Furthermore, we investigated the effect of community structures on information diffusion. By the topology information of the detected communities, the number of simulation turns that are sufficient for information to spread over the entire networks indicated that information diffusion speeds strongly depend on the size and the properties of these communities, and that the diffusion strategy by exploiting community structures is more effective and practically executable than the random diffusion strategy.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15029/00000531","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11155514","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Information Sciences, Faculty of Informatics, Department of Information Systems, Undergraduate Student"},{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Information Sciences, Faculty of Informatics, Department of Information Systems"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"東京情報大学総合情報学部情報システム学科(2015年3月卒業)"},{"subitem_text_language":"ja","subitem_text_value":"東京情報大学総合情報学部情報システム学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-30"}],"displaytype":"detail","filename":"KJ00009950579.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","license_note":"TUIS","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00009950579","url":"https://tuis.repo.nii.ac.jp/record/540/files/KJ00009950579.pdf"},"version_id":"ccb58f17-533d-4bb8-acc8-97a0deaf8066"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"コミュニティ抽出","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"二重スターグラフ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"クラスター性","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"情報拡散速度","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"現実","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ネットワーク","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"community detection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"overlapping star-graph","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cluster property","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"information diffusion speed","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"real network","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":"クラスター性によるコミュニティ抽出と情報拡散速度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"クラスター性によるコミュニティ抽出と情報拡散速度","subitem_title_language":"ja"},{"subitem_title":"Community Detection by Clustering Property and Diffusion Speed of Information","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["158"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-09-30"},"publish_date":"2015-09-30","publish_status":"0","recid":"540","relation_version_is_last":true,"title":["クラスター性によるコミュニティ抽出と情報拡散速度"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-12-21T06:29:12.355923+00:00"}
