“…Research on news sharing networks is highly focused on technological aspects and thus dominated by scholars from the computer and information sciences. Hence, the analyzed studies try, for example, to uncover topological or temporal characteristics of news sharing (e.g., Kwak, Lee, Park, & Moon, 2010; Peng & Marculescu, 2013), develop models or algorithms to predict news sharing cascades in social media (e.g., Goyal, Bonchi, & Lakshmanan, 2010; Lerman & Galstyan, 2008; Myers, Zhu, & Leskovec, 2012), or investigate how independent decisions by social media users ultimately lead to distinct network structures and sharing characteristics (e.g., Hu et al, 2012; Kim, Newth, & Christen, 2014). In this area of research, the term “network” is used to refer to two related but nonetheless distinct phenomena.…”
