grammatical structure of the sentence, a labelling of each word with an appropriate part of speech tag, along with a judgement of the grammaticality of the input sentence. Words in square brackets are ones that the parser deems superfluous.


Programming Language

The parser is written in ANSI C.


Known portability issues

None
