Ostinato: The exploration-automation cycle of user-centric, process-automated data-driven visual network analytics

This chapter introduces the Ostinato Model, an exploration-automation cycle for a user-centric, process-automated, data-driven visual network analytics. In terms of increasing the transparency of editorial processes on social media, this chapter contributes to the general theme of the book and particularly its secondvolume at hand in three levels. First, network analysis is a key approach in supporting explorative studies on the patterns and structures in between actors creating, curating, refining, and distributing socialmedia content and in estimating the authority and trust these actors have, therefore allowing for increasing the transparency of the editorial structure of Wikipedia co-authors, discussion and dissemination structures on Twitter and other social media. These structures can be modeled, represented, analyzed and visualized as networks to support the investigations and exploration. Second, the presented data-driven approach allows extending these investigations beyond the boundaries of individual social media and over long periods of time. Third, actors with different sets of skills from means to crawl online sources for data to domain knowledge allowing deep sensemaking can all fully engage into the different phases of the investigative process.
