July 2023 – Semantic Web research at LiU

July 27, 2023

Semantic Web Group at ESWC 2023

Our group contributed in several ways to ESWC 2023.

Ying Li and Patrick Lambrix presented their research track paper ‘Repairing EL Ontologies Using Weakening and Completing’ and demo paper ‘A System for Repairing EL Ontologies Using Weakening and Completing’. The teaser is available at https://www.youtube.com/watch?v=L7w5OTm9-aQ.

Olaf Hartig, together with Christian Aebeloe, Amr Azzam and Katja Hose, organized the First International Workshop on Data Management for Knowledge Graphs – DMKG 2023. Sijin Cheng and Olaf Hartig presented their paper ‘A Cost Model to Optimize Queries over Heterogeneous Federations of RDF Data Sources’.

The Semantic Web is an extension of the traditional Web towards having machine processable content and interlinked data on the Web, with well-described semantics. Ideally we would be able to view the whole Web as a large set of interconnected databases, which can be queried and browsed by software systems as well as human users. Semantic Web research at LiU includes areas such as ontologies and ontology engineering (ontology design patterns, ontology alignment and completion, ontology and alignment visualisation), graph databases and triple stores, querying the Web of data, RDF stream processing and complex event processing, as well as applications of these technologies in a number of fields, including open data, security, decision support systems, e-health and e-science, etc. The aim of this blog is to report on the activities of our research group, and make results accessible to a wider audience.
