A- NSChunker

NSChunker is combining spaCy, polyglot, and LanguageTool analysers for POS re-disambiguation, high quality chunking, and nominal entities extraction.

NSChunker is a rule-based iterative label rewriter / aggregator. Each rule takes into account the POS-tagging, the extended TAG, and the text of words. Rules are organised in independant layers.

This version is available with rule sets for French and English.

An online demonstrator is available here: http://nschunker.cubaix.com/

1- Install and run spaCy and polyglot servers

NSChunker is using spaCy and polyglot POS-tagger.

  cd SPACY
  bash install.sh
  bash start.sh
  cd ..
  cd POLYGLOT
  bash install.sh
  bash start.sh
  cd ..

2- Install LanguageTool

Get all LanguageTool code and its dependencies.

3- Test NSChunker

Add Java codes in a Java project. Add all LanguageTool code and its dependencies in the classpath. Add json-simple-1.1.1.jar and MindProd-http.jar in the classpath.

Run com.ns.NSChunker.main(). You should get this final chunking:

4- High speed POS-tagging / chunking / nominal entities extraction

• start several copies of spaCy using startN.sh (adapt it according to your number of processors)
• define the number of spaCy servers launched with ClientSpacy.instances = 32;
• create a chunker without polyglot new NSChunker("fr",false)
