Understanding Social Networks From a Multiagent Perspective

Abstract

Social networks have recently been widely explored in many fields; these networks are composed of a set of autonomous social actors and the interaction relations among them. Multiagent computing has already been widely envisioned to be a powerful paradigm for modeling autonomous multientity systems; therefore, it is promising to connect the research on social networks and multiagent systems. In general, there are three views for research on social networks: the structure-oriented view, in which only the network structure characteristics among actors are considered, the actor-oriented view, in which only the behavior characteristics of actors are considered, and the actor-structure crossing view, in which both actors and network structures are considered and their crossing effects are explored. This survey paper mainly concerns studies on social networks that have the last two views and discusses the relationship between social networks and multiagent systems. Because coordination is critical for both multiagent systems and social networks, this paper classifies studies on social networks that are based on the coordination mechanisms among the actors in the social networks. By referring to typical types of coordination situations in multiagent systems, social networks in previous studies can be classified into three classes: cooperative social networks, noncooperative social networks, and multiple social networks; for each class, this paper reviews the existing studies and discusses the challenge issues and possible future research directions. From this survey, we find that social networks can be understood well via a multiagent coordination perspective and also that many multiagent coordination techniques can be cogently applied in research on social networks. Moreover, this paper discusses the advantages and disadvantages of the multiagent coordination perspective by comparing with other perspectives on studying social networks.

Cooperative Multi-Agent Learning in Social Networks: A Review

“…Jiang and Jiang [12] answered the problem related to a social network that how to connect social networks and multi-agent systems and how to use multi-agent technologies to model and analyze social networks, by surveying social networks from a multi-agent perspective. The authors mainly reviewed the various related studies to the actor-oriented view and the actorstructure crossing view.…”

Towards understanding longitudinal collaboration networks: a case of mammography performance research

“…Two general perspectives can be considered in analysing social networks; the Structureoriented perspective, which examines the 'the networks topological characteristics' and the actor-oriented perspective, which investigates attributes and properties of 'social actors' behaviours' (Jiang and Jiang 2014). Both approaches are significant and may be applicable to different social networks.…”

“…Both approaches are significant and may be applicable to different social networks. The first approach is very useful when networks locational characteristics are of importance and the second approach is advantageous when attributes and behaviours of social actors, especially humans, have a major role in the network evolution (Jiang and Jiang 2014).…”

Analyzing users’ activity in online social networks over time through a multi-agent framework

“…In order to deal with this problem, we propose the use of Multi-Agent Systems [22,11]. Social networks can be well understood via a multi-agent perspective.…”
