Researchers in the Stanford Natural Language Processing Group have developed a Java implementation of probabilistic natural language parsers - both lexicalized PCFG parser and highly optimized PCFG and dependency parsers. The parser program provides typed dependencies output as well as phrase structure trees. The software was originally developed for determining the grammatical structure of English sentences and has been adapted to work with other languages, including Chinese, German, Italian and Arabic.
Ongoing Research:The inventors continue to modify and extend the parser to handle other languages, to support additional features, and to improve performance and flexibility.
