 The corpus is a combination of the following original datasets collected from [Opus](https://opus.nlpl.eu/):
-CCMatrix, Multi CCAligned, WikiMatrix, GNOME, KDE 4, Open Subtitles.
+CCMatrix, MultiCCAligned, WikiMatrix, GNOME, KDE 4, Open Subtitles.
 
 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).
