The integration requires heterogeneous combinations of text handling operations such as text search and clustering. Drawing an analogy with the relational data model, we propose a text representation model that represents documents in a formal manner, i.e. text representation, and that provides a text representation algebra that consists of procedures for handling the lists of the representations. We use subject graphs as the representation; node weight is used to represent the significance of each term, and link weight is used to represent that of each term-term association. This paper introduces a graphbased text database based on the model and an application for integrating document contents. Examples show that the proposed technique can discover important facts. Furthermore, evaluations show that subject graphs are more suitable for representation than term vectors with regard to the ap licability of procedures and readability. We also show the limitations of the model and that the computational complexity of subject graphs is reasonable.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"83","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"70","bibliographicIssueDates":{"bibliographicIssueDate":"2005-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG5(TOD25)","bibliographicVolumeNumber":"46"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"links":{},"id":17525,"updated":"2025-01-22T23:17:08.785081+00:00"}
