and efficient retrieval of spatial time series data is indispensable for applications that must provide users with timely and relevant information and services using complex sensor data in the real

This paper introduces an indexing mechanism called I-Tree, which allows for fast retrieval of a massive amount of spatial time-series data, and describes its structure and the search algorithms. We also discuss the results of our performance evaluation using a large amount of artificially-generated spatial time-series data as well as temperature data from micro-weather sensors deployed in a city. I-Tree allows for fast, Euclidean distance-based similarity search of spatial time-series under various conditions.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"39","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"26","bibliographicIssueDates":{"bibliographicIssueDate":"2011-03-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"4"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
