          This page describes a set of six parallel corpora obtained by translating popular
          Wikipedia documents in six languages from the Indian sub-continent into English. The
          languages are:

          <ul>
            <li>Bengali</li>
            <li>Hindi</li>
            <li>Malayalam</li>
            <li>Tamil</li>
            <li>Telugu</li>
            <li>Urdu</li>
          </ul>

          <p>
            The collection and release of this data is described in the following paper:
