paper addresses a spoken dialogue framework that helps users make decisions. Various decision criteria are involved in selecting from a given set of alternatives. Users often do not have a definite goal or criteria for selection, and thus the system has to bridge the knowledge gap and also recommend an appropriate alternative together with the reason for the recommendation through a dialogue. In this paper, we present a model for such consulting dialogue. In order to evaluate the model, we implement a trial sightseeing guidance system and conduct a user experiment. Then, we optimize the dialogue strategy through reinforcement learning with a natural policy gradient approach using a user simulator trained from the collected dialogue data.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"23","bibliographicVolumeNumber":"2010-SLP-82"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:29:15.935274+00:00","updated":"2025-01-21T23:43:28.188947+00:00"}
