Proposed interdisciplinary work presents conceptual framework for the simulation of information-based social networks. Some new principles and approaches are introduced. This paper, however, concentrates more on one key aspect, i.e. virtual computational field approach (VCF). In fact, VCF constructs a virtual medium for information and resources exchange between heterogeneous social agents. Soc...

Despite many works on collaborative networked organizations (CNOs), CSCW, groupware, workflow systems and social networks, computer support for virtual teams is still insufficient, especially support for agility, i.e. the capability of virtual team members to rapidly and cost efficiently adapt the way they interact to changes. In this paper, requirements for computer support for agile virtual t...

The characterization and assessment of the social capital of a member in collaborative networks is an important element to help promoting the success of collaborative networks. However, models to measure the social capital are lacking. Applying some concepts from social networks theory, this paper discusses some perspectives and criteria to identify and measure the value of social capital of a ...

Ambient Intelligence creates scenarios in which the reality is modified by devices that augment the possibilities of social interaction. In this paper we propose an approach based on institutions to describe and model the virtual reality created by an application of Ambient Intelligence. First, using the multiagent systems, we give a model of institution in terms of the relations of power and d...

The discovery of community structure in networks is a problem of considerable interest in recent years. In online social networks, often times, users are simultaneously involved in multiple social media sites, some of which share common social relationships. It is of great interest to uncover a shared community structure across these networks. However, in reality, users typically identify thems...

e-Learning has turned to be a necessity for everyone, as it enables continuous and life-long education. Learners are social by nature. They want to connect to othersand share the same interests. Online communities are important to help and encourage learners to continue education. Learners through social capabilities can share different experiences.Social networks are cornerstone for e-Learning...

In this paper, we report on the initial design and implementation of a project entitled RE@L Research Environments Associated with Learning through Social Networks. Our goal is to examine how future science gateways that rely on immersive virtual environments and Web 2.0 technologies can bridge the gap between research and education. To this end, we strategically apply middleware technologies i...

Social networks are analyzed and mined to find communities, or groupings of interrelated entities. Community mining provides this higher level of structure and offers greater understanding, but networks change over time. Their constituent communities change, and the elements of those communities change over time as well. By performing event analysis, the evolutions of communities are abstracted...
