On the other hand, people also perceive social relationships in the real world, which we forecast will be also structured as electronic data as the Internet-of-Things (IoT) devices will be developed. A question here is how different a social network structure in the real world is from the one perceived by people. There has been a variety of metrics measured from a social network structure like the centrality, the similarity measured from common neighbor nodes, the clustering characteristics and so on. Although these metrics have been used in influence estimation, new-friend prediction, and community extraction few researches have tackled how people perceive these metrics in the real world. Therefore, this report focuses on a metric named 'unexpected relationship between two people', which means the two people have a week or no direct relation, while they have high similarity. Then, our experiment results show how different the objective metric is from the one people perceive subjectively.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4","bibliographic_titles":[{"bibliographic_title":"研究報告ドキュメントコミュニケーション（DC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-07-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2016-DC-102"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":168209,"updated":"2025-01-20T09:25:44.393020+00:00","links":{}}
