Dataset Description

Dataset Summary

The CA-EU Parallel Corpus is a Catalan-Basque synthetic dataset of 9.692.996 parallel sentences. The dataset was created to support Catalan NLP tasks, e.g., Machine Translation.

Supported Tasks and Leaderboards

The dataset can be used to train a model for Multilingual Machine Translation. Success on this task is typically measured by achieving a high BLEU score.

Languages

The texts in the dataset are in Catalan and Basque.

Dataset Structure

Two separated txt files are provided with the sentences sorted in the same order:

• xxx.ca: contains 9.692.996 Catalan sentences.

• xxx.eu: contains 9.692.996 Basque sentences.

Data Splits

The dataset contains a single split: train.

Dataset Creation

Source Data

This synthetic dataset was created in the frame of Project Ilenia. An authentic parallel corpus ES-EU was delivered by Project GAITU and the Spanish was translated to Catalan using the machine translation model PlanTL-GOB-ES.

Total: 9.692.996 parallel sentences .

Personal and Sensitive Information

No anonymisation process was performed.

Considerations for Using the Data

Social Impact of Dataset

The purpose of this dataset is to help develop Machines Translation tasks for low-resource languages such as Catalan.

Discussion of Biases

We are aware that since part of the data comes from unreliable web pages and non-curated texts, some biases may be present in the dataset. Nonetheless, we have not applied any steps to reduce their impact.

Other Known Limitations

The dataset contains data of a general domain. Application of this dataset in more specific domains such as biomedical, legal etc. would be of limited use.
