To cope with this problem, we developed a distributed XML query processing scheme which leverages the benefit of lazy evaluation. Our experimental results show up to 22x speedups compared with competitive methods, and demonstrated the importance for distributed XML database systems to take pass-by-reference semantics into consideration.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"115","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"104","bibliographicIssueDates":{"bibliographicIssueDate":"2009-03-31","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":60722,"updated":"2025-01-22T03:01:43.287104+00:00","links":{},"created":"2025-01-18T23:23:05.540531+00:00"}
