The World Wide Web supports new styles of creative activities. For
this study, we investigate massively collaborative creation via the Web, by
which numerous people gather to evolve their works collaboratively. Nico Nico
Douga is a video sharing website, where many videos are created
collaboratively. We specifically examine Hatsune Miku, a version of singing
synthesizer application software that has inspired not only song creation but
also songwriting, illustration, and video editing. As described herein,
different types of creators interact to create new contents though their
social network. Using tags, we classified videos and creators on Nico Nico
Douga automatically into four basic categories. Thereby, we produced a social
network from relationships among videos and creators by analyzing videos’
descriptions. The social network reveals interesting features. Different
categories of creators serve different roles in evolving the network, e.g.,
songwriters gather more links than other categories, implying that they are
triggers to network evolution. We also extracted communities from the network
and observed different community structures. One is a centralized network in
which a single songwriter is central and others are peripheral. The other is
a messier network, in which some illustrators are central, but the centrality
is weak.
