ミュージアムにおける展示物推薦 Museum Exhibit Recommendation
展示物の意外な共通点から、新たな発見と再訪を促す推薦手法の研究 Recommendation methods that encourage new discoveries and museum revisits through surprising commonalities between exhibits
国立民族学博物館との共同研究で、ミュージアムの再訪につながる新たな展示物との出会いを目指し、鑑賞済みの展示物と意外な共通点を持つ未鑑賞展示物を発見する手法を研究しています。
「意外な共通点」を「似ていないもの同士の共通点」と定義し、展示物とタグをノードとするグラフ上で意外度を測定します。 グラフ上で展示物同士を繋ぐ直接の経路を切断する前後の、相互の到達確率の分布の差から意外度を計算します。
実験では、被験者が展示物の画像とメタデータを見て意外度を答えるタスクを行い、任意の展示物と確かに意外な共通点を持つ展示物を発見できることが明らかになりました。
In joint research with the National Museum of Ethnology, we study methods that reveal unviewed exhibits with surprising commonalities to previously viewed exhibits, creating new discoveries that encourage museum revisits.
We define “surprising commonalities” as shared properties between dissimilar exhibits and measure the degree of surprise on a graph with exhibits and tags as nodes. The surprise score is calculated by measuring the difference in mutual reachability probability distributions before and after cutting direct paths between exhibits.
In an experiment, participants viewed exhibit images and metadata and rated their degree of surprise. The results showed that the method can identify exhibits with genuinely surprising commonalities with any given exhibit.
