title: how to extract nouns and substantives from a phrase?
body: <p>I would like to extract nouns, substantives and adjectives from a given text phrase. Is there a java library (open source) that does that? Does anyone know how to do that?</p>
  
  <p>Basically, I was thinking in creating separated dictionaries for these categories (nouns, substantives, adjectives) and then parse the phrase, separate words in tokens and compare against these dictionaries but having something (lib) that already does that for me would be great. More perfect if it supports Brazilian Portuguese language!</p>
  
  <p>Thanks.</p>
