<h3>Model description</h3>

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

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

<h3>Quick usage</h3>

from transformers import BertTokenizerFast, BertModel

tokenizer = BertTokenizerFast.from_pretrained("osiria/bert-tweet-base-italian-uncased")
model = BertModel.from_pretrained("osiria/bert-tweet-base-italian-uncased")

<h3>Limitations</h3>

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.
