2nd Workshop on Graph-enhanced LLMs for trustwOrthy Web data management

Held as part of The International Semantic Web Conference (ISWC ’26)

October 25-29, 2026
Bari, Italy

About the workshop

The recent growth of Large Language Models (LLMs) has expanded possibilities in data management, enabling powerful natural language access, reasoning, and decision support. However, reliability and trustworthiness remain major challenges when deploying LLMs in sensitive domains. Graph-based representations of knowledge and data (e.g., knowledge graphs and property graphs) provide a promising avenue to address these challenges.

LLMs generate fluent responses but often struggle with factuality, bias, hallucinations, and a lack of explainability. Graphs, on the other hand, provide structured, interconnected representations that can serve as grounding and validation layers for LLM-based systems. In this context, Semantic Web technologies offer standardized graph-based frameworks (e.g., RDF and ontologies) to formally model, link, and reason over knowledge.

Submission
Guidelines

Formatting Requirements. We invite research, industry, application contributions, and software demonstration submissions. Regular papers presenting original work are solicited. Moreover, discussion papers containing descriptions of results already published are also welcomed. There are three submission formats:

  • Regular papers (up to 12 pages + references). Original research works. Regular papers must be original and not simultaneously submitted to another journal or conference.

  • Discussion papers (up to 8 pages + references). Results and ideas of interest to the workshop audience, including extended abstracts of recent authors’ publications, papers currently under submission, position papers, system and application descriptions, and presentations of preliminary results.

Paper selection will be based on originality, clarity, and technical quality. Submissions of papers must be in English, in PDF format, and formatted following the new CEUR-ART 1-column style, which is the style requested for the camera-ready preparation (Overleaf template). Accepted papers will be included in the proceedings. Proceedings will be published on CEUR-WS.org and indexed in Scopus. After acceptance, authors are required to re-submit the final PDF.

For enquiries, please email us at: glowiswc26@easychair.org.

Topics

We invite submissions that address, but are not limited to, the following themes:

  • Detection and mitigation of hallucinations, bias, and misinformation in LLMs using graph-based techniques.
  • Property graphs as a foundation for profiling, reliability, and LLM-grounded reasoning.
  • Querying property graphs with natural language interfaces powered by LLMs.
  • LLMs as assistants for constructing and validating reliable knowledge graphs.
  • Agentic AI for structured reasoning and decision-making over graph-based knowledge.
  • Semantic Web standards for grounding and verifying LLM-generated outputs.
  • Ontology-based reasoning and neuro-symbolic approaches for trustworthy LLM-driven systems.
  • Integration of Knowledge Graphs for retrieval-augmented generation and fact-checking.
  • Applications of LLMs combined with Semantic Web technologies for reliable Web-scale data management, scientific knowledge representation, and enterprise knowledge graphs.
  • Evaluation benchmarks and metrics for reliability and trustworthiness in graph-enhanced LLMs.
All submission deadlines are end-of-day in Anywhere on Earth (AoE) time zone.
