title: WordNet, Query Expansion, Step by Step
body: <p>I want to make a project about query expansion using WordNet,but it's hard to find step by step method to do it.</p>
  
  <p>Based on <a href="http://www.codeproject.com/Articles/11835/WordNet-based-semantic-similarity-measurement" rel="nofollow">this article</a>, I should take the following steps (assuming a sentence as input to the program):</p>
  
  <ol>
  <li>Tokenization</li>
  <li>Tagging part of speech</li>
  <li>Stemming word</li>
  <li>Word sense disambiguation</li>
  <li>Semantic similarity between the two synsets (it still confusing)</li>
  </ol>
  
  <p>...and then we can conclude that the word with larger score is the query expansion from the input. However, I'm still confused about how to perform each of these steps. Is there any source which covers these in more detail?</p>
