Question Answering System: Retrieving Relevant Passages

This paper discusses the QA system submitted by Dhirubhai Ambani Institute of Information and Communication Technology, India in the ResPubliQA 2010. We have participated in the monolingual en-en task. Our system retrieves a candidate paragraph that contains the answer to a natural language question. Depending on the n-gram similarity score of the candidate paragraph, a decision is made whether to answer the question or not. The objective of our participation is to test our implementation of various strategies like Query Expansion, n-gram similarity matching, and non-answering criteria.
