## Overview |
|
- **Architecture:** roberta-base |
|
- **Language:** Spanish |
|
- **Task:** fill-mask |
|
- **Data:** BNE |
|
|
|
## Model Description |
|
RoBERTa-base-bne is a transformer-based masked language model for the Spanish language. It is based on the [RoBERTa](https://arxiv.org/abs/1907.11692) base model and has been pre-trained using the largest Spanish corpus known to date, with a total of 570GB of clean and deduplicated text processed for this work, compiled from the web crawlings performed by the [National Library of Spain (Biblioteca Nacional de España)](http://www.bne.es/en/Inicio/index.html) from 2009 to 2019. |
|
|
|
|
|
## Intended Uses and Limitations |
|
|
|
You can use the raw model for fill mask or fine-tune it to a downstream task. |
|
|
|
|
|
|
|
|
|
## How to Use |
|
You can use this model directly with a pipeline for fill mask. Since the generation relies on some randomness, we set a seed for reproducibility: |
|
|
|
```python |
|
>>> from transformers import pipeline |
|
>>> from pprint import pprint |
|
>>> unmasker = pipeline('fill-mask', model='PlanTL-GOB-ES/roberta-base-bne') |
|
>>> pprint(unmasker("Gracias a los datos de la BNE se ha podido <mask> este modelo del lenguaje.")) |
|
[{'score': 0.08422081917524338, |
|
'token': 3832, |
|
'token_str': ' desarrollar', |
|
'sequence': 'Gracias a los datos de la BNE se ha podido desarrollar este modelo del lenguaje.'}, |
|
{'score': 0.06348305940628052, |
|
'token': 3078, |
|
'token_str': ' crear', |
|
'sequence': 'Gracias a los datos de la BNE se ha podido crear este modelo del lenguaje.'}, |
|
{'score': 0.06148449331521988, |
|
'token': 2171, |
|
'token_str': ' realizar', |
|
'sequence': 'Gracias a los datos de la BNE se ha podido realizar este modelo del lenguaje.'}, |
|
{'score': 0.056218471378088, |
|
'token': 10880, |
|
'token_str': ' elaborar', |
|
'sequence': 'Gracias a los datos de la BNE se ha podido elaborar este modelo del lenguaje.'}, |
|
{'score': 0.05133328214287758, |
|
'token': 31915, |
|
'token_str': ' validar', |
|
'sequence': 'Gracias a los datos de la BNE se ha podido validar este modelo del lenguaje.'}] |
|
|
|
``` |
|
|
|
Here is how to use this model to get the features of a given text in PyTorch: |
|
|
|
```python |
|
>>> from transformers import RobertaTokenizer, RobertaModel |
|
>>> tokenizer = RobertaTokenizer.from_pretrained('PlanTL-GOB-ES/roberta-base-bne') |
|
>>> model = RobertaModel.from_pretrained('PlanTL-GOB-ES/roberta-base-bne') |
|
>>> text = "Gracias a los datos de la BNE se ha podido desarrollar este modelo del lenguaje." |
|
>>> encoded_input = tokenizer(text, return_tensors='pt') |
|
>>> output = model(**encoded_input) |
|
>>> print(output.last_hidden_state.shape) |
|
torch.Size([1, 19, 768]) |
|
``` |
|
|
|
## Limitations and bias |
|
|
|
At the time of submission, no measures have been taken to estimate the bias and toxicity embedded in the model. However, we are well aware that our models may be biased since the corpora have been collected using crawling techniques on multiple web sources. We intend to conduct research in these areas in the future, and if completed, this model card will be updated. Nevertheless, here's an example of how the model can have biased predictions: |
|
|
|
```python |
|
>>> from transformers import pipeline, set_seed |
|
>>> from pprint import pprint |
|
>>> unmasker = pipeline('fill-mask', model='PlanTL-GOB-ES/roberta-base-bne') |
|
>>> set_seed(42) |
|
>>> pprint(unmasker("Antonio está pensando en <mask>.")) |
|

|
|
|

|
## Training |
|
|
|
### Training Data |
|
|
|
The [National Library of Spain (Biblioteca Nacional de España)](http://www.bne.es/en/Inicio/index.html) crawls all .es domains once a year. The training corpus consists of 59TB of WARC files from these crawls, carried out from 2009 to 2019. |
|
|
|
To obtain a high-quality training corpus, the corpus has been preprocessed with a pipeline of operations, including among the others, sentence splitting, language detection, filtering of bad-formed sentences and deduplication of repetitive contents. During the process document boundaries are kept. This resulted into 2TB of Spanish clean corpus. Further global deduplication among the corpus is applied, resulting into 570GB of text. |
|
|
|
Some of the statistics of the corpus: |
|
|
|
| Corpora | Number of documents | Number of tokens | Size (GB) | |
|
|---------|---------------------|------------------|-----------| |
|
| BNE | 201,080,084 | 135,733,450,668 | 570GB | |
|
|
|
### Training Procedure |
|
The configuration of the **RoBERTa-base-bne** model is as follows: |
|
- RoBERTa-b: 12-layer, 768-hidden, 12-heads, 125M parameters. |
|
|
|
The pretraining objective used for this architecture is masked language modeling without next sentence prediction. |
|
The training corpus has been tokenized using a byte version of Byte-Pair Encoding (BPE) used in the original [RoBERTA](https://arxiv.org/abs/1907.11692) model with a vocabulary size of 50,262 tokens. |
|
The RoBERTa-base-bne pre-training consists of a masked language model training that follows the approach employed for the RoBERTa base. The training lasted a total of 48 hours with 16 computing nodes each one with 4 NVIDIA V100 GPUs of 16GB VRAM. |
