When we relaunched Hatebase at the end of last year, we deployed not only a wealth of new data attributes (e.g. targeted groups, plurals, transliterations) and a new API (now v4.1); we also included a complete bottom-up rebuild of HateBrain, the natural language processing (NLP) engine at the heart of Hatebase, which is responsible for (as of this month) 738,000 regionalized, timestamped hate speech sightings.
