This paper proposes a context approach of social networks and virtual communities in the enterprise area. We point out that making context explicit it is possible to provide a global picture of the main aspects of social networks. A first result of this study is that the explicit consideration of contexts—especially shared contexts—could improve notably the collaborative-work processes in an en...

Online platforms are virtual places where people interact for different purposes, thus forming online communities. So far several mining methods have been developed to detect these community structures as densely connected subgraphs in networks. The evolution of these networks is typically analyzed by observing changes in the interaction behavior of single members only. However, we observe that...

This paper proposes a research agenda for studying factors that may affect marketing effectiveness in the context of online communities. Findings of prior studies are synthesized into a more comprehensive review of the state of the art of research on word of mouth marketing through online social networks. Based on the review, we propose a research model that incorporates both network and indivi...

The aim of this study is to investigate, on the one hand, the main effects of personal innovativeness and familiarity on perceived community support in the domain of the social network site Tuenti, and, on the other hand, the moderating effects of personal innovativeness on relationships between familiarity and perceived community support. A Structural Equation Modelling, specifically Partial L...

The usage of social software and virtual community platforms in particular promises to offer opportunities for customer integration approaches into a company’s value creation activities. Therefore, ideas and innovations generated by members of a virtual community can be analyzed and used in order to enhance the quality of firm’s products and services. However, evaluating economic consequences a...

Although researchers have pointed out relationships among members as being essential for the building of commitment towards a community, there is still insufficient attention placed on this in virtual community research. Furthermore, the effect of size on this relational aspect of virtual community has also been given little emphasis in the existing literature despite being acknowledged by exta...

In this paper we present first experimental results about a small group of people exchanging private and public messages in a virtual community. Our goal is the study of the cognitive network that emerges during a chat seance. We used the Derrida coefficient and the triangle structure under the working assumption that moods and perceived mutual affinity can produce results complementary to a fu...

In many scientific fields, from biology to sociology, community detection in complex networks has become increasingly important. This paper, for the first time, introduces Cooperative Co-evolution framework for detecting communities in complex networks. A Bias Grouping scheme is proposed to dynamically decompose a complex network into smaller subnetworks to handle large-scale networks. We adopt...

The study of community networks has attracted considerable attention recently. In this paper, we propose an evolving community network model based on local events, the addition of new nodes intracommunity and new links intraor inter-community. Employing growth and preferential attachment mechanisms, we generate the network with a generalized power-law distribution of nodes’ degrees. Furthermore...
