		+	====Question Classification====
		+
		+	Question classification, a question answering subtask, aims to associate a category to each question, typically representing the semantic class of its answer. Question classification is of major importance to QA, since it can help:
		+
		+	* to narrow down the number of possible answer candidates;
		+	* to choose an appropriate answer extraction strategy.
		+
		+	Moreover, a misclassified question can hinder the ability to reach a correct answer, because it can lead to wrong assumptions about the question.
		+
		+	Soon, we will make available the software we used to classify questions, in the source form.

	JWNLSimple is an abstraction layer for JWNL, a WordNet framework with database support. It alsos includes an example SQL script describing a possible conversion of SQL lexicons to the JWNL accepted formalism, allowing procedural queries on WordNet like lexicons. JWNLSimple can be downloaded [http://www.l2f.inesc-id.pt/~pfialho/jwnlsimple/jwnlsimple.zip here] in a jar file also containing a copy of JWNL with some changes described in the [http://www.inesc-id.pt/ficheiros/publicacoes/8113.pdf technical report]. An example SQL lexicon adaptation script can be downloaded [http://www.l2f.inesc-id.pt/~pfialho/jwnlsimple/jwnl_adapt.sql here].
