Location: The 2nd edition of the ST4DM Workshop will be held in Lisbon (Portugal) on July 18. It will be co-located with several events as part of FLoC 2026, including KR (
https://kr.org/KR2026/), DL (
https://dl-2026.github.io/), ICLP (
https://www.semsys.aau.at/events/iclp2026/) and LICS (

Goal: The Semantic Technologies for Data Management (ST4DM) workshop emerged from the need for a dedicated venue that focuses on applying semantic technologies to data management. Addressing this area requires an integrated perspective that unifies data with its underlying semantics.
Topics of Interest: This workshop solicits contributions that advance the theory, systems, and applications of semantic technologies for data management. Topics of interest include, but are not limited to:
• Knowledge Graphs (KGs) and Virtual Knowledge Graphs (VKGs) / Ontology-Based Data Access (OBDA)
• Ontology-mediated query answering, query rewriting, and complexity/tractability results
• (V)KG construction, refinement, enrichment,and schema/mapping design
• Provenance, explainability, and accountability for (V)KG query answers
• Ontologies, metadata vocabularies, and standards (OWL/RDF/R2RML/SHACL)
• Temporal, spatial, and other non-standard KG modalities
• Performance, scalability, distributed execution, and security for (V)KGs
• Evolution, updates, and preservation of (V)KGs (consistency and incremental reasoning)
• Intersections with machine learning, neural symbolic methods, and LLM-augmented pipelines
• (V)KG analytics, benchmarking, and evaluation methodologies
