The need is growing to collect and publish reviews. However, it cost a lot of time and money to make them write reviews. So it is hoped that the documents which are available for reviews can be collected automatically from the CGM such as blog. Such a document classification task has been performed by using classification learning in a document level. But it is difficult to determine whether a blog is a review or not because many other information are mixed. Therefore we have done classification in a sentence level in order to classify fine-grained. And then classification is done by the ratio of a review sentence. As the result, we achieve 72.3 in F-measure. Our method is superior to conventional methods by 26.4.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告情報基礎とアクセス技術（IFAT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-01-13","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2012-IFAT-105"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
