Tags from Delicious. Modes represent user-page-tag-date, where date is at the granularity of day. Non-zero values are binary, indicating that a user has tagged a webpage on a given day. The order-3 tensor is the same data with dates removed.

User and page ID mappings are only useful for reproducibility due to anonymization efforts. However, the tags and dates map to original data. Date IDs are ordered chronologically.
