[[OpenReview]](https://openreview.net/forum?id=oaGdsgB18L)
[[arXiv]](https://arxiv.org/abs/2205.14307)

- Built over ICEWS and GDELT, which are widely used benchmarks in TKGC.
- First introduced in paper "TFLEX: Temporal Feature-Logic Embedding Framework for Complex Reasoning over Temporal Knowledge Graph"
- Please refer to the original paper for more details.

## 🔬 Usage

```python
>>> dataset = load_dataset("linxy/GDELT", "all")
>>> len(dataset["train"]) + len(dataset["validation"]) + len(dataset["test"])
22117475
>>> dataset["train"][0]
{'query_name': 'Pe',
 'definition': 'def Pe(e1, r1, t1): return Pe(e1, r1, t1)',
 'query': [483, 18, 217],
 'answer': [26, 33, 40, 45, 65, 105, 107, 121, 139, 172, 187, 216, 264, 270, 313, 460, 480, 493],
 'easy_answer': [],
 'args': ['e1', 'r1', 't1']}
>>> dataset["test"][0]
{'query_name': 'Pe2',
 'definition': 'def Pe2(e1, r1, t1, r2, t2): return Pe(Pe(e1, r1, t1), r2, t2)',
 'query': [242, 38, 229, 1, 244],
 'answer': [9, 11, 24, 46, 76, 121, 140, 146, 209, 275, 280, 300, 380, 445, 463, 484],
 'easy_answer': [9, 11, 24, 46, 76, 146, 280, 300, 380, 445, 484],
 'args': ['e1', 'r1', 't1', 'r2', 't2']}
```

'args' is the argument list of the query function, where name starting with 'e' is entity, and 'r' for relation, 't' for timestamp.

assert len(query) == len(args)

In order to decode query ids into text, we should use a vocabulary (i.e. entity2idx, relation2idx and timestamp2idx).
Therefore, we use the code below to load meta info which contains the vocabulary:

```python
>>> dataset = load_dataset("linxy/GDELT", "meta")
>>> meta_info = dataset_meta["train"][0]
>>> meta_info
{'dataset': 'GDELT',
 'entity_count': 500,
 'relation_count': 20,
 'timestamp_count': 366,
 'valid_triples_count': 330906,
 'test_triples_count': 330845,
 'train_triples_count': 2308165,
 'triple_count': 2969916,
 'query_meta': {'query_name': [...], 'queries_count': [...], 'avg_answers_count': [...], ...},
 'entity2idx': {'name': [...], 'id': [...]},
 'relation2idx': {'name': [...], 'id': [...]},
 'timestamp2idx': {'name': [...], 'id': [...]},
```

Since the ids in the vocabulary are already sorted, we directly decode to access the name text:

```python
>>> query
[483, 18, 217]
>>> args
['e1', 'r1', 't1']
>>> for idx, arg_type in zip(query, args):
        if arg_type.startswith('e') or arg_type.startswith('s') or arg_type.startswith('o'):  # s, o, e1, e2, ...
            print(idx, meta_info['entity2idx']['name'][idx])
        elif arg_type.startswith('r'):  # r, r1, r2, ...
            print(idx, meta_info['relation2idx']['name'][idx])
        elif arg_type.startswith('t'):  # t, t1, t2, ...
            print(idx, meta_info['timestamp2idx']['name'][idx])
```

Besides, we also provide query-type-specific subparts.

```python
>>> dataset = load_dataset("linxy/GDELT", "e2i")
>>> some_datasets = [load_dataset("linxy/GDELT", query_name) for query_name in meta_info['query_meta']['query_name']]
```
