This is a temporal hypergraph dataset, which here means a sequence of timestamped hyperedges where each hyperedge is a set of nodes. In this dataset, nodes are US Congresspersons and hyperedges are comprised of the sponsor and co-sponsors of legislative bills put forth in both the House of Representatives and the Senate. Timestamps are in ISO8601 format. The dataset was derived from James Fowler's data.<br> <br> <strong>Statistics</strong><br> Some basic statistics of this dataset are:<br> * number of nodes: 1,718<br> * number of timestamped hyperedges: 282,049<br> * there is a single connected component of size 1,718<br> * degree and edge size distributions:<br> <br> <br> <br> <br> <b>Hypergraph degree and edge size distributions</b><br> <br> <strong>Source of original data</strong><br> Source: https://www.cs.cornell.edu/~arb/data/congress-bills/<br> <br> <strong>References</strong><br> If you use this dataset, please cite these references:<br> * Simplicial closure and higher-order link prediction.
