However, hit counts returned by search engines can fluctuate unnaturally when observed on different days, and may cause too large errors to be used in researches. Therefore, it is important to discuss on how we can evaluate and improve the reliability of hit counts. We have performed several researches about this problem such as a research to specify the conditions in which search engines can return reliable hit counts, and a research to define the reliability evaluation metrics. In this paper, in addition to the latter research, we'll report the result of validation experiments for the reliability evaluation metrics.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告 情報基礎とアクセス技術（IFAT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-07-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2011-IFAT-103"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:32:35.399189+00:00","id":75503,"links":{}}
