Since this mismatch between query terms and information need affects the topic difficulty, it is better to have a framework to evaluate the effectiveness of the query terms. Therefore, in this paper, I propose some feature quantities that characterize quality of initial query in test collection. I also analyze correlation coefficient between these quantities and retrieval performance by using NTCIR-4 web test collection.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"30","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"25","bibliographicIssueDates":{"bibliographicIssueDate":"2005-05-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"42(2005-DBS-136)","bibliographicVolumeNumber":"2005"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T22:22:50.017205+00:00","created":"2025-01-18T22:51:40.582752+00:00","id":19126}
