Link grammars have become the basis for several other research projects. John Lafferty [11] proposes to build and automatically tune a probabilistic language model based on link grammars. The proposed model gracefully encompasses trigrams and grammatical constraints in one framework. Andrew Hunt has developed a new model of the relationship of prosody and syntax based on link grammars. He has implemented the model, and in preliminary tests, the results are much better than with other models. Tom Brehony has modified our parser to detect the kinds of errors that Francophones make when they write in English.
