Overview

This dataset is derived from tags on Stack Overflow posts. Each hyperedge corresponds to all of the tags used in a post, and each node in a hyperedge corresponds to a tag. The timestamps of the posts are in millisecond resolution, are adjusted so that the time of the earliest tag starts at 0, and are in ISO8601 format.
