Scenario definition · S2

Answer is not available in the knowledge base

The requested information is absent from the source set.

What this scenario means

This scenario checks whether the system recognises that the source set does not contain the answer and responds without making one up. The correct behaviour is an honest abstention or equivalent acknowledgement of the gap, rather than a fabricated answer.

What we evaluate

  • Whether it indicates that the information cannot be found in the source set.
  • Whether it avoids inventing an answer when the source set is missing the fact.
  • Whether it responds with an honest refusal or equivalent no-answer behaviour.
