GraphEval Flags 1 of 3 LLM Claims Using Knowledge Graphs and NLI

Summary
A simulated GraphEval run marked 1 of 3 extracted triples as a hallucination, isolating a false claim that the framework needs an expensive enterprise server farm.
The method first converts an LLM answer into subject-relationship-object triples, then checks each claim against source context with an NLI model; anything not labeled entailment is flagged.
In the example, two triples about GraphEval being an evaluation framework and using knowledge graphs were grounded, while the server-farm claim was rated neutral and treated as hallucinated.
Amazon researchers proposed GraphEval as an explainable alternative to single-score evaluation, aiming to show exactly where hallucinations appear in model outputs.
