Hateful content online is a growing problem in the UK. It can pollute civic discourse, inflict harm on targeted victims, create and exacerbate social divisions, and erode trust in the host platforms. This project is developing and applying advanced computational methods to systematically measure, analyse and counter hate speech across different online domains, including social media and news platforms.
Explaining the science
This research is using advanced computational methods, including supervised machine learning, stochastic modelling and natural language processing, to detect and analyse hate speech. Initial research is aimed at developing supervised machine learning classifiers to detect and categorise different strengths and targets of hate speech.
The aim is to understand the scale and scope of online hateful content, taking into account its different forms, from ‘everyday’ subtle actions to overt acts of aggression and criminality, and the different targets, such as ethnic minorities and women. The project also aims to understand the dynamics and drivers of hate, providing granular insight into when, where and why it manifests.
The tools being developed for automatically identifying and categorising hateful content will be of interest to government, policymakers, companies, and other researchers. The project researchers will work across stakeholders to establish best practices, share findings and offer insight. The code and data involved our being made as accessible as possible and the researchers will be blogging about their work as the project progresses.
