	### Dataset Summary

	The ASSIN 2 corpus is composed of rather simple sentences. Following the procedures of SemEval 2014 Task 1.
	The training and validation data are composed, respectively, of 6,500 and 500 sentence pairs in Brazilian Portuguese,
	annotated for entailment and semantic similarity. Semantic similarity values range from 1 to 5, and text entailment
	classes are either entailment or none. The test data are composed of approximately 3,000 sentence pairs with the same
	annotation. All data were manually annotated.

	### Supported Tasks and Leaderboards

	[More Information Needed]

	### Languages

	The language supported is Portuguese.

	## Dataset Structure

	### Data Instances

	An example from the ASSIN 2 dataset looks as follows:

	```
	{
	"entailment_judgment": 1,
	"hypothesis": "Uma criança está segurando uma pistola de água",
	"premise": "Uma criança risonha está segurando uma pistola de água e sendo espirrada com água",
	"relatedness_score": 4.5,
	"sentence_pair_id": 1
	}
	```

	### Data Fields

	- `sentence_pair_id`: a `int64` feature.
	- `premise`: a `string` feature.
	- `hypothesis`: a `string` feature.
	- `relatedness_score`: a `float32` feature.
	- `entailment_judgment`: a classification label, with possible values including `NONE`, `ENTAILMENT`.

	### Data Splits

	The data is split into train, validation and test set. The split sizes are as follow:

	\| Train \| Val \| Test \|
	\| ------ \| ----- \| ---- \|
	\| 6500 \| 500 \| 2448 \|
