Question Classification: A Review of State-of-the-Art Algorithms and Approaches

Abstract

In the recent year Question Answering System achieved significant progress in which Question Classification is an essentialcomponent. To design a question classification that assign a semantic category to a given question that represents the typeof answer required resulting in an accurate Answer. In this paper present various question classification approaches andtechniques, Most of the researches are used to combine Syntactic, Lexical and Semantic features are used to reduce themisclassification. These three techniques are used to improve the efficiency of the question classifications. The existingclassifier lacks in accuracy, especially in fine class classification, from the various existing researches are practiced MachineLearning is the best methodology to evaluate the question classification in an appropriate way.
