This year's discovery challenge deals with three tasks in the area of tag recommendations for social bookmarking services. The first task covers content-based, the second task graph-based tag recommendations. An additional third task allows participants to deliver online recommendations to a running social bookmarking service. The dataset the challenge is based on is a snapshot of the social bookmark and publication sharing system Bibsonomy http://www.bibsonomy.org/.
