| ## Dataset Description |
|
|
| ### Dataset Summary |
|
|
| The CA-GL Parallel Corpus is a Catalan-Galician synthetic dataset of **33.668.599** 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 Galician. |
|
|
| ## Dataset Structure |
|
|
| Two separated txt files are provided with the sentences sorted in the same order: |
|
|
| - nos_all.ca: contains 33.668.599 Catalan sentences (synthetic). |
| |
| - nos_all.gl: contains 33.668.599 Galician sentences (authentic). |
|
|
| ### 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-GL was delivered by Proxecto Nós |
| 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: 33.668.599 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. |
