Earley parser

A C# implementation of an Earley parser working on Tree-adjoining grammars (working on natural languages)

NLP

The Natural Language examples must use a Part-of-Speech Tagger.

Stanford POS Tagger

Download the Stanford POS Tagger at http://nlp.stanford.edu/software/tagger.html#Download

Make sure it is well referenced in the PosTagger class constructor.

In the examples, make sure you are using the StanfordPosTagger class to generate the ISentence objects.

Talismane

Download Talismane at http://redac.univ-tlse2.fr/applications/talismane.html

Download a language pack like English or French at https://github.com/urieli/talismane/releases

Run Talismane with a command line like: java -Xmx1G -jar talismane-core-2.4.7b.jar languagePack=frenchLanguagePack-2.4.4b.zip command=analyse mode=server encoding=UTF-8 port=7171

In the examples, make sure you are using the Talismane class to generate the ISentence objects.
