this paper, we propose a method for accurately retrieving XML elements considering document updates. If document updates are not handled in a search system, users cannot obtain appropriate search results, which reduces the usefulness of the search system. We apply an incremental approach to update an index because a rebuild-from-scratch approach takes longer time. In addition, global weights, i.e., the statistics computed with all documents in the search system, may not be accurate when a few number of documents is indexed or when global weights change drastically. To solve these problems, we propose to extend a function of incremental updates of indices to general XML element retrieval systems, with filters to reduce the update cost by eliminating unimportant elements and terms. Moreover, we apply a method for integrating path expression which estimates accurate global weights in term calculation. Experimental results showed that our proposed method can be up to 25% faster to update indices than the simple incremental updates and can improve the search accuracy by 4% with document set of static statistics. The proposed method can also search accurately, even under continuous changes in the statistics of the documents.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"16","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-09-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"6"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":95325,"updated":"2025-01-21T13:56:03.400845+00:00","links":{},"created":"2025-01-18T23:42:26.706714+00:00"}
