Social network analysis can be used to investigate collaboration in learning networks, which can be modeled as social graphs. We have already proposed a conceptual framework for knowledge extraction and visualization from a social media-based learning environment, starting from specific educational needs identified by the instructors. In the current paper, we experimentally validate this framework...
Researchers create larger networks of contacts through research collaboration, known as collaboration networks of researchers. In order to promote and to have effective collaboration among researchers, the collaboration patterns need to be accessed and analysed to elevate research and publication (R&P) performance. However, the collaboration patterns have not been accessed in the context of Universiti...
Group work skills are essential for Computer Scientists and especially Software Engineers. Group work is included in most CS curricula in order to support students in acquiring these skills. During group work, problems can occur related to a variety of factors, such as unstable group constellations or (missing) instructor support. Students need to find strategies for solving or preventing such problems...
Software development is a collaborative activity in which social relationships among those involved throughout the life cycle are paramount for achieving the project goals. For instance, communication with, awareness of, and trust in others are relevant and necessary to facilitate collaboration. The identification of social relationships and their patterns can help us to better understand the dynamics...
Human collaboration has become an integral part of large-scale systems for massive online knowledge sharing, content distribution, and social networking. Maintenance of these complex systems, however, still relies on adaptation mechanisms that remain unaware of the prevailing user collaboration patterns. Consequently, a system cannot react to changes in the interaction behavior thereby impeding the...
With the emergence of large-scale complex systems, the boundary between humans and software becomes increasingly blurry. Adaptation mechanisms thus need to consider the interaction structure amongst users to derive appropriate adaptation actions. Most existing systems, however, lack such collaboration awareness and thus cannot deliver the required flexibility that large-scale collaboration need to...
Human process involvement has gained momentum in recent years, but the proposed mechanisms can't efficiently adapt Web-scale collaborative workflows. Here, the authors describe collaborative problem solving and its integration with process-support systems as an architecture comprising human components and connectors. This modeling of coordination and execution roles enables reasoning on workflow flexibility...
Current collaboration technologies encompass a broad range of tools that enable groups of people to work together and collaboratively create and manage knowledge. To facilitate the efficient use of collaboration tools, patterns have been exploited as models for repeatable collaboration processes for recurring high-value collaborative tasks. We present Collaboration Patterns Assistant, a software tool...
In this study, we extract patterns from a large developer collaborations network extracted from Source Forge. Net at high and low level of details. At the high level of details, we extract various network-level statistics from the network. At the low level of details, we extract topological sub-graph patterns that are frequently seen among collaborating developers. Extracting sub graph patterns from...
Virtual world conferences have been shown to give users an increased sense of presence in a collaboration as opposed to teleconferences, video-conferences and web-conferences. Such telepresence encourages remote participants to engage in the collaboration. Current virtual world collaboration applications rely on mouse/keyboard interfaces to create pure-virtual collaborations. In this paper we propose...
This study examines communication behaviors in global software student teams. The authors of the paper characterize the types of communication behaviors that occur when student teams are engaged in a software development project. The authors present findings from a one-semester study that examined factors contributing to successful distributed programming interactions among students enrolled at the...
Facilitation is a key success factor for effective group support systems (GSS) applications. The development of effective support for facilitation becomes more critical than ever as decision making groups are larger and globally distributed. Developing support for a facilitator is a promising avenue for creating successful distributed GSS. This paper presents the results of a questionnaire to attain...
