| Abstract(in English) | In the field of help-desk business, the need for an accurate QA document retrieval system is intensively increasing. Many QA document retrieval systems have been realized by simply applying conventional full-text search engines designed for general search purposes. But the output of those systems contains not a few "noise" documents less concerned with the content of input query, because they merely treat input query sentences as a set of keywords for search and don't consder with the intentional aspects or semantic content of the sentences. To reduce this noise-jamming problem, we are now developing a new search method that uses phrase-level semantic constraints derived from the input query to select relevant documents to the query. In this paper, we described the search method and the experimental system based on it. |
