title: How to detect compound words / multiple words as one term.
body: <p>Currently I am trying to detect nouns from texts. 
  I would like to compound words / multiword expressions as one term. 
  For example, I would like to detect "stock market" as one term, rather than "stock" and "market."</p>
  
  <p>If you know any tools, related papers and so on, please let me know. </p>
