We propose a simple probabilistic model that assumes that an image is generated from latent intents that each represent primitive image factors such as colour, shape, and texture. This enables us to automatically compute a graded relevance score for each retrieved image, and thereby to compute graded relevance evaluation measures such as nDCG (normalised Discounted Cumulative Gain) without relying on human relevance assessments. We evaluate how the proposed measure, which we call I-nDCG, aligns with human preference judgments through a large-scale crowdsourcing experiment. Moreover, we show that image search result diversification methods can naturally be derived based on our model by following the approaches of existing diversity evaluation measures, namely, D-nDCG and intent-aware measures.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-09-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"2018-DBS-167"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:57:07.537653+00:00","id":191218,"links":{}}
