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?" by Yin et al. (2021), and an original version of the corpus is hosted on Github 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 script for more details).

Supported Tasks and Leaderboards

Machine Translation

Refer to the original paper 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 corpus and translated into the French (fr)

Dataset Structure

Data Instances

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

{
  "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 it 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 plantes , et je leur ai donné de l'eau et du soleil.",
  "fr": "Mais j'ai donné une attention particulière à une pour voir si elle grandit plus.",
  "contrast_fr": "Mais j'ai donné une attention particulière à une pour voir si il grandit plus.",
  "context_en_with_tags": "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_with_tags": "But I gave one special attention to see if <p>it</p> would grow more.",
  "context_fr_with_tags": "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_with_tags": "Mais j'ai donné une attention particulière à une pour voir si <p>elle</p> grandit plus.",
  "contrast_fr_with_tags": "Mais j'ai donné une attention particulière à une pour voir si <p>il</p> grandit plus.",
  "has_supporting_context": true,
}

In every example, the pronoun of interest and its translation are surrounded by ... tags. These are guaranteed to be found in the en_with_tags and fr_with_tags 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.

Fields with the _with_tags suffix contain tags around pronouns of interest and supporting context, while their counterparts without the suffix contain the same text without tags, to facilitate direct usage with machine translation models.

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	10638
`validation`	145	142
`test`	1000	962

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.

Please refer to the original article Do Context-Aware Translation Models Pay the Right Attention? for additional information on dataset creation.

Additional Preprocessing

Compared to the original SCAT corpus, the following differences are present in this version:

Examples were filtered using the filter_scat.py script to retain only examples containing well-formed tags, and remove superfluous tags. Superfluous tags are defined as nested <hon>...<hoff> tags that represent lack of contextual information for disambiguating the correct pronoun. In this case, the outer <hon>...<hoff> tag was removed. We also filter examples that do not contain tags for the pronoun on interest in the target sentence for English and French (en, fr).
Sentences stripped from tags are provided in fields without the _with_tags suffix.
Tags erroneously embedded within words of target sentence (e.g. just sitting there, waiting for his face) were removed.
An extra contrastive sentence using the pronoun of interest belonging to the opposite gender is available in the contrast_fr field. The swap was performed using a simple lexical heuristic (refer to swap_pronoun in scat.py), and we do not guarantee grammatical correctness of the sentence.
