Abstract

In this paper, we describe our submissions for PAN at CLEF 2021 contest. We tackled the subtask “Profiling Hate Speech Spreaders on Twitter”. We developed different models for English and Spanish languages, using classic machine learning methods like Support Vector Classifier, Multi-Layer Perceptron, Logistic Regression, Random Forest, Ada-Boost Classifier and K-Neighbors Classifier to more recent deep learning methods like BERT and Bidirectional LSTM.
