We evaluated recommendation accuracy of CF with a dataset containing 29 open source software development projects (including 2,558 used components). As a result, the hypothesis (2) was supported, and the recommendation accuracy of CF showed better performance than the conventional methods and the median of NDPM was improved from 0.55 to 0.33 for low-generality components.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_7_publisher_10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会","subitem_publisher_language":"ja"}]},"item_7_rights_11":{"attribute_name":"出版者URL","attribute_value_mlt":[{"subitem_rights":"http://id.nii.ac.jp/1001/00009254/"}]},"item_7_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
