Overview
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 tags, and hyperedges are the sets of tags applied to questions on askubuntu.com. The timestamps are in ISO8601 format and are normalized to start at 0. This dataset is derived from tags on Ask Ubuntu posts.
