The experiment focused on the following two questions: 1) What effct does data length have on the processing speed of the optical disk? 2) To what degree does index organization affect data retrieval time? We succeeded in reducing the time necessary for writing Japanese language data(10.21M bytes)on a distributed processor from 325 minutes (4k bytes) to 167 minutes(16k bytes). The results of the experiment suggest we could further reduce the writing time by 50% by making the length of written data accord with the track length of the optical disk.The reading time was also reduced from 900 minutes to 180 minutes by integrating the data management table and data retrieval index. We suggested that in order to make the optical disk work as fast as the magnetic disk device we need to improve the Read-After-Write method, enlarge the data transfer unit on the compiler,and modify the data length on the communication line.", "subitem_description_type": "Other"}]}, "item_10002_description_51": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_10002_description_56": {"attribute_name": "注記", "attribute_value_mlt": [{"subitem_description": "17の書名 : 国立国語研究所研究報告集", "subitem_description_type": "Other"}]}, "item_10002_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15084/00001106", "subitem_identifier_reg_type": "JaLC"}]}, "item_10002_publisher_39": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "国立国語研究所"}]}, "item_10002_relation_57": {"attribute_name": "シリーズ", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "国立国語研究所報告 ; 90"}]}]}, "item_10002_relation_58": {"attribute_name": "シリーズ(英)", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "The National Language Research Institute Research Report ; 90"}]}]}, "item_10002_title_29": {"attribute_name": "タイトル（ヨミ）", "attribute_value_mlt": [{"subitem_title": "ヒカリ ディスク オ シヨウ シタ タイリョウ ニホンゴ データ ノ チクセキ"}]}, "item_10002_version_type_52": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "斎藤, 秀紀"}, {"creatorName": "サイトウ, ヒデノリ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "2760", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SAITO, Hidenori", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "2761", "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": "2017-03-31"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "kkrep_090_04.pdf", "filesize": [{"value": "1.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1500000.0, "url": {"label": "kkrep_090_04.pdf", "url": "https://repository.ninjal.ac.jp/record/1122/files/kkrep_090_04.pdf"}, "version_id": "58a623c8-6555-41a2-b819-22d72af15959"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "情報検索システム", "subitem_subject_scheme": "Other"}, {"subitem_subject": "追記型光ディスク", "subitem_subject_scheme": "Other"}, {"subitem_subject": "大量日本語データ", "subitem_subject_scheme": "Other"}, {"subitem_subject": "分散処理", "subitem_subject_scheme": "Other"}, {"subitem_subject": "information storage and retrieval system", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Write-Once-Read-Many optical disk", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "large-scale Japanese language data", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "distributed processing", "subitem_subject_language": "en", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "光ディスクを使用した大量日本語データの蓄積", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "光ディスクを使用した大量日本語データの蓄積"}, {"subitem_title": "On large-scale Japanese language storage on optical disks", "subitem_title_language": "en"}]}, "item_type_id": "10002", "owner": "3", "path": ["117"], "permalink_uri": "https://doi.org/10.15084/00001106", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-03-31"}, "publish_date": "2017-03-31", "publish_status": "0", "recid": "1122", "relation": {}, "relation_version_is_last": true, "title": ["光ディスクを使用した大量日本語データの蓄積"], "weko_shared_id": -1}
