Tripartite-GraphRAG via Plugin Ontologies

16 September 2025 · FGWM workshop at KI 2025, Potsdam (GI Special Interest Group on Knowledge Management)

Documents, concepts and cases in one graph, so a language model answers from a consistent chain of evidence instead of loose text chunks.

The research

Language models answer well only when the right evidence reaches the prompt. We connect text segments, domain concepts and cases in one tripartite graph and assemble the prompt along explainable paths.

What it changes in practice

Answers with sources, in the customer's own documents. The same mechanism carries the decision document: every figure traces back to a process step.
