Abstract

Developing social network visualizations based on collaborative activities can provide a meaningful statistical and topological understanding of the overall dynamics between individuals in a common setting, but without any additional layers of information, interpretation is left to the researcher and the dataset provided. We argue that visualizations based on points of interest can provide a better understanding and identification of centralized nodes and validation of groupings determined by a variety of clustering algorithms. We present two visualization systems SuperVIBE and ContextForces that implement this approach. These systems operate by creating two-dimensional latent spaces by means of grouping nodes using external variables not presented in the graph and by offering an interactive visualization to filter and map in these latent spaces. Understanding which latent groups are most central to a variety of topics and providing visual clues to the individuals critical to those groups provides a mechanism to explore and discover.
