2 つのステップで，SNS データから観光地の環境に興味・関心がある人を見つけることを目的とする．はじめに，ユーザーの環境保護に対する意識を把握するために，観光地に関する写真やコメントの投稿を，ユーザーが焦点を当てたテーマに分類する自動分類器を作成する．次に，ユーザーの環境問題に対する興味の有無と，彼らが投稿する画像やコメントの関係性を調査するために，観光地における環境問題に関するアンケートを実施する．具体的には，観光地を訪れた人が撮影するときに焦点を当てたテーマを 4 つ定義し，これらのテーマを基に評価データセットを作成した．画像は CNN 分類器，コメントは LSTM 分類器を用いて実験を行った結果，画像分類の正解率で 75.4% を示した．さらに，アンケートに回答したユーザーの投稿画像を収集し，未知のテストデータとして自動分類することで，ユーザーが投稿した画像のテーマの割合と意識に関係があることが明らかになった．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告ドキュメントコミュニケーション（DC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-03-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2021-DC-120"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T18:05:42.034205+00:00","links":{}}
