Users often input the facility name as a search query, but some POIs may have the same facility name. Furthermore these search results are oftenly unsorted, so a globaly famous POI is listed with a local POI. This situation affects the user experience when POI searching. To solve this problem, the distance between POIs and the current location is used to rank the POI around the user higher, but it is usual that users want a famous landmark far away is ranked ahead of near POIs that have same name. We assign facility popularity according to the number of posts refering to the POI on social media and the number of people staying around the POI during daylight, and aimed to rank the POI expected for many users higher by using a sort order that also includes facility popularity. In our evaluation, proposed method improved search accuracy about 13% for the search log of tourist facilities and destination facilities in car navigation application for the smartphone.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"274","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"263","bibliographicIssueDates":{"bibliographicIssueDate":"2021-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"62"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00208894","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"id":208996,"links":{}}
