Optimizing strategies for the exploration of social networks and associated data collections

Multimedia data collections immersed into social networks may be explored from the point of view of varying documents and users characteristics. In this paper, we develop a unified model to embed documents and users into coherent structures from which to extract optimal subsets. The result is the definition of guiding navigation strategies of both the user and document networks, as a complement to classical search operations. An initial interface that may materialize such browsing over documents is demonstrated in the context of cultural heritage.
