title: Run cvb in mahout 0.8
body: <p>The current Mahout 0.8-SNAPSHOT includes a Collapsed Variational Bayes (cvb) version for Topic Modeling and removed the Latent Dirichlet Analysis (lda) approach, because cvb can be parallelized way better. Unfortunately there is only documentation for <a href="https://cwiki.apache.org/confluence/display/MAHOUT/Latent+Dirichlet+Allocation">lda</a> on how to run an example and generate meaningful output.</p>
  
  <p>Thus, I want to:</p>
  
  <ul>
  <li>preprocess some texts correctly</li>
  <li>run the cvb0_local version of cvb</li>
  <li>inspect the results by looking at the top n words in each of the generated topics</li>
  </ul>
