Grok

Grok is a library of Java components for performing various natural language tasks. These include several preprocessing tasks, chart parsing, a large categorial grammar for English (induced from the Penn treebank), and some knowledge representation components (basic coreference, salience tracking, etc.). The library also has a companion kit which provides a GUI interface to the components, several of which are implementations of interfaces in the Quipu OpenNLP API.

    Release Notes: A whole bunch of stuff was cut out of this release. The preprocessing components now use the new XML structure of NLPDocuments appropriately.

      Release Notes: Improvements to the Grokling frontend, resurrection of parsing, updates for changes to unification architecture of OpenNLP, use of XML in preprocessing components conforms with JDOM, many improvements to sentence detection code, and new samples in the source tree.

        Release Notes: A problem in the build.xml file that was causing the maxent models to be corrupted when the grok jar was created was fixed. The infrastructure for creating and releasing the Grok homepage was improved.

        •  16 Oct 2001 17:05

          Release Notes: Improvements were made to the sentence detection code. All maxent models were converted to the new single file format. The part-of-speech tagging model is trained on much more data and uses a number of word stems to avoid some errors. Grok was updated for changes in the OpenNLP API. Grok now uses Ant to build. The directory structure has been changed considerably to facilitate the creation of distribution files, and to ensure that source code and supporting libraries are provided with distributions. Note: The lexicon system is broken in this version, and therefore it cannot be used to parse.
