Seventh International Workshop on Semantics for Transport and Logistics

Co-located with the SEMANTiCS Conference 2026

Ghent - 15th of September 2026

Sem4Tra Call for Papers

Integrated and intelligent transportation requires an interoperable ecosystem in which stakeholders are able to exchange and integrate data flows automatically and in a trusted manner. A Transport Data Space could improve every aspect of the passenger journey, from ticketing to navigation, from traffic to parking management, and from car/bike sharing to door-to-door travel. A Logistics Data Space should safely and securely provide all information for optimizing supply chains in terms of both saving time and reducing carbon emissions.

The federated and heterogeneous nature of the transport and logistics sectors makes the application of Dataspaces and semantic technologies especially relevant. The development of multimodal travel information, planning, and booking services, as well as interoperability between business applications, is currently limited due to the fragmentation and incompatibility of interchange formats and protocols both within and across transport sectors. Technologies from the field of semantic interoperability can provide various kinds of solutions:

  • Dataspace technology enables participants to regulate in a detailed way, which participants can access parts of the data and under what conditions.
  • Semantic technologies can provide ways to align differing meanings among logistic modalities.
  • A Digital Product Passport/Provenance can gather all information from heterogeneous sources to give a full picture of a product's heritage throughout its lifecycle.

This workshop seeks to advance the Transport and Logistics Data Space 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 plan and book a trip from A to B, as well as extract insights and share information for supply chain operations management. We target researchers and practitioners who are contributing to the transformation of passenger and freight transportation by proposing new solutions based on semantic techniques and technologies, as well as practitioners, policy makers, and standardisation experts. The workshop is an opportunity to disseminate and discuss use cases and studies demonstrating the application of semantic and web technologies to tackle the aforementioned challenges.

Topics

  • Transport & Logistics Data Spaces
  • Query languages and methods for a Web of Transport Data
  • Creating automated alignments between datasets using the various specifications
  • 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 Linked Web Storage
  • Interfaces between enterprise data and the Semantic Web
  • Discovery methods for mobility information through for example DCAT-based portals
  • Semantic Interoperability & Integration
  • Aligning transport and logistics specifications
  • Bridging the gap with non-RDF specifications such as MobilityDataSpecification, General Transit Feed Specification, General Bike Feed Specification, TOMP API or MaaS API
  • Bridging non-RDF and semantic representations
  • Integration pipelines and transformation approaches
  • Knowledge Graphs & Semantic Assets
  • Ontology alignments and reuse of open data (Transmodel, Geonames, OSM, Wikidata)
  • Building a Knowledge Graph of the transportation domain by integration and conversion of heterogeneous data sources (e.g., National Access Points or local sources)
  • Extensions, implementations, or algorithms on top of Mobility DCAT-AP
  • Applications, Deployment & Impact
  • Smart mobility, infrastructure, navigation, or booking/ticketing.
  • Making route suggestions and driving planning recommendations more explainable and transparent
  • Applications of Digital Product Passport/Provenance for supply chain tracking or CO2 emissions calculations
  • Lessons learned from deployments and case studies
