photographs have been shared on photo-sharing sites, and those are annotated with tags and geo-tags. Some studies have demonstrated extraction of hotspots and a geographical characterization which a tag represents using those metadata. However, in some cases, a line is more suitable than a region as a geographical characterization (e.g. coastline, railway, and highway). For example, photographs tagged with “coastline” are almost all taken at around a coastline. Therefore, we infered that coastlines can be extracted from photographs tagged with “coastline”. A novel method of extracting and drawing lines on a map was proposed and evaluated. Results show that the distance between lines of 64%-82% of our method and a coastline is less than or equal 500m. In addition, we applied this method to other tags, and results represent a geographical characterization that the tag represents.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"16","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2015-03-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"8"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":141567,"updated":"2025-01-20T19:20:03.151597+00:00","links":{},"created":"2025-01-19T00:19:08.039936+00:00"}
