A Platform Agnostic Dual-Strand Hate Speech Detector
Johannes Meyer, Björn Gambäck · 2019
Hate speech detectors must be applicable across a multitude of services and platforms, and there is hence a need for detection approaches that do not depend on any information specific to a given platform.For instance, the information stored about the text's author may differ between services, and so using such data would reduce a system's general applicability.The paper thus focuses on using exclusively text-based input in the detection, in an optimised architecture combining Convolutional Neural Networks and Long Short-Term Memory-networks.The hate speech detector merges two strands with character ngrams and word embeddings to produce the final classification, and is shown to outperform comparable previous approaches.
