Based on the stationary distribution induced from the problem setting, we propose a similarity function among data objects, and represent the entire objects as an edge-weighted graph.

The proposed approach is evaluated on the text clustering problem over the 20 Newsgroup benchmark data. The results are encouraging and indicate the effectiveness of our approach.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告バイオ情報学（BIO）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-12-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"30","bibliographicVolumeNumber":"2009-BIO-19"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"updated":"2025-01-22T00:46:25.587084+00:00","created":"2025-01-18T23:27:37.341158+00:00","links":{},"id":67016}
