Virtual machine technologies support hardware-independent application environments on the global IP network allowing a user's “system” to migrate as the user moves from place to place. However, replication of the users' data to all possible destinations is expensive while on demand fetching gives unsatisfactory performance. We propose a semantic data placement method based on the human behaviors specific to the users' network locations. Our algorithm decreases file storage capacity notably while maintaining almost the same prediction accuracy as a more aggressive replication algorithm.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"731","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"724","bibliographicIssueDates":{"bibliographicIssueDate":"2012-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"53"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:35:04.654742+00:00","id":80686,"links":{}}
