Health research, medical practice and consequently the whole population is increasingly affected by digitization, data science and AI.

Patients share valuable advice and experiences with their peers in online patient discussion groups.

The archaeology domain produces large amounts of texts, too much to effectively read or manually search through for research. To alleviate this problem, we created a search system (called AGNES), which combines full text search with entity and geographical search.

It is integral to many cluster members’ research to use Medieval and Early Modern Arts as a lens for studying the medieval and early modern periods at large:
