One that you should try is the BerkeleyParser:<br><a href="http://code.google.com/p/berkeleyparser/">http://code.google.com/p/berkeleyparser/</a><br><br>For a variety of languages, the latent-variable model works better than<br>
head-lexicalized PCFGs.<br>It doesn't require a head table like Bikel's parser, but train/test split<br>is (or was, when I looked) hard-coded, so you still need to go in and tweak<br>some bits.<br><br>Best,<br>Yannick<br>

Dear corpora members,<br>
<br>
I'm looking for tools and trainable constituency parsers for<br>
PCFG's and HPCFG's, preferably ones that support POS input.<br>
I've used Dan Bikel's parser, but was looking for alternatives,<br>
any help would be great.<br>
<br>
Thank you for your time,<br>
Sérgio Castro<br>
