Title: Semantic modeling and analysis of complex data-aware processes and their executions
Abstract: The worlds of Business Process Management (BPM) and Process Mining has had only few connections with those of Knowledge Management and Semantic Web. Indeed their intersections amounted in few attempts to model semantic business processes or exploit ontologies, such as the BPMN ontology, to reason on semantically enriched process models. One of the reasons of this distance might lie in the fact that the business process oriented communities were mainly focused on handling temporally oriented entities such as activities and their temporal (work)flows relations, while the knowledge oriented ones were mainly focused on the modelling and handling of static entities and relations. In the last few years nonetheless the two groups have started expanding their interests and this may end up in better connecting with each others. Indeed, the business process communities have started looking more and more towards multi-dimensional processes, characterised by a complex network of entities that go beyond the typical event-based ones and include data objects, resources, actors, goals, among others. At the same time the knowledge oriented one has shown a growing interest in temporally denoted entities such as events, stories and narratives. In this talk I will use some of our works on Semantic Modelling and Analysis of Complex Data-aware Processes and their Executions to try to highlight possible connections between these two worlds and by showing how OWL knowledge bases can be used to model and query not only Data-aware Processe models but also process executions. Moreover I will introduce the new concept of Knowledge Event Graphs so as to highlight how semantically enriched graphs could provide benefits to the BPM community.

Title: Semantic Foundations of Dataspaces: Insights from Gaia-X and the IDS
Abstract: Digital transformation is rapidly changing the way we work and live. Data has emerged as a driver of innovation, enabling organizations to gain insights, make decisions and create competitive advantage. The need to maintain control over data as it is shared is being addressed by dataspaces, funded by the EU with €4-6 billion. In this talk, we evaluate the potential of semantics as a building block for dataspaces, share insights from Gaia-X and the International Data Spaces, and motivate future collaboration to overcome current limitations.
Title: The Web and Linked Data as a Solid Foundation for Dataspaces
Abstract: The concepts for dataspaces range from database management systems to cross-company platforms for data and applications. In this short paper, we present the “Solid Data Space” (SDS), a concept for dataspaces that build on top of the (Semantic) Web and Social Linked Data (Solid). Existing Web technologies and Linked Data principles form the foundation for open, decentralized networks for sovereign data exchange between citizens, organizations, and companies. Domain-specific dataspace implementations can extend the agreements for communication and collaboration to enable specific functionality. We compare the SDS with principles and components of the emerging International Data Spaces to identify similarities and point out technological differences.
Title: Overview of Data Ecosystems
Abstract: Data-driven innovation has recently changed the mindset in data sharing from centralized architectures and monolithic exploitation of data by data providers (data platforms) to decentralized architectures and different data sharing options among all involved participants (data ecosystems). Collaborative data sharing is strengthened through the establishment of several legal frameworks (e.g., European Strategy for Data, Data Act, Data Governance Act) and emerging technical initiatives providing the means to build data ecosystems (DEs). However, the differences between them are not clear, making it hard to choose the most suitable for each scenario, and, thus, impacting negatively their adoption. Since the domain is growing fast, there is a need of a review of the state-of-the-art DE initiatives. In this presentation we will review the state of the art in DE initiatives, describe their innovative aspects, compare them through a technical and business comparison, identify common features and practises and finally identify open challenges.
