Chain of Explanation: New Prompting Method to Generate Higher Quality Natural Language Explanation for Implicit Hate Speech. (arXiv:2209.04889v1 [cs.CL])

Recent studies have exploited advanced generative language models to generate
Natural Language Explanations (NLE) for why a certain text could be hateful. We
propose the Chain of Explanation Prompting method, inspired by the chain of
thoughts study \cite{wei2022chain}, to generate high-quality NLE for implicit
hate speech. We build a benchmark based on the selected mainstream Pre-trained
Language Models (PLMs), including GPT-2, GPT-Neo, OPT, T5, and BART, with
various evaluation metrics from lexical, semantic, and faithful aspects. To
further evaluate the …
