Dataset Card for ES-AN Parallel Corpus
Dataset Description
- Point of Contact: langtech@bsc.es
Dataset Summary
The ES-AN Parallel Corpus is a Spanish-Aragonese dataset created to support the use of under-resourced languages from Spain, such as Aragonese, in NLP tasks, specifically Machine Translation.
Supported Tasks and Leaderboards
The dataset can be used to train Bilingual Machine Translation models between Aragonese and Spanish in any direction, as well as Multilingual Machine Translation models.
Languages
The sentences included in the dataset are in Spanish (ES) and Aragonese (AN).
Dataset Structure
Data Instances
Two separate txt files are provided:
- es-an_corpus.es
- es-an_corpus.an
The dataset is additionally provided in parquet format: es-an_corpus.parquet.
The parquet file contains two columns of parallel text obtained from the two original text files. Each row in the file represents a pair of parallel sentences in the two languages of the dataset.
Data Fields

Data Splits
The dataset contains a single split: train.
Dataset Creation
Curation Rationale
This dataset is aimed at promoting the development of Machine Translation between Spanish and under-resourced languages from Spain, specifically Aragonese.
Source Data
Initial Data Collection and Normalization
This dataset was created as part of the participation of Language Technologies Unit at BSC in the WMT24 Shared Task: Translation into Low-Resource Languages of Spain. The corpus is the result of a thorough cleaning and preprocessing, as described in detail in the paper "Training and Fine-Tuning NMT Models for Low-Resource Languages using Apertium-Based Synthetic Corpora". As no filtering based on alignment score was applied, the dataset may contain poorly aligned sentences.
This dataset is mainly synthetic, generated using the rule-based translator Apertium. It contains synthetic Spanish, derived from the Aragonese PILAR monolingual dataset. It also includes synthetic Aragonese, obtained by translating the Spanish side of the Spanish-Aragonese pairs from OPUS. Additionally, it contains synthetic Spanish translated from monolingual Aragonese text extracted from the document ortografia-aragones.pdf, provided by the organizers.

Personal and Sensitive Information
Given that this dataset is partly derived from pre-existing datasets that may contain crawled data, and that no specific anonymisation process has been applied, personal and sensitive information may be present in the data. This needs to be considered when using the data for training models.
Considerations for Using the Data
Social Impact of Dataset
By providing this resource, we intend to promote the use of Aragonese across NLP tasks, thereby improving the accessibility and visibility of the Aragonese language.
Discussion of Biases
No specific bias mitigation strategies were applied to this dataset. Inherent biases may exist within the data.
Other Known Limitations
The dataset contains data of a general domain. Applications of this dataset in more specific domains such as biomedical, legal etc. would be of limited use.
