The purpose of this paper is to clarify the creation process in mass collaboration. In order to accomplish this purpose, we analyzed how editors write articles in Japanese Wikipedia from 2002 to the end of June 2008 using several data logs of "Featured Articles". First, we classified editors into three types; "originator", "writer", and "corrector". As a result, we found that most of editors work as corrector. Second, we visualized the interactions among editors as networks, and classified them into four types. The results imply that Japanese Wikipedia has variety of editors' roles in common and the diversity of interaction structure between editors.
