Context This dataset contains 70 synthetic dynamic networks to be used as benchmark for dynamic community finding. The network have been generate useing the DANCER framework. Content This dataset contains 70 synthetic dynamic networks to be used as benchmark for dynamic community finding. Each network is modeled as a sequence of snapshots where each snapshot represents the whole network state at a giving point in time. Each dataset comes with the ground truth for each snapshot. The ground truth tells to which community each node belongs. The dataset have been generated using the DANCER tool "Largeron, C., Mougel, P. N., Benyahia, O., & Za?ane, O. R. (2017). DANCer: dynamic attributed networks with community structure generation. Knowledge and Information Systems, 53(1), 109-151." Format of data: Each snapshot of the network is stored in a file "tn.graph
