Applications
AbiWord, a free word processor, uses Link Grammar for on-the-fly grammar checking. Words that cannot be linked anywhere are underlined in green.
The RelEx semantic relationship extractor, layered on top of the Link Grammar library, generates a dependency grammar output by making explicit the semantic relationships between words in a sentence. Its output can be classified as being at a level between that of SSyntR and DSyntR of Meaning-Text Theory. It also provides framing/grounding, anaphora resolution, head-word identification, lexical chunking, part-of-speech identification, and tagging, including entity, date, money, gender, etc. tagging. It includes a compatibility mode to generate dependency output compatible with the Stanford parser, and Penn TreeBank-compatible POS tagging.
Link Grammar has also been employed for information extraction of biomedical texts and events described in news articles, as well as experimental machine translation systems from English to German and Turkish.
The Link Grammar link dictionary is used to generate and verify the syntactic correctness of two different natural language generation systems: NLGen and NLGen2. It is also used as a part of the NLP pipeline in the OpenCog AI project.
