DictaBERT-splinter: Splintering Nonconcatenative Languages for Better Tokenization

DictaBERT-splinter is a BERT-style language model for Hebrew, released here.

This is the base model pretrained with the masked-language-modeling objective.

Sample usage:

from transformers import AutoModelForMaskedLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained('dicta-il/dictabert-splinter', trust_remote_code=True)
model = AutoModelForMaskedLM.from_pretrained('dicta-il/dictabert-splinter')

model.eval()

sentence = 'בשנת 1948 השלים אפרים קישון את [MASK] בפיסול מתכת ובתולדות האמנות והחל לפרסם מאמרים הומוריסטיים'

output = model(tokenizer.encode(sentence, return_tensors='pt'))
# the [MASK] is the 7th token (including [CLS])
import torch
top_2 = torch.topk(output.logits[0, 7, :], 2)[1]
print('\n'.join(tokenizer.batch_decode(top_2))) # should print התמחותו / לימודיו
