Answer Path at NTCIR-7 CCLQA Track

This is the first time that our group participate NTCIR and Answer Path is a brand new system. In this system, we have normally three components as Question Analyzer, Passage Retrieval and Answer Extractor. Question Analyzer used the combination methods of rules and Lucene was the choice of our search engine platform. And in Answer Extraction, we cut the retrieved passage into sentences and utilized Wikipedia resource to sort and evaluate our answers in Biography Question and Definition Question. Other than that, we experimented on clustering method in Event Question, and Relationship Question was treated as the combination of several definition questions. Asides from the main components above, we developed Sentence Resemble Model and Answer Filtering and so on. And there were a lot of components in our plan that would be developed in the future.
