Abstract
Question Answering (QA) Systems is an automated approach to retrieve correct responses to the questions asked by human in natural language. The fundamental thought behind QA system is to assist man-machine interaction. In this paper, we propose taxonomy for characterizing Question Answer (QA) systems, briefly survey major QA systems described in literature and provide a qualitative analysis of them. Finally, a comparison between these approaches based on certain features of QA system found critical in our study has been done, in order to bring an insight to research scope in this direction.
