Subject Re: How to integrate nlp in solr

Aman,

      I feel focusing on  "Question-Answering" and "Information Extraction"
 components of NLP should help you achieve what  you are looking for. Go
through this book *Taming Text * (http://www.manning.com/ingersoll/ ) .
Most of your queries should be answered including details on implementation
and sample source codes.



To state naively :
  NLP tools gives you the power to extract or  interpret knowledge from
text, which you basically store in the lucene index in form of fields or
store along with the terms using payloads. During query processing time,
you similarly gather additional knowledge from the query (using techniques
like query expansion, relevance feedback, or ontologies ) and simply map
those knowledge with the knowledge gained from the text. Its an effort to
move to semantic retrieval rather than simple term matching.

Thanks,
Parnab
