Preface




The concept of digital twins, as virtual replicas of physical entities, has gained sig-
nificant 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 International Workshop on Semantic Digital Twins (SeDiT) was established
to facilitate the progress of this emerging technology. Its aims are twofold. Firstly,
to drive the discussion about current trends and future challenges of semantic dig-
ital 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.
    In this third edition of the workshop we received 6 submissions which un-
derwent thorough reviewing by three reviewers each. Based on these reviews,
we accepted 5 papers for presentation. We thank all authors and PC members for
making the workshop a success.
    We hope that SeDiT will be a fruitful meeting that will stimulate further devel-
opments in the field.
