While a popular photo-spot in general means a spatially localized region, it should have its own hot-period, a period of time during which it can provide more interesting photographs than other photo-spots. In this paper, we address the problem of extracting a pair of a major photo-spot and its hot-period, which is called a hot photo-spot, from a large number of geotagged photographs with timestamps that many people have taken. We propose a mathematical model for hot photo-spots, and present a method of efficiently identifying them. Using real Flickr data, we experimentally demonstrate the effectiveness of the proposed method.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告数理モデル化と問題解決（MPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-02-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2012-MPS-87"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":80870,"updated":"2025-01-21T19:36:25.830159+00:00","links":{},"created":"2025-01-18T23:35:13.484432+00:00"}
