### Dataset Summary

TE-ca is a dataset of textual entailment in Catalan, which contains 21,163 pairs of premises and hypotheses, annotated according to the inference relation they have (implication, contradiction or neutral).

This dataset was developed by [BSC TeMU](https://temu.bsc.es/) as part of [Projecte AINA](https://politiquesdigitals.gencat.cat/ca/economia/catalonia-ai/aina/), to enrich the [Catalan Language Understanding Benchmark (CLUB)](https://club.aina.bsc.es/).

### Supported Tasks and Leaderboards

Textual entailment, Text classification, Language Model

### Languages

The dataset is in Catalan (`ca-ES`).

## Dataset Structure

### Data Instances

Three JSON files, one for each split.

### Example:

<pre>
    
    {
        "id": 3247,
        "premise": "L'ONU adopta a Marràqueix un pacte no vinculant per les migracions",
        "hypothesis": "S'acorden unes recomanacions per les persones migrades a Marràqueix",
        "label": "0"
    },
    {
        "id": 2825,
        "premise": "L'ONU adopta a Marràqueix un pacte no vinculant per les migracions",

        "label": "1"
    },
    {
        "id": 2431,
        "premise": "L'ONU adopta a Marràqueix un pacte no vinculant per les migracions",
        "hypothesis": "L'acord impulsat per l'ONU lluny de tancar-se",
        "label": "2"
    },
</pre>

## Dataset Creation

### Curation Rationale
We created this dataset to contribute to the development of language models in Catalan, a low-resource language.

### Source Data

Source sentences are extracted from the [Catalan Textual Corpus](https://doi.org/10.5281/zenodo.4519349) and from [VilaWeb](https://www.vilaweb.cat) newswire.

#### Initial Data Collection and Normalization

12000 sentences from the BSC [Catalan Textual Corpus](https://doi.org/10.5281/zenodo.4519349), together with 6200 headers from the Catalan news site [VilaWeb](https://www.vilaweb.cat), were chosen randomly. We filtered them by different criteria, such as length and stand-alone intelligibility. For each selected text, we commissioned 3 hypotheses (one for each entailment category) to be written by a team of native annotators. 

Some sentence pairs were excluded because of inconsistencies. 

#### Who are the source language producers?

The Catalan Textual Corpus corpus consists of several corpora gathered from web crawling and public corpora. More information can be found [here](https://doi.org/10.5281/zenodo.4519349).

[VilaWeb](https://www.vilaweb.cat) is a Catalan newswire.

### Annotations

#### Annotation process

We commissioned 3 hypotheses (one for each entailment category) to be written by a team of annotators. 

#### Who are the annotators?

Annotators are a team of native language collaborators from two independent companies.

### Personal and Sensitive Information

No personal or sensitive information included.

## Considerations for Using the Data

### Social Impact of Dataset

We hope this dataset contributes to the development of language models in Catalan, a low-resource language.
