Graph search can be syntactically right and still mean the wrong thing
A can fail even when the retriever, the , and the query syntax all look correct. The real problem can be semantic: the system follows valid relationships but combines them into a false conclusion. For example, “Person manages Team” and “Team uses Tool” can both be true, but that does not mean the person personally uses the tool.
A query engine usually checks whether a query is valid, not whether the combined meaning is valid. caught type mismatches, but it did not check whether a person should inherit a team’s tool use through a management relationship. Query logging showed which retrieval steps ran, but not why the final answer was wrong.
Asking the to check itself did not help, because the supported the wrong conclusion and made the model confirm the mistake.
Key points
- Valid graph edges can still produce a false combined conclusion.
- A query engine checks syntax, not real-world meaning.
- can miss whether one entity should inherit another entity’s property.
- Query logging shows what ran, but not why the answer was wrong.
- A self-check can fail when the already points to the wrong answer.
