Model description

The Controversy Prediction model is a RoBERTa-base model trained of a dataset of news from the platform Menéame annotated with controversy tags in a community-based manner.

Intended uses and limitations

The Controversy Prediction model can be used for controversy prediction in news in Spanish.

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/Controversy-Prediction")
example = "Esposas, hijos, nueras y familiares de altos cargos del PP y de la cúpula universitaria llenan la URJC -- Pedro González-Trevijano, rector de la universidad desde 2002 a 2013, ahora magistrado del Tribunal Constitucional, y su sucesor en el cargo, Fernando Suárez han tejido una red que ha dado cobijo laboral a más de un centenar de familiares de vicerrectores, gerentes o catedráticos en los cuatro campus con los que cuenta la universidad localizados en Alcorcón, Móstoles, Fuenlabrada y Vicálvaro."

output = nlp(example)
pprint(output)

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

Training data

We use a dataset of news from the Menéame platform, tagged with controversy labels in a community-based manner. The training set contains 18,270 news, from which 4,950 are controversial. The development set contains 1,058 news, from which 317 are controversial.

Training procedure

The model was trained with a batch size of 4 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 the weighted F1 score.

Evaluation results

We evaluated the Controversy-Prediction model on the Menéame test set obtaining a weighted F1 score of 84.72. The test set contains 1,058 news, from which 317 are controversial.
