Most of sensor data is represented as data streams queried in a real-time manner or a retrospective manner using the stored data streams. Richer query languages over data streams are requierd because of the nature of data streams that is diffrent from that of traditional data. Based on this background, a query language for pattern matching over data streams, called SASE+ was developed [3]. SASE+ is a richer language that contains constructs for expressing the Kleene closure and strategies for selecting relevant data from an input stream mixing relevant and irrelevant data. Since sensor data may be inaccurate because of sensing noise or lack of data, we often apply preprocessing to raw data using a statistical model and so on. Therefore, we focus on query prosessing over preprosessed data streams, particularly probabilistic data streams that are the results of preprosessing using probabilistic model, which are proposed in Markovian Streams [1], [2]. In this paper, we propose a query prosessing method over this probabilistic data stream model using extended SASE+, and also discuss query processing for stored data streams.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_18_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "IEICE Technical Report;DE2012-20", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_18_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/23595"}]}, "item_18_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "一般社団法人電子情報通信学会", "subitem_publisher_language": "ja"}]}, "item_18_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110009626901/", "subitem_relation_type_select": "URI"}}]}, "item_18_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "(c)一般社団法人電子情報通信学会 本文データは学協会の許諾に基づきCiNiiから複製したものである", "subitem_rights_language": "ja"}]}, "item_18_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_18_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0913-5685", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "加藤, 翔", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "62420", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "石川, 佳治", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "62421", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KATO, Sho", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "62422", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "ISHIKAWA, Yoshiharu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "62423", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-21"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "110009626901.pdf", "filesize": [{"value": "934.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 934600.0, "url": {"label": "110009626901.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/21466/files/110009626901.pdf"}, "version_id": "f07351c7-8616-4f94-912b-b1be2c7ea617"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "確率的データストリーム", "subitem_subject_scheme": "Other"}, {"subitem_subject": "SASE+", "subitem_subject_scheme": "Other"}, {"subitem_subject": "NFA^bオートマトン", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Probabilistic data streams", "subitem_subject_scheme": "Other"}, {"subitem_subject": "NFA^b automaton", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "確率的データストリームに対する問合せ処理手法", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "確率的データストリームに対する問合せ処理手法", "subitem_title_language": "ja"}]}, "item_type_id": "18", "owner": "1", "path": ["703"], "permalink_uri": "http://hdl.handle.net/2237/23595", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2016-02-24"}, "publish_date": "2016-02-24", "publish_status": "0", "recid": "21466", "relation": {}, "relation_version_is_last": true, "title": ["確率的データストリームに対する問合せ処理手法"], "weko_shared_id": -1}
