摘要：The Web technology enables numerous people to collaborate in creation. We designate it as massively collaborative creation via the Web . As an example of massively collaborative creation, we particularly examine video development on Nico Nico Douga , which is a video sharing website that is popular in Japan. We specifically examine videos on Hatsune Miku , a version of a singing synthesizer application software that has inspired not only song creation but also songwriting, illustration, and video editing. As described herein, creators of interact to create new contents through their social network. In this paper, we analyzed the process of developing thousands of videos based on creators' social networks and investigate relationships among creation activity and social networks. The social network reveals interesting features. Creators generate large and sparse social networks including some centralized communities, and such centralized community's members shared special tags. Different categories of creators have different roles in evolving the network, e.g., songwriters gather more links than other categories, implying that they are triggers to network evolution.
