Abstract:
Collaborative tagging sites constitute a unique opportunity for leveraging implicit and explicit social ties in search and recommendations. This talk describes our work in the context of Royal Jelly, a platform for socially-aware recommendations in collaborative tagging sites. The key aspects of RJ are search over recommendations, topic derivation from tags, efficient recommendation algorithms and diversity in recommendations. We describe some of our solutions in that space and an overview of the challenges ahead.
