title: Clustering web page titles on the basis of their meaning
body: <p>I went through this <a href="https://stackoverflow.com/questions/6593030/what-are-some-good-ways-of-estimating-approximate-semantic-similarity-between">link</a>. The code given here could not cluster topics like :</p>
  
  <pre><code>    "Number theory",
      "Finite field",
      "Rational number",
      "Continued fraction representation",
      "Floating point",
      "Mughal architecture"
  </code></pre>
  
  <p>All were in the same cluster.
  What should I do to make the mathematics topics go into one cluster and others into their respective cluster ?</p>
