The structures of social media are modeled to clarify the mechanism to participate to social media. We developed a simulation model to clarify the mechanism to participate to social media. In general, there are no systems to punish other users in social media. Instead, there are some systems to rewards other users by comments or replies for communication behaviors. We modeled such reward model by General public goods game to clarify the conditions to realize cooperation dominants situation. From agent-based simulation, it becomes clear that the rewards for the cooperation and the rewards for the rewards can be the factor to encourage the cooperation. Furthermore, we analyzed the relationships between costs and the benefits to encourage the cooperation. From the analysis, the cooperation behaviors become dominant in the case that the benefits for the cooperation and rewards are larger than the cost to reward other users.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2515","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2507","bibliographicIssueDates":{"bibliographicIssueDate":"2012-11-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"11","bibliographicVolumeNumber":"53"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:37:55.920943+00:00","updated":"2025-01-21T17:27:09.753093+00:00"}
