HateLab is a global hub for data and insight into hate speech and crime. We use data science methods, including ethical forms of AI, to measure and counter the problem of hate both online and offline. The Online Hate Speech Dashboard has been developed by academics with policy partners to provide aggregate trends over time and space. The Dashboard is being piloted within the National Online Hate Crime Hub, announced by the UK Home Secretary in 2017. We are funded by grants from the Economic and Social Research Council (ESRC), part of UK Research and Innovation (UKRI) and the US Department of Justice.
