Hello,

Thanks. I thought I had an idea for CRF not obtaining good results
with OpenNLP default features, e.g.,

http://lingpipe-blog.com/2006/11/22/why-do-you-hate-crfs/

but if results are also worse in Maxent, that is intriguing. I will
look at the Mallet implementation to see if I find out something.

Re: mallet addon

[Joern Kottmann]

Hello,

I updated the code and afterwards spent some time evaluating it again. The
maxent training is very close to our maxent classifier. I also checked the
training code again and it looks good to me, but it would be nice if you
can review it.

There are a couple of other classifiers in mallet, it should be trivial to
expose them all to OpenNLP.

Hello,

I have seen that there is a mallet addon here

is this currently being used or integrated in opennlp? I have not seen
with the rest of the addons.
