JET, the Java Extraction Toolkit, provides a set of tools for constructing information extraction systems: systems for building, from English text, databses which capture specified classes of entities, semantic relations, and events. The tools include sentence and word segmentation, lexicon look-up, name recognition and classification, part-of-speech tagging, chunking, dependency parsing, transformational regularization, within-document coreference resolution. Additional tools are provided to extract entities, relations, and events conforming to the ACE 2005 specification.
