### Dataset Summary

The Supporting Context for Ambiguous Translations corpus (SCAT) is a dataset of English-to-French translations annotated with human rationales used for resolving ambiguity in pronoun anaphora resolution for multi-sentence translation.

**Disclaimer**: *The SCAT corpus was released in the ACL 2021 paper ["Do Context-Aware Translation Models Pay the Right Attention?"](https://aclanthology.org/2021.acl-long.65/) by Yin et al. (2021), and an original version of the corpus is hosted on [Github](https://github.com/neulab/contextual-mt/tree/master/data/scat) with no licensing information. This dataset contains a curated version of the original corpus where examples containing nested or malformed tags were removed (refer to the [filter_scat.py](filter_scat.py) script for more details).*

### Supported Tasks and Leaderboards
#### Machine Translation
Refer to the [original paper](https://aclanthology.org/2021.acl-long.65/) for additional details on plausibility evaluation for document-level MT systems.
### Languages
The dataset contains source English sentences containing anaphoric pronouns selected from the [OpenSubtitles 2018](https://www.aclweb.org/anthology/L18-1275/) corpus and translated into the French (`fr`)
## Dataset Structure
### Data Instances

The dataset contains a single default configuration. Dataset examples have the following format:

```json
{
  "id": 0,
  "context_en": "Air, water, the continents. So, what is your project about and what are its chances of winning? - Well, my project is awesome. - Oh, good. I took two plants, and I gave them sun and water",
  "en": "But I gave one special attention to see if <p>it</p> would grow more.",
  "context_fr": "L'air, l'eau, les continents. Donc, quel est le sujet de ton projet et quelles sont ses chances de gagner ? - Bien, mon projet est impressionnant. - Oh, bien. J'ai pris deux <hon>plantes<hoff> , et je leur ai donné de l'eau et du soleil.",
  "fr": "Mais j'ai donné une attention particulière à une pour voir si <p>elle</p> grandit plus.",
  "has_supporting_context": true,
}
```

In every example, the pronoun of interest and its translation are surrounded by `<p>...</p>` tags. These are guaranteed to be found in the `en` and `fr` field, respectively.

Any span surrounded by `<hon>...<hoff>` tags was identified by human annotators as supporting context to correctly translate the pronoun of interest. These spans can be missing altogether (i.e. no contextual information needed), or they can be found in any of the available fields. The `has_supporting_context` field indicates whether the example contains any supporting context.

In the example above, the translation of the pronoun `it` (field `en`) is ambiguous, and the correct translation to the feminine French pronoun `elle` (in field `fr`) is only possible thanks to the supporting feminine noun `plantes` in the field `context_fr`. Since the example contains supporting context, the `has_supporting_context` field is set to `true`.

### Data Splits

The dataset is split into `train`, `validation` and `test` sets. In the following table, we report the number of examples in the original dataset and in this filtered version in which examples containing malformed tags were removed.

| Split         | # Examples (original) | # Examples (**this**) |
| :-----------: | :-------------------: | :-------------------: |
| `train`       |    11471              |    11144              |
| `validation`  |    145                |    144                |
| `test`        |    1000               |    973                |

### Dataset Creation

From the original paper:

>We recruited 20 freelance English-French translators on Upwork. We annotate examples from the contrastive test set by Lopes et al. (2020). This set includes 14K examples from the OpenSubtitles2018 dataset. Through our annotation effort, we obtain 14K examples of supporting context for pronoun anaphora resolution in ambiguous translations selected by professional human translators.
