This volume presents the proceedings of the 3rd International Workshop
on Semantics and the Web for Transport 5 (Sem4Tra) held online, September
6, 2021, co-located with SEMANTiCS 2021 (September 6-9, Amsterdam & On-
line). Sem4Tra is focused on the application of semantic technologies over the
transport domain and its heterogeneous data, with a particular focus on how
these technologies could facilitate the Mobility-as-a-Service (MaaS) paradigm.
The third edition of the workshop also called for contributions in the context of
Smart Cities.
Smart Cities could not be realized without envisioning a change towards the
MaaS paradigm for integrated and intelligent transportation. MaaS improves
every aspect of transportation from ticketing to navigation, from traffic to park-
ing management, and from car/bike sharing to door-to-door travel. However,
to make MaaS a reality, challenges in data integration must be addressed. The
development of multimodal travel information, planning and booking services,
and the interoperability between business applications are currently limited due
to the fragmentation and incompatibility of interchange formats and protocols
both within and across transport sectors.
The technology known as RDF, Linked Data and the Semantic Web, pro-
poses a framework to discuss the semantics of terms in a decentralized fashion on
web-scale. As MaaS is decentralized by definition, the Sem4Tra workshop targets
researchers and practitioners that are contributing to transform the transporta-
tion sector by proposing new semantic-based solutions to achieve the MaaS ob-
jectives. Moreover, Sem4Tra is an opportunity for disseminating and discussing
use cases and studies showing the application of semantic technologies in the
Transport domain to tackle the above-mentioned challenges.
The articles included in this volume went through a peer-review process
where each submission was reviewed by at least two reviewers. The reviews were
open and public, and hosted at Open Review6 . We accepted six papers (four
long research/experience papers, one short research paper, and a system/demo
paper) and a journal paper presentation. The articles tackle open problems and

• Semantic Conversion of Transport Data Adopting Declarative Mappings:
an Evaluation of Performance and Scalability. Mario Scrocca, Alessio
Carenini, Marco Comerio, Irene Celino.
• On the Visualization of Semantic-based Mappings. Nicolò Oreste Pin-
ciroli Vago, Mario Sacaj, Mersedeh Sadeghi, Safia Kalwar, Andrea vo-
gelsang, Matteo G. Rossi.
• Enabling Cross-Border Travel Offers Through National Access Point Fed-
eration via Metadata Harmonisation. Alessio Carenini, Andrea Fiano,

The workshop program included a keynote from Kasia Bourée, expert within
the European project Data4PT7 , entitled Transmodel in RDF? and dealing with
challenges and opportunities of an ontological representation of Transmodel8 , the
European reference data model for public transport information.
