many researches have been conducted on cross-domain recommender systems that combine information from different domains. We propose a method for providing recommendation of books based on TV program information which contains a variety of contents. An important feature in TV domain for extracting books related to a program is different for each program. Furthermore, there are unnecessary programs, such as home shopping, that are not suited for book recommendations because of the environment of cross-domain recommendation. In the proposed method, we use both TF-IDF and LDA methods, which can express programs and books with different abstraction levels, to extract books by weighting and combining these two methods. Moreover, the unnecessary programs are removed and the adequate combining ratio of TF-IDF and LDA methods suited for recommending each program are selected with classification. Our experimental results show that the proposed algorithm using both TF-IDF and LDA methods has higher precision than a method using only TF-IDF. The proposed algorithm also achieves higher precision by removing unnecessary programs and changing the combining ratio according to programs. Additionally, we confirmed that our method can successfully recommend books which interest the research participants corresponding to the programs each participant selected.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2221","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2210","bibliographicIssueDates":{"bibliographicIssueDate":"2016-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"57"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:45:06.245746+00:00","id":175051,"links":{}}
