+'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/ICEWS14", "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,
