Model description

The roberta-large-bne-massive is a Intent Classification model for the Spanish language fine-tuned from the roberta-large-bne-massive model, a RoBERTa based model pre-trained on a medium-size corpus collected from publicly available corpora and crawlers.

The model uses MASSIVE 1.1, a parallel dataset of > 1M utterances across 52 languages with annotations for the Natural Language Understanding tasks of intent prediction and slot annotation. Utterances span 60 intents and include 55 slot types.

Intended uses and limitations

The roberta-large-bne-massive model can be used for intent prediction in plain text sentences in Spanish. It can be used in combination with an Automatic Speech Recognition model in order to implement a Voice Assistant. The model is limited by its training dataset 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-large-bne-massive")
example = "m'agraden les cançons del serrat"

intent = nlp(example)
pprint(intent)

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 used the Spanish split of the MASSIVE dataset for training and evaluation.

Training procedure

The model was trained with a batch size of 16 and a learning rate of 1e-5 for 20 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 roberta-large-bne-massive on the MASSIVE test set obtaining a weighted F1 score of 87.27.
