Through the manual analysis of log data of a commercial MMORPG, we identified several numeric features that characterize RMT dealers. We also revealed the significant differences of the volumes of actions and utterances between the roles of RMT dealers. A closed test confirmed the effectiveness of these features on detecting RMT dealers.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告エンタテインメントコンピューティング（EC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-08-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"2010-EC-17"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":70196,"updated":"2025-01-21T23:34:09.187076+00:00","links":{},"created":"2025-01-18T23:29:28.918818+00:00"}
