Call for Papers

The concept of digital twins, as virtual replicas of physical entities, has gained significant traction in recent years in a range of domains such as industry, construction, energy, health or transport. Digital Twins can be used to view the status of the twinned physical object, without the need to interrogate the object itself. The digital twin can be queried by other software without the need to query the device itself thus relieving pressure on devices, which typically have very limited computational capabilities. Digital twins can also be used for monitoring and diagnostics to optimize device performance without impacting on the physical device.

Digital twins require unambiguous descriptions of both the entity and its digital counterpart, as well as the ability to integrate data from heterogeneous sources of information (including real-time data) and to interact with the physical world. Given these requirements, semantic technologies can play a significant role in the real-world deployment of digital twin technology.

The aims of the SeDIT workshop are twofold. Firstly, to drive the discussion about current trends and future challenges of semantic digital twins. Secondly, to support communication and collaboration with the goal of aligning the various efforts within the community and accelerating innovation in the associated fields.

  • Self-awareness of semantic digital twins
  • Semantic digital twin ecosystems
  • Security and trust for semantic digital twins
  • Privacy and ethics for semantic digital twins
  • Semantic digital twins in industry
  • Semantic digital twins in construction
  • Semantic digital twins in health
  • Semantic digital twins in transport
  • Semantic digital twins in the energy sector

Author Guidelines


Submissions must be in PDF, formatted in the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS). For details on the LNCS style, see Springer’s Author Instructions.


  • Full research papers (8-12 pages)
  • In Use and Experience papers (8-12 pages)
  • Position papers (6-8 pages)
  • Short research papers (4-6 pages)
  • System/demo/in practice papers (4-6 pages)

Review and Publication

All papers and abstracts have to be submitted electronically via OpenReview. We will follow an open reviewing process where:

  • Submissions will be publicly visible after the full submission deadline
  • Review texts will be publicly visible at the end of the reviewing process
  • All members of the community are invited to contribute public reviews and comments to submissions and reviews
Submissions and public annotations are non-anonymous throughout the entire process. Solicited reviewers are initially anonymous, but can optionally choose to disclose their identity after notification. Authors can opt to have rejected contributions removed from OpenReview after a certain period of time.

The accepted contributions will be published in the proceedings of the workshop.

At least one author of each accepted paper has to register for the main conference and each accepted paper needs to be presented by one of the authors at the workshop.


The workshop proceedings are available online as the Volume 2887 of CEUR Workshop Proceedings.



The invited keynote speaker for this edition of the SeDiT workshop is Jakob Beetz, Chair of Computational Design in the Department of Architecture at the RWTH Aachen University.
