title: A Completely free nlp parser?
body: <p>So far, I have evaluated few well known Java parsers, but none comes actually free for commercial use, in one way or other. Like OpenNLP, which is free, but uses training data which is not available for commercial purpose. Morphadorner is there, but it seems last updated in 2009. Stanford NLP is full GPL, while LingPipe provides a paid license. </p>
  
  <p>Being an non-funded startup at the moment, it is really not possible for me to pay high license fee.I had to implement a rule based parser for my requirement, which incomparable to industry standard solutions.  </p>
  
  <p>Though, I am not a free-freak and it is not like I need something that only few people in world are using. I firmly believe, things like NLP are getting popularity, and implementing a POS Tagger again is like reinventing a reinvented wheel. Is there really no industry standard solution for this? </p>
  
  <p>Update : The mindset seems industry-standard means a paid thing. Then how come several libraries of HTML parsers(among other stuffs) come free. Html parsers ar far more used than NLP, but still, there is fairly large requirement for NLP tasks.</p>
  
  <p>Update : Question is closed. I shall soon be pleased to release my tiny small library for keyword extraction that makes use of Wordnet and various pretty rules. 
  Thanks
