Network Analysis of an Emergent Massively Collaborative Creation on Video Sharing Website
Transactions of The Japanese Society for Artificial Intelligence, 2010
The Web technology enables numerous people to collaborate in creation. We designate it as massively collaborative creation via the Web. It is becoming an important activity such as Wikipedia and Yahoo! QA. 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 though their social network. We analyzed the process of developing thousands of videos based on creators' social networks. The social network reveals interesting features. Different categories of creators serve different roles in evolving the network. We also extracted communities from the network and observed different community structures and investigated the evolving nature of the network using motif analysis.

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.

Characterizing the nature of interactions for cooperative creation in online social networks
Social Network Analysis and Mining, 2015
Many aspects of online social networks (OSN) have been studied in recent years. In this article, we focus on the question of interactions in large OSN. We propose methods to study these interactions, and apply them on a platform called Nico Nico Douga (NND), with the aim of understanding cooperative behaviors, taking the form of collective creation of music videos in NND. Our first contribution is a method that, starting from the network of interactions between users, evaluates three aspects: the impact of the social structure on these interactions, their concentration, and their reciprocity. We characterize the nature of interactions in NND, and compare it with four different datasets. We find that interactions in NND are more similar to a diffusion process, such as retweets in Tweeter, than to interpersonal communications, or even to cooperation in science. Our second contribution is a typology of roles for productions in a cooperative process. These roles are attributed based on the neighborhood of the nodes in the network of references between productions. We define direct roles, relative roles, and indirect roles. We subsequently study the frequency of these roles in NND. We show a correlation between the category of the contribution of a video (song, animation, etc.) and its probability of having a certain role. We also find a positive correlation between the most active users and the production of videos playing an important role in the cooperation process.
How can people create contents collaboratively without collaboration?
The Web technology enables numerous people to collaborate in creation. We designate it as massively collaborative creation via the Web. It is becoming an important activity such as Wikipedia and Yahoo! QA. It has an interesting characteristic, especially in an entertainment content creation. People create their own content freely and there is few explicit coordination to create contents. We are interested in the development of such digital works and investigate them using network analysis.
Small world networks and creativity in audio clip sharing
International Journal of Social Network Mining, 2012
Sharing communities are changing the way audio clips are obtained in several areas, ranging from music to game design. The motivations for people to record and upload sounds to these sites are likely to be related to social factors. In this paper, we describe several networks that can be extracted from user activities in these systems. We propose the notion of creativity as an objective for this kind of community, and how some indicators of creativity can be extracted. We investigate the relationship between the network properties and the creative outcome indicators through an empirical analysis of data from Freesound.org, a widely used website for sharing audio clips.

In this paper, we will attempt to move beyond the individual case study by undertaking a comparative analysis of two highly successful online remixing communities: ccMixter, an online community devoted to the sharing and remixing of music, and Scratch, an online community focused on enabling young people to create and share interactive games and animations. This paper employs a mixed methods approach towards comparing both remixing communities. We utilized Social Network Analysis (SNA) as a means of characterizing the sharing and remixing activity in both communities. The SNA also functioned as a sampling method to identify a small core of users who were most active in each community. Interviews were then conducted with this set of core members.
The sharing of wonderful ideas : influence and interaction in Online Communities of Creators
2007
This thesis presents a new framework for understanding how communities of creators share work, influence one another's creative processes, and learn from one another. I introduce the concept of Online Communities of Creators (OCOCs), which are online communities where the core activity is sharing personal creations. These communities can play an important part in the development of the Creative Society by providing venues for people to encourage each other's creative processes and output. By fostering each other's desires to create and share, these communities help individuals to experience the joy of designing, creating, and sharing.
