interests and actions change as they experience life events such as “childbirth” and “finding employment.” Detecting the topics relevant to users' interests or actions after the life event and extracting the blog posts from those topics make it possible to provide the useful information for life event experience. We propose a method to detect the topics for providing the useful information from blogs posted by users who have experienced life events. First, we estimate the topic distribution in each blog post using dynamic topic models. Second, we filter the topics which co-occurred frequently with other topics in each blog post. Third, we detect the topics by computing the increase in the number of posted users before and after the life event for each topic, and the number of blog posts of which the topic co-occurred with other topics in each blog post. Finally, we present the blog posts with high topic probabilities of the detected topics. We evaluated the proposed method by six research participants who have experienced each life event: “childbirth,” “finding employment,” “marriage,” “university admission,” and “child's admission to elementary school” and compared the proposed method with topic burstiness method. As a result, we confirmed the effectiveness of the proposed method.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"29","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"16","bibliographicIssueDates":{"bibliographicIssueDate":"2018-07-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"11"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-20T01:14:32.555450+00:00","created":"2025-01-19T00:56:20.948517+00:00","links":{},"id":190377}
