In order to apply such IR systems to large and homogeneous data such as newspaper articles and patent documents, it is necessary to improve the effectiveness of the document ranking they produce. In this paper, we propose a new IR model which utilizes the linguistic information as well as words tatistics information to improve its effectiveness. To conceptualize the model, we examine and analyze the human process of selecting relevant documents. We have developed a search system for newspaper articles realizing proposed IR model. AI-though it is an experimental system, it can index and search giga-byte data in practical computational time and spaces. We address the implementation of the system briefly and show the results of some experiments on its retrieval effectiveness. The results show that it can improve the precision of the upper part of the document ranking when the queries are deliberately constructed.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"40","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告情報学基礎（FI）"}],"bibliographicPageStart":"33","bibliographicIssueDates":{"bibliographicIssueDate":"1996-11-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"116(1996-FI-044)","bibliographicVolumeNumber":"1996"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
