Abstract

This paper focuses on extracting question-answer pairs on the Internet which is an useful resource for building Automated Question Answering systems. Question-answer pairs from public resources usually contain noisy information, mostly in the answers. Therefore to obtain reliable question-answer pairs, the answers need to be validated. Previous studies usually handled this problem based on the relationship between a question and its corresponding answers. Differently, this paper proposes a new approach that uses external resources to validate the reliability of answers from question-answer pairs crawled from the Web. We will combine both kinds of information, one is the matching between question and its answers while the other is based on the supporting of external resources to the answers. The experiment conducted on the question-answer pairs extracted from Yahoo!Answer and StackOverflow shows the effectiveness of our proposed method.
