+## Updates/Notes:
 1. New datasets is added for the evaluation (e.g. [arabic-quotes](https://huggingface.co/datasets/HeshamHaroon/arabic-quotes), [Moroccan_Arabic_Wikipedia_20230101_nobots](https://huggingface.co/datasets/SaiedAlshahrani/Moroccan_Arabic_Wikipedia_20230101_nobots)).
 1. `Fertility Score` is calculated by dividing the total number of tokens by the total number of words in the dataset (Lower is better).
 1. `Tokenize Tashkeel` is an indicator of whether the tokenizer maintains the tashkeel when tokenizing or not (`✅` for yes, `❌` for no).
 1. `Vocab Size` is the total number of tokens in the tokenizer's vocabulary (e.g. `10000` tokens).
 1. `Tokenizer Class` is the class of the tokenizer (e.g. `BertTokenizer` or `GPT2Tokenizer`)
 1. `Total Number of Tokens` is the total number of tokens in the dataset after tokenization (Lower is better).
