My research is focused on the development and integration of algorithms for community detection, ranking and recommendations into collaborative tagging systems. Further topics of interest include citation and link analysis, entity matching and resolution, and social network analysis.
Furthermore, I am leading the development of our own system, BibSonomy, which is used as test-bed for our methods and results.
