We extract article and summary pairs in 18 languages from WikiHow, a high quality, collaborative resource of how-to guides on a diverse set of topics written by human authors. We create gold-standard article-summary alignments across languages by aligning the images that are used to describe each how-to step in an article. As a set of baselines for further studies, we evaluate the performance of existing cross-lingual abstractive summarization methods on our dataset. We further propose a method for direct cross-lingual summarization (i.e., without requiring translation at inference time) by leveraging synthetic data and Neural Machine Translation as a pre-training step. Our method significantly outperforms the baseline approaches, while being more cost efficient during inference.", }

Dataset Structure

Data Fields

List and describe the fields present in the dataset.

gem_id -- The id for the data instance. source_language -- The language of the source article. target_language -- The language of the target summary. source -- The source document.

Example Instance

Provide a JSON formatted example of a typical instance in the dataset.

{ "gem_id": "wikilingua_crosslingual-train-12345", "gem_parent_id": "wikilingua_crosslingual-train-12345", "source_language": "fr", "target_language": "de", "source": "Document in fr", "target": "Summary in de", }

Data Splits

Describe and name the splits in the dataset if there are more than one.

The data is split into train/dev/test. In addition to the full test set, there's also a sampled version of the test set.

Splitting Criteria

Describe any criteria for splitting the data, if used. If there are differences between the splits (e.g., if the training annotations are machine-generated and the dev and test ones are created by humans, or if different numbers of annotators contributed to each example), describe them here.

The data was split to ensure the same document would appear in the same split across languages so as to ensure there's no leakage into the test set.

  • Getting Started with the Task

Rationale for Inclusion in GEM

Why is the Dataset in GEM?

What does this dataset contribute toward better generation evaluation and why is it part of GEM?

This dataset provides a large-scale, high-quality resource for cross-lingual summarization in 18 languages, increasing the coverage of languages for the GEM summarization task.

Similar Datasets

Do other datasets for the high level task exist?

yes

Unique Language Coverage

Does this dataset cover other languages than other datasets for the same task?

yes

Difference from other GEM datasets

What else sets this dataset apart from other similar datasets in GEM?

XSum covers English news articles, and MLSum covers news articles in German and Spanish. In contrast, this dataset has how-to articles in 18 languages, substantially increasing the languages covered. Moreover, it also provides a a different domain than the other two datasets.

Ability that the Dataset measures

What aspect of model ability can be measured with this dataset?

The ability to generate quality summaries across multiple languages.

GEM-Specific Curation

Modificatied for GEM?

Has the GEM version of the dataset been modified in any way (data, processing, splits) from the original curated data?

yes

GEM Modifications

What changes have been made to he original dataset?

other

Modification Details

For each of these changes, described them in more details and provided the intended purpose of the modification

Previous version had separate data loaders for each language. In this version, we've created a single monolingual data loader, which contains monolingual data in each of the 18 languages. In addition, we've also created a single cross-lingual data loader across all the language pairs in the dataset.

Additional Splits?

Does GEM provide additional splits to the dataset?

no

Measured Model Abilities

What aspect of model ability can be measured with this dataset?

Ability to summarize content across different languages.

Metrics

What metrics are typically used for this task?

ROUGE

Proposed Evaluation

List and describe the purpose of the metrics and evaluation methodology (including human evaluation) that the dataset creators used when introducing this task.

ROUGE is used to measure content selection by comparing word overlap with reference summaries. In addition, the authors of the dataset also used human evaluation to evaluate content selection and fluency of the systems.

Original curation rationale

The dataset was created in order to enable new approaches for cross-lingual and multilingual summarization, which are currently understudied as well as open up inetersting new directions for research in summarization. E.g., exploration of multi-source cross-lingual architectures, i.e. models that can summarize from multiple source languages into a target language, building models that can summarize articles from any language to any other language for a given set of languages.
