<div>Hi,</div>
<div><br clear="all">I have downloaded NLTK recently. I used nltk.ne_chunk() for Named Entity Recognition using maxent multi-class chunker. I am amazed at the output. But I still need to train this further to improve accuracy and more to add domain specific labels.</div>
<div> </div>
<div>I am looking for tutorial / manual to train this multi-class chunker (is possible using an example). </div>
<div>Could anybody please let me know if there is any material / book online for this.</div>
<div> </div>
<div>Thanks,</div>
