title: Interpreting output from mahout clusterdumper
body: <p>I ran a clustering test on crawled pages (more than 25K docs ; personal data set).
  I've done a clusterdump :</p>
  
  <pre><code>$MAHOUT_HOME/bin/mahout clusterdump --seqFileDir output/clusters-1/ --output clusteranalyze.txt
  </code></pre>
  
  <p>The output after running cluster dumper is shown 25 elements "VL-xxxxx {}" :</p>
  
  <pre><code>VL-24130{n=1312 c=[0:0.017, 10:0.007, 11:0.005, 14:0.017, 31:0.016, 35:0.006, 41:0.010, 43:0.008, 52:0.005, 59:0.010, 68:0.037, 72:0.056, 87:0.028, ... ] r=[0:0.442, 10:0.271, 11:0.198, 14:0.369, 31:0.421, ... ]}
  ...
  VL-24868{n=311 c=[0:0.042, 11:0.016, 17:0.046, 72:0.014, 96:0.044, 118:0.015, 135:0.016, 195:0.017, 318:0.040, 319:0.037, 320:0.036, 330:0.030, ...] ] r=[0:0.740, 11:0.287, 17:0.576, 72:0.239, 96:0.549, 118:0.273, ...]}
  </code></pre>
  
  <p>How to interpret this output? </p>
  
  <p>In short : I am looking for document ids which belong to a particular cluster.</p>
  
  <p>What is the meaning of :</p>
  
  <ul>
  <li>VL-x ?</li>
  <li>n=y c=[z:z', ...]</li>
  <li>r=[z'':z''', ...]</li>
  </ul>
  
  <p>Does 0:0.017 means "0" is the document id which belongs to this cluster? </p>
  
  <p>I already have read on mahout wiki-pages what CL, n, c and r means. But can someone please explain them to me better or points to a resource where it is explained a bit more in detail? </p>
  
  <p>Sorry, if i am asking some stupid questions, but i am a newbie wih apache mahout and using it as part of my course assignment for clustering.</p>
