			of BibSonomy for the challenge. A training dataset for both tasks is provided at the beginning of the competition. 
			The test dataset will be released 48 hours before the final deadline. Due to a very tight schedule we cannot grant any deadline

			The presentation of the results will take place at the ECML/PKDD workshop where the top teams are
