What is PERSEUS?

PERSEUS - Public Engagement for Responsive and Shared European Union Strategies - is an integrated toolkit for participatory and strategic decision-making at the EU level. It incorporates the various tools developed in WP5 and WP6 and will be tested during the deep dives in WP7. This tool will incorporate the AGGREGATOR database, the COCTEAU app, a module on AI-powered sentiment analysis, and the information and tools developed in all other WPs of the project.


The COCTEAU (Co-Creating the European Union) platform aims to be an experimental tool for public engagement. The development of COCTEAU will have as main partners a core team of POLIMI (leader), FRA, CEPS and ISINNOVA and will be tested within the Mission Oriented Innovation Policies of the EU.


The AGGREGATOR Database is the Atlas of Global Governance REGulation and Europe's AcTORness. The dataset contained in AGGREGATOR will be the result of the merging of two separate datasets, one on global governance and international regulatory cooperation developed in WP1 and the one on EU governance developed in WP2. The combined dataset will be integrated in a single software, which will incorporate a guided tool for the evaluation of EU actorness and influence.

The different sections of AGGREGATOR are:

  • Repository - A section of the platform allowing the visualization and filtering of the collected data (news, posts, etc.).
  • Media - A dashboard representing the outcomes of the analyses performed on the collection of news.
  • EUR-Lex - A collection of documents involving the European administration and laws.


The European Union focuses their efforts on specific use cases, e.g. COVID-19, SDGs (Sustainable Development Goals). This section of the platform allows the exploration of the data regarding a specific topic through a dedicated dashboard.
