“…Looking beyond the network-focused clusters, we observed some clusters cohering around methods and methodology development: ones around online experiments (e.g., Kohavi et al, 2013Kohavi et al, , 2009Kohavi et al, , 2014, natural-language processing (e.g., Huang et al, 2012;Miller, 1995), and applications of mobile-phone-based trace data (Eagle and Pentland, 2006;Gonzalez et al, 2008). With further clusters, there is clear emphasis on well-known sub-disciplines in various domains of the social sciences, from political science topics such as international relations (Datta, 2009;Simmons et al, 2006) and elections (Boix, 1999;Shepsle, 1979), through sociology-linked foci such as immigration and acculturation (Ali et al, 2003;Gordon, 1964) along with analytical sociology (Axelrod and Hamilton, 1981;Nowak and May, 1992), to economics and decision science (Kahneman and Tversky, 2013;Kahneman et al, 1982). Also visible are clusters around emerging research fields wherein digitalisation has opened new topics for enquiry.…”
