Determining the Plausibility of Answers to Questions

Contents

This paper describes AnswerOK, a system which determines whether the answer to a question is plausible. While not a question-answering system itself, it could be used by question-answering systems to check the plausibility of possible answers found in a large corpus (i.e., the TREC Q/A task). We explain the strategies used by AnswerOK, and present results which suggest that AnswerOK would likely improve the performance of many TREC Q/A systems.
