The key characteristic of stream data demands a new approach. This paper focuses on the problem to detect exactly similar pairs among multiple data streams with similarity queries of arbitrary length. We propose DAPSS (DAta stream Processing for Store and Search), an efficient method to detect similar streams, which keeps (1) the feature data of each sequence in memory space and (2) the compressed data of the original sequences in disk space. Experiments show DAPSS is significantly faster than the naive method.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"14","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2007-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG7(TOD33)","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
