Call For Papers

3rd International Workshop on Semantics and the Web For Transport
(#Sem4Tra2021) in conjunction with SEMANTiCS2021

Sem4Tra is a half-day workshop on Semantics and the Web For Transport.
It is co-located with the SEMANTiCS conference 2021.

Brief Abstract


Smart Cities could not be realized without envisioning a change towards
the Mobility-as-a-Service (MaaS) paradigm for integrated and intelligent
transportation. MaaS improves every aspect of transportation from
ticketing to navigation, from traffic to parking 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. This workshop seeks to advance MaaS through Semantic Web,
Linked Data and Knowledge Graph techniques. In-scope are methods to
query and reason over integrated data on the web that can help an
end-user to plan and book a trip from A to B.

We target researchers and practitioners who are contributing to the
transformation of the transportation sector by proposing new solutions
based on semantic techniques and technologies to realize MaaS
objectives. The workshop is an opportunity for disseminating and
discussing use cases and studies showing the application of semantic and
web technologies in the transport domain to tackle the aforementioned

Topics of interest


1) Decentralized data management

* Query languages and methods for a Web of Transport Data

* Creating automated alignments between datasets using the various

* Recommendations for mobility specification builders to raise
interoperability between specifications

* Alignments with existing or upcoming general-purpose Web API
specifications such as W3C Web payments or Solid

* Interfaces between enterprise data and the Semantic Web

2) The exploitation of Transport Data on the Web

* Challenges and opportunities for route planning and ticketing

* Personalized route planning taking into account data stored on your
client or personal data space

* Anonymization in the mobility space for data sharing

3) Benchmarking of Web Infrastructure

* Comparing ticketing API architectures

* Comparing route planning API architectures

* Publishing and querying planned transport data and their live
updates on the Web

4) Knowledge Graphs and Ontologies in the transportation domain

* Aligning regional vocabularies with international reference domain
models such as Transmodel, NeTEx, SIRI or DATEXII

* Reusing existing linked datasets, such as Geonames, OpenStreetMap or
Wikidata, for MaaS use cases

* Bridging the gap with non-RDF specifications such as
MobilityDataSpecification, General Transit Feed Specification,
General Bike Feed Specification, TOMP API or MaaS API

* Building a Knowledge Graph of the transportation domain by
integration and conversion of heterogeneous data sources (e.g.,
National Access Points or local sources)

5) Semantic technology applications and datasets on smart mobility
