TimeReach (EDBT 2015)

We publish three data sets: Facebook, Youtube, and Flickr that we used in our published work TimeReach: Historical Reachability Queries on Evolving Graphs.
The data sets conform with the following format:
--------------------------------------------
nodeID1 nodeID2 timeInterval
--------------------------------------------
Each line refers to an edge between two nodes. The time interval refers to the total duration where the edge was alive. Please refer to the paper for more details on the data sets.

The following table gives links for the three data sets:
