This object is most useful when used with the RiTaServer as it can take significant time to load the necessary statisical models.

Primarily just a wrapper for the OpenNLP(http://opennlp.sourceforge.net) parser with some minor modifications/simplifications.

For more info see: Berger & Della Pietra's paper: 'A Maximum
Entropy Approach to Natural Language Processing', which
provides a good introduction to the maxent framework.

The full tag set follows:

• S - simple declarative clause, i.e. one that is not introduced by a (possible empty) subordinating conjunction or a wh-word and that does not exhibit subject-verb inversion.
• SBAR - Clause introduced by a (possibly empty) subordinating conjunction.
• SBARQ - Direct question introduced by a wh-word or a wh-phrase. Indirect questions and relative clauses should be bracketed as SBAR, not SBARQ.
• SINV - Inverted declarative sentence, i.e. one in which the subject follows the tensed verb or modal.
• SQ - Inverted yes/no question, or main clause of a wh-question, following the wh-phrase in SBARQ.
• Phrase Level

• ADVP - Adverb Phrase.
• CONJP - Conjunction Phrase.
• FRAG - Fragment.

• LST - List marker. Includes surrounding punctuation.
• NAC - Not a Constituent; used to show the scope of certain prenominal modifiers within an NP.
• NP - Noun Phrase.

• QP - Quantifier Phrase (i.e. complex measure/amount phrase); used within NP.
• RRC - Reduced Relative Clause.
• UCP - Unlike Coordinated Phrase.
• VP - Vereb Phrase.
• WHADJP - Wh-adjective Phrase. Adjectival phrase containing a wh-adverb, as in how hot.
• WHAVP - Wh-adverb Phrase. Introduces a clause with an NP gap. May be null (containing the 0 complementizer) or lexical, containing a wh-adverb such as how or why.
