Tokenization: A Survey for Modern NLP [R]

Excerpt

Tokenization is a wildly understudied area of language modeling despite it having effects across all of NLP. Over the past ~8 months, 32 (!) tokenizer researchers put together the most comprehensive survey of the field. We cover every aspect of tokenization: algorithms, evaluations, multilinguality, encodings, theory, etc. We even cover what you might want to replace tokenizers with (e.g., latent or visual tokenization). We also cover some topics that are closely adjacent to tokenization, such a
