Start and end date

Start date:

July 2020.

End date:

June 2023.



Target group(s)

Federal and state police authorities.


National (Federal Ministry for Research and Education) – € 3 million.


  • Carry out research into the technical possibilities of artificial intelligence (AI) and ethical, legal and social framework conditions for responsible use of AI by police authorities to recognise, prevent and prosecute hate crime.
  • Classification of hate crime by AI according to the criminal code.
  • Classification of hate crime by topic.


  • Report (to be finalised in Q3 2023, plus annual intermediate reports).
  • Research papers.
  • Technical tool (prototype, to be finalised by Q2 2023).


In this research project, the use of AI to detect, prevent and prosecute hate crime in police organisations is being investigated within a holistic framework. Analysis of the organisational, ethical and legal framework necessary for the adoption of AI by the police to effectively prevent and prosecute hate crime is being undertaken. This framework, combined with the analysis of the effects of online hate crime on society, is used to define the technical conditions that are necessary for employing AI to classify hate speech according to:

  • the criminal code
  • the phenomena of hate speech
  • the topics of hate speech.

The aim of the project is to produce a number of reports that outline the necessary conditions to enable the police to adopt AI to counter hate crime, and investigate the necessary technical approach and potential solutions. The technical results will be demonstrated in a prototype that the police will evaluate. Together, these analyses can be used to implement AI as a supporting tool for the police to prevent, reduce and prosecute hate crime carried out on the internet.

Critical success factors

As the project has not yet been completed, an analysis of the critical success factors has not yet been undertaken.
