	## Dataset Description
	- Repository: [https://hadyelsahar.github.io/t-rex/](https://hadyelsahar.github.io/t-rex/)
	- Paper: [https://aclanthology.org/L18-1544/](https://aclanthology.org/L18-1544/)
	- Dataset: Cleaned T-REX for link prediction.

	## Dataset Summary
	This is the T-REX dataset proposed in [https://aclanthology.org/L18-1544/](https://aclanthology.org/L18-1544/).
	The test split is universal across different version, which is manually checked by the author of [relbert/t_rex](https://huggingface.co/datasets/relbert/t_rex),
	and the test split contains predicates that is not included in the train/validation split.
	The train/validation splits are created for each configuration by the ratio of 9:1.
	The number of triples in each split is summarized in the table below.

	*Note:* To make it consistent with other datasets ([nell](https://huggingface.co/datasets/relbert/nell) and [conceptnet](https://huggingface.co/datasets/relbert/conceptnet)), we rename predicate/subject/object as relation/head/tail.

	### Filtering to Remove Noise
	We apply filtering to keep triples with alpha-numeric subject and object, as well as triples with at least either of subject or object is a named-entity.
	After the filtering, we manually remove too vague and noisy predicate, and unify same predicates with different names (see the annotation [here](https://huggingface.co/datasets/relbert/t_rex/raw/main/predicate_manual_check.csv)).

	\| Dataset \| `raw` \| `filter` \| `filter_unified` \|
	\|:----------\|----------:\|----------:\|-----------------:\|
	\| Triples \| 941,663 \| 583,333 \| 432,795 \|
	\| Predicate \| 931 \| 659 \| 247 \|
	\| Entity \| 270,801 \| 197,163 \| 149,172 \|

	### Filtering to Purify the Dataset
	We reduce the size of the dataset by applying filtering based on the number of predicates and entities in the triples.
	We first remove triples that contain either of subject or object with the occurrence in the dataset that is lower than `min entity`.
	Then, we reduce the number triples in each predicate to be less than `max predicate`.
	If the number of triples in a predicate is higher than `max predicate`,
	we choose top-`max predicate` triples based on the frequency of the subject and the object, or random sampling.
