The Semantic Web group contributed to the 18th International Semantic Web Conference – ISWC 2023 in several ways.

Olaf Hartig is co-author of the paper “FedShop: A Benchmark for Testing the Scalability of SPARQL Federation Engines” presented in the resource track.

Huanyu Li, Olaf Hartig and Patrick Lambrix, together with Rickard Armiento presented a demonstration of the system “OBG-gen: Ontology-Based GraphQL Server Generation for Data Integration”.

Patrick Lambrix and Huanyu Li, together with Bo Fu, Susana Nunes and Catia Pesquita organized the  8th International Workshop on Visualization and Interaction for Ontologies, Linked Data and Knowledge Graphs – VOILA 2023. Proceedings are available at CEUR.

Huanyu Li co-organized the Ontology Alignment Evaluation Initiative 2023. Mina Abd Nikooie Pour, Ying Li, Huanyu Li and Patrick Lambrix co-organized two tracks in the Ontology Alignment Evaluation Initiative (the Anatomy track and the Interactive track).

Eva Blomqvist together with Raghava Mutharaju, Agnieszka Ławrynowicz, Pramit Bhattacharyya, Luigi Asprino, and Gunjan Singh organized the 14th Workshop on Ontology Design and Patterns – WOP 2023. At WOP, Eva Blomqvist presented the paper “Cross-domain Modelling – A Network of Core Ontologies for the Circular Economy” by Eva Blomqvist, Huanyu Li, Robin Keskisärkkä, Mikael Lindecrantz, Mina Abd Nikooie Pour, Ying Li and Patrick Lambrix.

Olaf Hartig was invited speaker at QuWeDa 2023, the 7th Workshop on Storing, Querying and Benchmarking Knowledge Graphs. His talk was titled “GraphQL and RDF: Quo Vadis?”

At the 18th International Workshop on Ontology Matching, Patrick Lambrix presented the paper “Repairing Ontology Networks using Weakening and Completion” by Ying Li and Patrick Lambrix. Huanyu Li presented results of the Ontology Alignment Evaluation Initiative. Further, Huanyu Li was co-author of the paper “A simple standard for ontological mappings 2023: updates of data model and outlook”.

Mikael Lindecrantz presented part of his thesis work “Decentralized Digital Twins of Circular Value Networks” at the Doctoral Consortium.

Eva Blomqvist was Research Track PC co-chair for ISWC 2021 and Olaf Hartig was a senior PC member.

Ying Li and Patrick Lambrix presented the poster ‘An Approach for Repairing Incoherent Ontologies Repairing’. The teaser video for this paper was selected as best teaser video. The paper is available at http://ceur-ws.org/Vol-2980/paper372.pdf and the teaser video at https://www.youtube.com/watch?v=QQCWGBFhhRw.

Patrick Lambrix, Huanyu Li, Mina Abd Nikooie Pour and Ying Li co-organized two tracks in the Ontology Alignment Evaluation Initiative (the Anatomy track and the Interactive track).

Patrick Lambrix, together with Catia Pesquita and Vitalis Wiens organized VOILA 2021 – the 6th International Workshop on Visualization and Interaction for Ontologies and Linked Data. At VOILA 2021, Mina Abd Nikooie Pour, Huanyu Li and Patrick Lambrix, together with Rickard Armiento presented the paper ‘A First Step towards a Tool for Extending Ontologies’. Ying Li and Patrick Lambrix, together with former member of the group Zlatan Dragisic presented ‘RepOSE-CTab – A Protégé Plugin for Completing Ontologies’.

Successful workshop on Ontologies for Materials-Databases Operability

Patrick Lambrix, together with Rickard Armiento, Welzel Andersen, Gareth Conduit, Luca Ghiringhelli, and Cormac Toher, and advised by Saulius Gražulis, Giovanni Pizzi, Gian-Marco Rignanese and Markus Scheidgen, organized OMDI 2021 – Workshop on Ontologies for Materials-Databases Interoperability on October 5-7, 2021 as a hybrid workshop with Linköping University as host.

The workshop had sessions on Ontologies and their place in open science, Ontologies for data exchange, Ontologies in materials science, Ontologies for materials properties, Ontologies for data integration, and Ontology use in applications. Each session had several invited speakers and ample time for discussion. There was also a poster session.

From our group there were presentations by Patrick Lambrix on debugging and completing ontologies and Huanyu Li about the Materials Design Ontology developed by our group.

Recordings of the sessions will be made available via the workshop home page.
