TL;DR: The datasets for the temporal knowledge graph reasoning task.

[Github] [OpenReview] [arXiv]

  • 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 

>>> dataset = load_dataset("linxy/GDELT", "all")
>>> len(dataset["train"]) + len(dataset["validation"]) + len(dataset["test"])
1088769
>>> dataset["train"][0]
{'query_name': 'Pe_aPt',
 'definition': 'def Pe_aPt(e1, r1, e2, r2, e3): return Pe(e1, r1, after(Pt(e2, r2, e3)))',
 'query': [6291, 372, 5683, 283, 5264],
 'answer': [1077],
 'easy_answer': [],
 'args': ['e1', 'r1', 'e2', 'r2', 'e3']}
>>> dataset["test"][0]
{'query_name': 'Pe',
 'definition': 'def Pe(e1, r1, t1): return Pe(e1, r1, t1)',
 'query': [1426, 115, 28],
 'answer': [3697],
 'easy_answer': [],
 'args': ['e1', 'r1', 't1']}

'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:

>>> dataset = load_dataset("linxy/GDELT", "meta")
>>> meta_info = dataset_meta["train"][0]
>>> meta_info
{'dataset': 'ICEWS14',
 'entity_count': 7128,
 'relation_count': 230,
 'timestamp_count': 365,
 'valid_triples_count': 8941,
 'test_triples_count': 8963,
 'train_triples_count': 72826,
 'triple_count': 90730,
 '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:

>>> query
[1426, 115, 28]
>>> 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.

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