Abstract

This article describes the system developed by the Grupode Tecnología del Habla at Universidad Politécnica de Madrid, Spain (GTH-UPM) for the competition on sentiment analysis in tweets: TASS2019. The developed system consisted of three classifiers: a) a systembased on feature vectors extracted from the tweets, b) a neural-based classifier using FastText, and c) a deep neural network classifier using contextual vector embeddings created using BERT. Finally, the averaged probabilities of the three classifiers were calculated to get the final score. The final system obtained an averaged F1 of 48.0% and 48.4% for the dev set on the mono and cross tasks respectively, 46.0% and 45.0% for the mono and cross tasks for the test set.
