Overview This is a temporal higher-order network dataset, which here means a sequence of timestamped simplices where each simplex is a set of nodes. Under the Drug Listing Act of 1972, the U.S. Food and Drug Administration releases information on all commercial drugs going through the regulation of the agency, forming the National Drug Code (NDC) Directory. In this dataset, each hyperedge corresponds to an NDC code for a drug, and the nodes are substances that make up the drug. Timestamps are in days and represent when the drug was first marketed. We restricted to hyperedges containing at most 25 nodes. Statistics Number of nodes: 5,311 Number of timestamped hyperedges: 112,405 Number of unique hyperedges: 10,025 Changelog v0.2: Updated format to HIF Source of original data Source: NDC-substances.
