Centre for Corpus Approaches to Social Science (CASS) is a centre designed to bring a new method in the study of language - the corpus approach - to a range of social sciences. In doing so it provides an insight into the use and manipulation of language in society in a host of areas of pressing concern, including climate change, hate crime and education. By providing fresh perspectives on such problems, we are helping to develop new approaches to challenging practices such as hate speech both in terms of raising awareness and of informing policymakers and other stakeholders of how such language may be used to wound and offend.
