Researchers and analysts are digging deep into the mines of increasing user-generated contents and seeking valuable nuggets of information. However, there is an important but often overlooked factor that must be considered when analyzing social media logs: the existence of the silent majority and the vocal minority. This phenomenon is considered empirical fact within social environments and online media are no exceptions. Without considering the silent majority and the vocal minority, the analysis might reach incorrect conclusions, although the fact that no trace of the silent people shows up on logs complicates analysis. In this paper, we take a model-based approach to uncover the mechanisms behind the silent majority phenomenon with our proposed Vocal-Attitude Propagation Model based on the Linear Threshold Model to analyze the changes in the frequencies of vocal opinions. From our simulation results, we conclude that the influence of high degree agents and independence from local trends are the prominent conditions from which the silent majority and the vocal minority emerge.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1286","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1277","bibliographicIssueDates":{"bibliographicIssueDate":"2017-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"58"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:49:58.086322+00:00","id":182346,"links":{}}
