Special Interest Group on Languages, Logic, and Ontologies for DT design, interoperability, and analysis (SIG LLODIA)

Upcoming Event

We’re excited to announce our Inaugural SIG LLODIA Lecture as part of the SIG LLODIA series. Details below:



Event Title Inaugural SIG LLODIA Lecture: Ontology in Digital Twins – Exploring Semantic Interoperability and Systemic Connections
Date and time 23 May 2025, 2.30pm to 4pm
Speaker Mark Enzer OBE FREng
Mark is a keen champion of outcomes-focused systems-thinking, collaborative delivery models, digitalisation, connected digital twins and the circular economy in the built environment. Mark is the Royal Academy of Engineering Visiting Professor in the digitalisation of the built environment at the University of Cambridge, and he is a Visiting Professor in the Department of Civil and Environmental Engineering at Imperial College London. As a Mott MacDonald Fellow, Mark provides advice to key clients on digitalisation and broader industry transformation. Previously, Mark was the CTO of Mott MacDonald and the Director of the Centre for Digital Built Britain, where he was the Head of the National Digital Twin programme. Mark is a member of the Prime Minister's Council for Science and Technology.
Abstract This talk explores the importance of ontology in built and natural systems.  Starting with a big-picture overview of 'things that exist and the connection between them', Mark will describe the crucial relationship between interventions, systems and outcomes.  Then, digging deeper, he will relate this to the value of federating digital twins and the need for Data Sharing Infrastructure, which will culminate in making the case for semantic interoperability as an essential enabler.  Mark’s talk will provide insights on how ontology in its various guises can help us to make better decisions and drive better outcomes for people and nature.

We will culminate the talk in a short Q&A session as well as some visions for the future of the SIG from our organisers and community.
