My research focus is on integration of algorithms for community detection, ranking and recommendations into folksonomy systems. Our system BibSonomy will be used as basis for the results. The overall goal is to enhance the Social Semantic Desktop, which we aim to build in the NEPOMUK project, with these algorithms.

Source Code

FolkRank

FolkRank is an algorithm for search and ranking in collaborative tagging systems. It has been integrated into the community support architecture of the social semantic desktop developed by the NEPOMUK project. The source code is available from the project's SVN repository.

Trias

Trias is an algorithm for computing triadic concepts which fulfill minimal support constraints. The source code is available on the project page.

BibSonomy

Some of the modules which BibSonomy is based on are available in a Maven repository. There is also a project page which contains an issue tracker.
