progress and spread of smartphones and social network services enables us to transmit text messages with GPS location data anywhere and anytime. Since these location-based SNS messages often refer real-world's events, many researchers have tried to recognize real-world's event through analysis of the messages. In this paper, we define a new index of event classification called popularity, and present a novel method to calculate the index by analysing social network of the events participants. Popularity, which reflects the diversity of event participants, is a useful index of the event for creating various applications such as event navigation or recommendation. We designed and implemented intuitive web-based interactive tool for analysing popularity of events. Through comparative experiments by analysis of proposed system and crowdsourcing, we confirmed that our proposal method provide a certain amount of accuracy for calculating the popularity of events.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"82","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"72","bibliographicIssueDates":{"bibliographicIssueDate":"2015-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"56"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:54:28.012330+00:00","id":112726,"links":{}}
