An utterance content estimator estimates a document ID corresponding to an answer to user input analysis results from a document on the basis of an utterance estimating model that is generated by learning a correspondence between hypothetical questions each as to a content of the document and document IDs each of which is an answer to one of the hypothetical questions. A result integrator integrates document estimation results of the utterance estimating model and document search results of search indexes so as to generate final search results. |
