### Dataset Summary |
|
|
|
The CA-PT Parallel Corpus is a Catalan-Portuguese dataset of 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. The dataset can be used to finetune a large-scale multilingual MT system such as m2m-100. |
|
|
|
### Languages |
|
|
|
The texts in the dataset are in Catalan and Portuguese. |
|
|
|
## Dataset Structure |
|
|
|
Two separated txt files are provided with sentences in the same order. |
|
|
|
### Data Splits |
|
|
|
The dataset contains a single split: `train`. |
|
|
|
## Dataset Creation |
|
|
|
All datasets are deduplicated and filtered to remove any sentence pairs with a cosine similarity of less than 0.75. This is done using sentence embeddings calculated using [LaBSE](https://huggingface.co/sentence-transformers/LaBSE). The filtered datasets are then concatenated to form a final corpus of 6.159.631 and before training the punctuation is normalized using a modified version of the join-single-file.py script from [SoftCatalà](https://github.com/Softcatala/nmt-models/blob/master/data-processing-tools/join-single-file.py) |

### Source Data |
|
|
|
### 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. |
