bert-tweet-base-italian-uncased

This is a BERT [1] uncased model for the Italian language, obtained using TwHIN-BERT [2] (twhin-bert-base) as a starting point and focusing it on the Italian language by modifying the embedding layer (as in [3], computing document-level frequencies over the Wikipedia dataset)

The resulting model has 110M parameters, a vocabulary of 30.520 tokens, and a size of ~440 MB.

This model was trained on tweets, so it's mainly suitable for general-purpose social media text processing, involving short texts written in a social network style. It might show limitations when it comes to longer and more structured text, or domain-specific text.
