## BART Legal Spanish ⚖️

**BART Legal Spanish** (base) is a BART-like model trained on [A collection of corpora of Spanish legal domain](https://zenodo.org/record/5495529#.YZItp3vMLJw).

BART is a transformer *encoder-decoder* (seq2seq) model with a bidirectional (BERT-like) encoder and an autoregressive (GPT-like) decoder. BART is pre-trained by (1) corrupting text with an arbitrary noising function and (2) learning a model to reconstruct the original text.

This model is particularly effective when fine-tuned for text generation tasks (e.g., summarization, translation) but also works well for comprehension tasks (e.g., text classification, question answering).



## Training details

- Dataset: `Spanish-legal-corpora` - 90% for training / 10% for validation.
- Training script: see [here](https://github.com/huggingface/transformers/blob/main/examples/flax/language-modeling/run_bart_dlm_flax.py)

## How to use with `transformers`

```py
from transformers import BartForConditionalGeneration, BartTokenizer

model_id = "mrm8488/bart-legal-base-es"

model = BartForConditionalGeneration.from_pretrained(model_id, forced_bos_token_id=0)
tokenizer = BartTokenizer.from_pretrained(model_id)

def fill_mask_span(text):
  batch = tokenizer(text, return_tensors="pt")
  generated_ids = model.generate(batch["input_ids"])
  print(tokenizer.batch_decode(generated_ids, skip_special_tokens=True))

text = "Los españoles son <mask> ante la ley."
fill_mask_span(text)
# Output: ['Los españoles son iguales ante la ley.1.ª y 2.ª ante la']

text = "Los proyectos de reforma Constitucional deberán <mask> por una mayoría de tres quintos de cada una de las Cámaras."
fill_mask_span(text)
# Output: ['Los proyectos de reforma Constitucional deberán ser aprobados por una mayoría de tres quintos de cada']

```
