Reducing social biases in text-based emotion prediction using semantic blinding and semantic propagation graph neural networks (opens in new tab)

This paper introduces the Semantic Propagation Graph Neural Network (SProp GNN), a machine learning emotion prediction (EP) architecture that relies exclusively on syntactic structures and word-level emotional cues to predict emotions in text. By semantically blinding the model to information about specific words, it is robust to social biases such as political or gender bias that have been plaguing previous machine learning-based EP systems. The SProp GNN shows performance superior to lexico...
