## 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:
- train_clean.ca: contains 9.692.996 Catalan sentences.
- train_clean.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](https://huggingface.co./PlanTL-GOB-ES/mt-plantl-es-ca).
**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.
