+## Dataset Description
+
+### Dataset Summary
+
+The CA-GL Parallel Corpus is a Catalan-Galician dataset of **123.890.107** 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 XXX Catalan sentences.
+
+- xxx.gl: contains XXX Galician sentences.
+
+### Data Splits
+
+The dataset contains a single split: `train`.
+
+## Dataset Creation
+
+### Source Data
+
+Catalan-Galician data collected from the web ([Opus](https://opus.nlpl.eu/)): 4.267.995 sentences.
+
+Synthetic parallel data created in the frame of Project Ilenia by machine translating the parallel corpora ES-GL from NÓS: 33.668.599 sentences.
+
+Synthetic parallel data created in the frame of Project Ilenia by machine translating the parallel corpora ES-CA from AINA: 85.953.513 sentences.
+
+**Total: 123.890.107 parallel sentences** .
+
+### Data preparation
+
+ 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).
+
+### 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.
