Repositories are being popular as places for publication of research outputs. To make more efficient use of scholarly information on the internet, repositories are required to cooperate with other databases. One of the essential processes of the cooperation is identification of scholarly papers and their authors. The straightforward approach is string matching of the title and authors' name, however this approach cannot always solve the difficulties by basic clerical errors and same names. This paper proposes a method to compensate for the inaccuracy of the identification by connecting different databases. The main idea of the method is that different metadata of a scholarly paper is linked by the authors themselves, therefore the correspondence is guaranteed by the authors. The authors of this paper are developing a system based on the idea on the repository and the researcher database in their university.
