In this paper we propose a weighted multi-hypergraph as logical structure to model relationships between researchers and interest groups that join them on the base of shared research topics in a given scientific community. The well known concept of eingenvector centrality for graphs is extended to weighted multi-hypergraphs and we present a model instantiation for centrality analysis in the Pro...

This paper presents an algorithm and a tool for discovering scientific communities. Several approaches have been proposed to discover community structure applying clustering methods over different networks, such as co-authorship and citation networks. However, most existing approaches do not allow for overlapping of communities, which is instead natural when we consider communities of scientist...

The Learning Through Collaborative Visualization Project (CoVis) is building an educational testbed to reform science education. The CoVis learning community uses next-generation technologies for collaboration and scientific visualization to support community formation and work-activities in high school science classrooms. An important project design goal is to create activities centered on mor...

The Internet has enabled profound changes in the way science is performed, especially in scientific communications. Among the most important of these changes is the possibility of new models for pre-publication review, ranging from the current, relatively strict peer-review model, to entirely unreviewed, instant self-publication. Different models may affect scientific progress by altering both ...

The recent interest in 'network' forms oforganization serves as a starting point to better understand the dynamic characteristics of technology development. Net-work theory allows one to describe the relations between 'actors' involved in the development of new technologies both crosssectionally and longitudinally and, as a consequence, to model the structural and behavioral development of a co...

In many sciences the increasing amounts of data are reaching the limit of established data handling and processing. With four large research centers of the German Helmholtz association the Large Scale Data Management and Analysis (LSDMA) project supports an initial set of scientific projects, initiatives and instruments to organize and efficiently analyze the increasing amount of data produced ...

Three Dutch scientific communities started the Roquade project: the Library of Utrecht University, the Library of Delft University of Technology and the Netherlands Institute for Scientific Information Services (niwi) (1). The Roquade project aims at enhancing scientific communication in the interest of the academic community. The control of most of its scientific output was outsourced for ages...

When making decisions about funding and jobs the scientific community should recognise that most of the tools used to evaluate scientific excellence are biased in favour of established disciplines and against interdisciplinary research.
