We introduce a novel set of social network analysis based algorithms for mining the Web, blogs, and online forums to identify trends and find the people launching these new trends. These algorithms have been implemented in Condor, a software system for predictive search and analysis of the Web and especially social networks. Algorithms include the temporal(More)
This chapter reviews core concepts of peer-to-peer (P2P) networking. It highlights the management of resources, such as bandwidth, storage, information, files, and processor cycles based on P2P networks. A model differentiating P2P infrastructures, P2P applications, and P2P communities is introduced. This model provides a better understanding of the(More)
The future of networking will be shaped by open, heterogeneous and complex structures, consisting of many independent information systems, which may cooperate with other systems if advantageous, but usually work in an autonomous, self-interested and not necessarily cooperative way. In this article, we propose a novel approach for information system design(More)
This paper contributes to the ongoing stream of research correlating social network structure with individual and organizational performance. While teaching a course on optimizing online communication behavior and social network analysis, we collected preliminary data on the relationship between dynamic social network structures and individual and team(More)
It is becoming more and more important for knowledge workers to increase their productivity. However, there is a general lack of (semi-)automated, IT-supported data collection and evaluation approaches that allow insights into the processes and structures of an enterprise's internal networks and the activities of its knowledge workers. The article presents(More)
Historical examples (ISDN, Teletex, telefax, telex) show us that forecasting efforts in the telecommunication sector can go awry – not only by a few percentage points but by large magnitudes. We maintain that with strong network effects it is not possible to forecast the success of telecommunication services with a high degree of confidence. This paper(More)
In this paper, we describe the goals, organization and content of a global project course we have taught for the last six years, as well as challenges and lessons learned. The course has involved two to four sites and 30-40 students each year, both from Europe and the US. The students form project teams spanning several sites, and jointly perform creative(More)
