Question Answering Experiments at NTCIR-5: Acquisition of Answer Evaluation Patterns and Context Processing using Passage Retrieval |
Abstract | ||
---|---|---|
In our participation in QAC3, our Question An- swering system developed for QAC2 is extended in two ways, separately. The first system is constructed to im- prove the performance of answer evaluation. The au- tomatic lexico-syntactic pattern acquisition from large corpora and the method to incorporate the patterns into QA system are developed and evaluated. The second system is constructed to implement the ability of context processing for information access dialogue (IAD), which is a main target ofQAC3 evaluation. The system exploits passage retrieval for selecting an ap- propriate context from the history of the series ques- tions, in order to compose a complete question. |
