Data ecosysworkshop. tems (DEs) are the future of data management since they allow companies to share data and collaborate to get valuable insights. Such benefits can be achieved only with a proper approach for generating and sharing knowledge.
Thus, DEs aim to solve issues like managing unstructured and heterogeneous data, ofering various data-centric services, including query processing and data analytics, and exchanging and integrating data while preserving personal data privacy, security, and organizational data sovereignty. Hence, to implement a data ecosystem, manifold challenges regarding, amongst others, data management, data quality, trust, data exchange, data integration, machine learning, or knowledge-based systems have to be solved and integrated. In the Second International Workshop on Data Ecosystems (DEco’23), we aimed to publish innovative contributions addressing such challenges.
From the submissions, we could accept 3 high-quality full papers. The accepted papers comprise aspects of data sharing, trust, federated machine learning and repositories, and report experiences from use cases based on data ecosystems.
The workshop is organized around two paper presentation sessions. We are delighted to count on Prof. Mathias Jarke from RWTH Aachen University and the Fraunhofer Institute for Applied Information Technology FIT for an inspiring keynote talk reporting experiences of the ”Data
