# STKGA: Simple-HHEA Temporal Knowledge Graph Alignment Dataset

This dataset contains two temporal knowledge graph (TKG) alignment benchmarks used in the Simple-HHEA paper, derived from ICEWS (Integrated Crisis Early Warning System).

## Dataset Structure

Each sub-dataset (`icews_wiki` and `icews_yago`) contains entity alignment data between two knowledge graphs (KG1 and KG2):

| File | Description |
|------|-------------|
| `ent_ids_1` | Entity IDs for KG1 (tab-separated: `id\tentity_name`) |
| `ent_ids_2` | Entity IDs for KG2 (tab-separated: `id\tentity_name`) |
| `rel_ids_1` | Relation IDs for KG1 (tab-separated: `id\trelation_name`) |
| `rel_ids_2` | Relation IDs for KG2 (tab-separated: `id\trelation_name`) |
| `triples_1` | Temporal triples for KG1 |
| `triples_2` | Temporal triples for KG2 |
| `sup_pairs` | Supervised (training) entity alignment pairs |
| `ref_pairs` | Reference (testing) entity alignment pairs |
| `ref_ent_ids` | Reference entity ID mappings between KG1 and KG2 |
| `time_id` | Temporal timestamp IDs (tab-separated: `id\ttimestamp`) |
