Workshop on Graph-enhanced LLMs for trustwOrthy Web data management

Held as part of The ACM Web Conference (WWW ’26)

April 13-14, 2026
Dubai, United Arab Emirates

About the workshop

The recent growth of 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. Exploring the synergies between LLMs and graphs is critical to building data-driven applications where correctness and accountability are necessary.

Topics

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

  • Graph-based retrieval and reasoning for verifiable LLM responses.
  • Detection and mitigation of hallucinations, bias, and misinformation in LLMs using graph-based techniques.
  • Graph databases and LLMs for explainability, accountability, and provenance in data management.
  • 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.
  • Graph-based prompting and retrieval-augmented generation (RAG) strategies for reliability and robustness.
  • Evaluation benchmarks and metrics for reliability and trustworthiness in graph-enhanced LLMs.
  • Applications of graph-enhanced LLMs in domains such as Web data management, scientific knowledge, and enterprise data.
  • Agentic AI for structured reasoning and decision-making over graph-based knowledge.
All submission deadlines are end-of-day in Anywhere on Earth (AoE) time zone.
