Infrastructure Research Ontologies is a consortium of champions from UCL, Cranfield, Newcastle, Leeds and Oxford universities.  Led by Professor Liz Varga, UCL, this Champion group addressesed the absence of a high-level infrastructure research ontology (IRO) which will support the identification of gaps and priority areas and will provide a shared framing for stakeholder engagement with DAFNI.

The work involved  7 work packages.  Here is a high-level adressed introduction to the scope:

Management of research ontology​ – Professor Liz Varga, UCL

Different types of infrastructure research ontology​ – Lauren McMillan , UCL

Ontologies and datasets​ – Professor Stephen Hallett and Ian Truckell, Cranfield University

Industrial ontologies – Dr Andrey Postnikov, UCL

Ontologies and scale​ – Tom Russell, University of Oxford

Ontology of ontologies and methods – Dr Luke Smith, Newcastle University

Ontologies for data visualization – Dr Nik Lomax, University of Leeds

Digital Twins and Data Ontologies Event

Date: 2 December 2020
Time: 09:30 – 12:30 GMT
Location: Virtual Event

Digital Twins enabling sustainable development in infrastructure and the built environment and the role of ontologies

Digitalisation and the tools available in the era of Industry 4.0 are enabling many organisations to develop perspectives and strategies on Digital Twins which will bring us closer to understanding how to develop, operate and adapt infrastructure and the built environment. This is essential to provide near real-time agility and responsiveness to prevent things going wrong, and to respond to changes in demand, but also to plan for sustainable development more effectively than ever before.

This will lead to better outcomes for people, business and the environment through better insight of the trade-offs across our infrastructure and city interventions.

Before we rush into Digital Twins we need to get on the same page, or at least find some way of sharing how we each understand our bit of knowledge of the smart city. This means we need to share our ontologies which may not yet have been explicitly stated, and we need to figure out the basis of our ontologies – what assumptions we make, what we can and can’t discover, and what we want to achieve.

Ontologies are essential for us to be able to connect Digital Twins created for different reasons and with different assumptions: for example, route planning and smart motorways.

This event shared exciting work on Digital Twins and ontologies as well as enabling facilities and ways of thinking. The event counted with the participation of ARUP, Costain, CDBB, UCL and DAFNI.

There was the opportunity to ask speakers about their talks, and join one of three workshops (transport, energy, water) where discussions were led by an industry expert and participants had their say by adding their own virtual post-it notes to an on-line collaborative whiteboard.

Poll Report 

During the event we asked those present three key questions:

  1. What approach do we need to take towards trialling possible solutions?
  2. What capabilities are needed most to make progress on an ecosystem of digital twins?
  3. What governance models should operate for an ecosystem of digital twins?

These are the graphs with the results:
