An emerging trend of the Web has been the widespread growth, expanse and popularity of a number and the size of social media systems (including blogs, wikis, Twitter, Facebook). With their ease of access and participation, social media provides a podium to millions of individuals today to express their thoughts, ideas, opinions, sentiments, interests and so on, exceedingly easily; virtually anytime, anywhere. Social media systems have thereby generalized the conventional notion of a hyperlink to imply connections between individuals in particular, via their shared content, media and concepts. A characteristic property of this new genre of connections is that they promote rich social interactions among individuals involved in the sharing and artifact-building process. However, the growing popularity of these systems might cause some challenges at the same time: whether it is motivating new users to participate, sustaining communities over time, managing social media traffic or deciphering the large information spaces engendering the interactions.
Making sense of these complex interactions has therefore invited significant attention in various research communities in the recent past. This track is geared towards developing deeper insights into the mechanisms of information exchange, user and network characterization as well as the discovery, analysis, and modeling of evolutionary social processes in these systems. It provides a key forum for researchers and industry practitioners to exchange information regarding advancements in the current state of art. Addressing several problems in this space necessitates expertise in a variety of domains, spanning Computer and Information Science, Social Sciences, Psychology, Math and Economics. Hence submissions promoting interdisciplinary collaboration are highly encouraged.
