The aim is to develop

  1. elaborated and tested instruments for the identification of non-journalistic providers with political relevance,
  2. procedures for the automated estimation of opinion power and diversity measurement in the area of ​​intermediaries,
  3. and resulting recommendations for a contemporary regulation of media opinion power.
