Prof. Steffen Staab Delivers Keynote Address on Semantic Digital Twins at KGSWC 2023

November 8, 2023

KGSWC, an international scientific conference series devoted to knowledge graph and semantic web research, is set to take place from November 13 to November 15, 2023, in Zaragoza, Spain.
Prof. Dr. Steffen Staab will serve as a keynote speaker, addressing the audience on "Managing Identities, Changes, and Constraints for Semantic Digital Twins."
Here is the abstract of the talk:
A digital twin is a digital model of an intended or actual real-world physical product, system, or process that serves as a digital counterpart for purposes such as design, production, or operation. Because a digital twin must integrate the representation of many facets from its physical realization, semantic digital twins have been suggested to integrate data and concepts from many sources seamlessly.
Some semantic digital twins act as warehousing models providing life logs by only appending new information, e.g. new sensor readings, allowing for versatile access for purposes such as monitoring and predictive maintenance. Semantic digital twins for the design of products, such as customer goods, vehicles, or buildings, however, evolve through the interaction of a multitude of authorities over time. For example, in the excellence cluster “Integrative Computational Design and Construction of Architecture (IntCDC)”, we research how architects, structural engineers, acoustic designers, safety engineers, and others may collaborate to design and fabricate a building with many interdependencies whose ignoring may lead to severe issues concerning quality, scheduling, and costs.
In such scenarios, a knowledge graph cannot be a monolithic information construct. Rather, it consists of processing and programming pipelines between distributed authorities managing identities, change operations (including forgetting), and semantic constraints. In this talk, I plan to identify requirements and building blocks for representing and managing such semantic digital twins.
