This paper shows AR-tree which is a structure of a logical relation etween each set in condition group which composes the definition of the real-space context improve system resource efficiency with reducing the number of compararison condition times to detect a real-space context. Simulation evaluation run in an intended environment that there are an inclusion relation and a crossing relation to other conditions in the condition group to define the real-space context. As the result of evaluation, AR-tree improve system resource efficiency for detection of real-space context compared with R-tree which is one of the most famous.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告システムLSI設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-03-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"49","bibliographicVolumeNumber":"2010-SLDM-144"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":69012,"links":{}}
