A node is defined as a blogger and an edge is a connection of trackback. First, the proposed technique extracts frequent communities by extracting frequent subgraphs. Second, the proposed technique extracts overlapping communities by clustering the extracted subgraphs. In the procedures of extraction of frequent subgraphs, we transform the frequent subgraphs extraction problem to the frequent itemsets extraction problem. In the first step, the LCM algorithm is applied to extract the frequent itemsets. In the second step, we applied the Newman's algorithm to find overlapping clusters. To confirm the availability of proposed technique, we collected the graph data and extracted the frequent communities. As a result, frequent communities which have common interests and the bloggers who are clustered into multiple clusters are extracted.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人情報処理学会"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110006684621","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"CiNii Research"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://cir.nii.ac.jp/crid/1050001337891725696","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"情報処理学会電子図書館"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ipsj.ixsq.nii.ac.jp/ej/?action=pages_view_main&active_action=repository_view_main_item_detail&item_id=17074&item_no=1&page_id=13&block_id=8","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"情報処理学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"},{"subitem_rights":"The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
