Model description

The roberta-base-bne-mldoc is a text classification model for the Spanish language fine-tuned from the roberta-base-bne model, a RoBERTa base model 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) from 2009 to 2019. The finetuning corpus consists of 14,458 news articles from Reuters classified in four categories: CCAT (Corporate/Industrial), ECAT (Economics), GCAT (Government/Social) and MCAT (Markets).

Intended uses and limitations

roberta-base-bne-mldoc model can be used to classify texts into four hierarchical groups: CCAT (Corporate/Industrial), ECAT (Economics), GCAT (Government/Social) and MCAT (Markets). The model is limited by its training dataset (news stories) and may not generalize well for all use cases.

How to use

Here is how to use this model:

from transformers import pipeline
from pprint import pprint

nlp = pipeline("text-classification", model="PlanTL-GOB-ES/roberta-base-bne-mldoc")
example = ' FRANCFORT, 17 feb (Reuter) - La Bolsa de Francfort abrió la sesión de corros con baja por la caída del viernes en Wall Street y una toma de beneficios.   El dólar ayudaba a apuntalar al mercado, que pronto podría reanudar su tendencia alcista.   Volkswagen bajaba por los daños ocasionados por la huelga de camioneros en España.   Preussag participaba en un joint venture de exploración petrolífera en Filipinas con Atlantic Richfield Co.   A las 0951 GMT, el Dax 30 bajaba 10,49 puntos, un 0,32 pct, a 3.237,69 tras abrir a un máximo de 3.237,69.   (c) Reuters Limited 1997. '

Limitations and bias

At the time of submission, no measures have been taken to estimate the bias 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.

Training

For training and evaluation we used the Spanish portion of the Multilingual Document Classification Corpus (MLDoc) (Schwenk and Li, 2018), a cross-lingual document classification dataset covering 8 languages.

Training procedure

The model was trained with a batch size of 32 and a learning rate of 1e-5 for 5 epochs. We then selected the best checkpoint using the downstream task metric in the corresponding development set and then evaluated it on the test set.

Evaluation

Variable and metrics

This model was finetuned maximizing F1.

Evaluation results

We evaluated the roberta-base-bne-mldoc on the XNLI test set against standard multilingual and monolingual baselines:

Model MLDoc (F1)
roberta-base-bne 96.64
roberta-large-bne 97.02
BETO 97.14
mBERT 96.17
BERTIN 96.68
ELECTRA 95.65
