# DictaBERT-Large: A State-of-the-Art BERT-Large Suite for Modern Hebrew

State-of-the-art language model for Hebrew, released [here](https://arxiv.org/abs/2308.16687).

This is the fine-tuned BERT-large model for the named-entity-recognition task.

For the bert-base models for other tasks, see [here](https://huggingface.co/collections/dicta-il/dictabert-6588e7cc08f83845fc42a18b).

For the bert-large models for other tasks, see [to-be-added].


Sample usage:

```python
from transformers import pipeline

oracle = pipeline('ner', model='dicta-il/dictabert-large-ner', aggregation_strategy='simple')

# if we set aggregation_strategy to simple, we need to define a decoder for the tokenizer. Note that the last wordpiece of a group will still be emitted
from tokenizers.decoders import WordPiece
oracle.tokenizer.backend_tokenizer.decoder = WordPiece()

sentence = '''דוד בן-גוריון (16 באוקטובר 1886 - ו' בכסלו תשל"ד) היה מדינאי ישראלי וראש הממשלה הראשון של מדינת ישראל.'''
oracle(sentence)
```

Output:
```json
[
  {
    "entity_group": "PER",
    "score": 0.9998988,
    "word": "דוד בן - גוריון",
