| ### EC40 is an English-Centric Multilingual Machine Translation Dataset. It has over 60 Million sentences including 40 Languages across 5 Language Families. | |
| #### Note: The dataset is cleaned and pre-processed using tools like Moses, for more details, please refer to the paper. | |
| ### Features: | |
| 1. We carefully balanced the dataset across resources and languages by strictly maintaining each resource group containing 5 language families and each family consists of 8 representative languages. | |
| 2. EC40 covers a wide spectrum of resource availability, ranging from High(5M) to Medium(1M), Low(100K), and extremely-Low(50K) resources. | |
| 3. In total, there are 80 English-centric directions for training and 1,640 directions (including all supervised and ZS directions) for evaluation. | |
| 4. We make use of Ntrex-128 and Flores-200 as our validation and test set. | |
