> While working on the Dependency Parser/SRL labeler,  we also have a POSTagger from ClearNLP.
 It is fairly simple and I have the code ready (also trained on the same data as the dep parser-
MiPaq/SHARP) to be checked-in.

features.  You can find the reference from this paper.

Linguistics (ACL'12), 363-367, Jeju, Korea, 2012. [1] It also uses AdaGrad for machine learning,
which is a more advanced learning algorithm than maximum entropy used by OpenNLP."
