Their programming languages are undocumented. Therefore, their respective programming languages are not easily judged by hand. Although detecting a programming language for each file is necessary for various program analysis tasks, it is time consuming to manually analyze a large amount of files. In this research, we propose a method to support the process of programming language detection employing a clustering technique to select a small number of representatives for manual detection of programming languages. To improve accuracy, our method combines pattern matching and a static analysis using a result of manual detection. In the experiment, we applied our method to two actual legacy systems whose source code files have been manually analyzed. As a result, our method correctly classified 99.49% of the 190,000 files. While a manual detection of programming languages for the systems required 3.3 man-months, our method completed the analysis in eight hours for computation and fifteen minutes for manual checks of programming languages.","subitem_description_language":"en","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/1001/00189912/ | http://id.nii.ac.jp/1001/00189912/"}]},"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（社）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。","subitem_rights_language":"ja"},{"subitem_rights":"Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
