<p>Question type classification is generally approached like any other text classification problem, thus there is a wide variety of algorithms from simple Naive Bayes to convolutional neural networks that can do this task without additional preprocessing (see for example [this paper]]<a href="http://arxiv.org/pdf/1408.5882v2.pdf" rel="nofollow">1</a> for review of conventional methods for question type classification and <a href="http://arxiv.org/pdf/1408.5882v2.pdf" rel="nofollow">this one</a> for example application of convnets). Perfomance, of course, may vary depending on your task specifics.      </p>
answer type detection in NLP
<p>I have searched so many research papers. but I did not find a good procedure to do this. </p>

<p>how to identify the question type and answer type detection in natural language processing with out using entity recognition?</p>
