email-EU
Description
Nodes represent email addresses. Each hyperedge represents an email exchange involving the set of participating addresses (and may include a timestamp/weight when available).
Basic statistics
- Nodes: 1005
- Hyperedges: 209508
- Unique hyperedges: 24520
- Max size hyperedge: 40
Hypergraph metadata
| Property | Description |
|---|---|
| name | (STRING) Dataset name (e.g., email-EU). |
| type | (STRING) Hypergraph type (e.g., TemporalHypergraph). |
| version | (STRING) Dataset version (e.g., 1.0.0). |
| weighted | (BOOL) Whether the hypergraph is weighted (e.g., true). |
Hyperedge metadata
| Property | Description |
|---|---|
| original_timestamp | (INT) Raw email timestamp from the source data, recorded at one-second resolution (e.g., 1064021027). |
| time | (INT) Normalized email timestamp, equal to original_timestamp minus the first raw timestamp in the dataset (e.g., 0). |
| weight | (INT) Number of email records collapsed into this sender/recipient set at the same timestamp (e.g., 1). |
