# Spanish BERT (BETO) + POS |
|
|
|
This model is a fine-tuned on Spanish [CONLL CORPORA](https://www.kaggle.com/nltkdata/conll-corpora) version of the Spanish BERT cased [(BETO)](https://github.com/dccuchile/beto) for **POS** (Part of Speech tagging) downstream task. |
|
|
|
## Details of the downstream task (POS) - Dataset |
|
|
|
- [Dataset: CONLL Corpora ES](https://www.kaggle.com/nltkdata/conll-corpora) with data augmentation techniques |
|
|
|
I preprocessed the dataset and split it as train / dev (80/20) |
|
|
|
| Dataset | # Examples | |
|
| ---------------------- | ----- | |
|
| Train | 340 K | |
|
| Dev | 50 K | |

|
|
|
```python |
|
from transformers import pipeline |
|
|
|
nlp_pos = pipeline( |
|
"ner", |
|
model="mrm8488/bert-spanish-cased-finetuned-pos", |
|
tokenizer=( |
|
'mrm8488/bert-spanish-cased-finetuned-pos', |
|
{"use_fast": False} |
|
)) |
|
|
|
|
|
text = 'Mis amigos están pensando en viajar a Londres este verano' |
|
|
