UmBERTo Commoncrawl Cased

UmBERTo is a Roberta-based Language Model trained on large Italian Corpora and uses two innovative approaches: SentencePiece and Whole Word Masking. Now available at github.com/huggingface/transformers

Marco Lodola, Monument to Umberto Eco, Alessandria 2019

Dataset

UmBERTo-Commoncrawl-Cased utilizes the Italian subcorpus of OSCAR as training set of the language model. We used deduplicated version of the Italian corpus that consists in 70 GB of plain text data, 210M sentences with 11B words where the sentences have been filtered and shuffled at line level in order to be used for NLP research.

Pre-trained model

This model was trained with SentencePiece and Whole Word Masking.

Downstream Tasks

These results refers to umberto-commoncrawl-cased model. All details are at Umberto Official Page.

Usage

import torch
from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("Musixmatch/umberto-commoncrawl-cased-v1")
umberto = AutoModel.from_pretrained("Musixmatch/umberto-commoncrawl-cased-v1")

encoded_input = tokenizer.encode("Umberto Eco è stato un grande scrittore")
input_ids = torch.tensor(encoded_input).unsqueeze(0)  # Batch size 1
outputs = umberto(input_ids)
last_hidden_states = outputs[0]  # The last hidden-state is the first element of the output

from transformers import pipeline

fill_mask = pipeline(
    "fill-mask",
    model="Musixmatch/umberto-commoncrawl-cased-v1",
    tokenizer="Musixmatch/umberto-commoncrawl-cased-v1"
)

result = fill_mask("Umberto Eco è <mask> un grande scrittore")
