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
