PROBLEM TO BE SOLVED: To present appropriate associated information as a response to a query.SOLUTION: A query input unit 210 accepts a query in which a class comprises a combination of three defined elements <entity, attribute, value>. A text search unit 230 searches for text associated with elements included in the accepted query. A text analysis unit analyzes the searched text. A parameter adaption unit 234 obtains a replaced post-adaption parameter on the basis of the query, a feature concerning the class of each of three elements, and a parameter for the feature of each of other words. A text summation unit 236 generates a summary statement about the text on the basis of the text analyzed by the text analysis unit 232 and a post-adaption parameter database 242 obtained by the parameter adaption unit 234. The end-of-sentence expression included in the summary statement is converted to an end-of-sentence expression for expressing a response by an end-of-sentence expression conversion unit 238, and a response output unit 250 outputs the converted summary statement as a response.SELECTED DRAWING: Figure 6 |
