Shining a light on dark jargon and countering hate speech

Suma Bhat

Abstract

Large and anonymous social platforms are a breeding ground for dark jargon and abusive language. A hallmark of the euphemisms and innuendos that abound in such language is non-compositionality. Large scale pretrained language models, generally successful on many canonical NLP tasks, perform very poorly in the presence of non-compositionality. In this talk, we discuss robust, largely unsupervised, methods to detect and interpret euphemisms in underground forums in a context-specific way. We also discuss robust mechanisms to generate counterspeech, bringing a computational lens to the active bystander-effect of social psychology. The key technical innovation is the use of novel language modeling mechanisms that do not explicitly rely on finetuning large scale pretrained language models.
