Data Week is the spring gathering of the European Big Data and Data Driven AI research and innovation communities, where the participants share knowledge and results, discuss topics of common interest, find synergies, build new collaborations and identify new challenges and recommendations. Data Week is co-organized by Big Data Value Association and the EUHubs4Data project. This year’s main theme was “Towards an innovative, trusted and fair European data economy”.

The session explored the latest EU research outcomes related to Extreme Data Analytics applications in smart cities, healthcare, robotics, and the maritime industry. The participants focused on the key challenges addressed in each sector in an effort to showcase the lessons they learned the hard way and encourage other researchers to take them into consideration.
