-Catalan-Basque data collected from the web ([Opus](https://opus.nlpl.eu/)): 1.045.677 sentences.
+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).

-### 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).
