judge verdicts (4)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact sentence states: 'Increase in the force of muscular contractions was demonstrated in 1892 by De Sarlo and Barnardini for caffein,' which matches the subject-predicate-object relationship and temporal information provided in the claim.
- qualifier_fidelity 0.60 fail — The viewpoint qualifier is incorrect. The passage attributes this claim to named sources (De Sarlo and Barnardini, and separately Kraepelin), not to the author. The claim should specify 'De Sarlo and Barnardini' as the viewpoint, not 'author'. Additionally, the quote is accurate and the time (1892) matches the passage, but the viewpoint error is a critical fidelity issue for a knowledge-graph claim that should preserve source attribution.
- groundedness 1.00 pass — The claim is directly stated in the passage. The opening sentence explicitly states that 'Increase in the force of muscular contractions was demonstrated in 1892 by De Sarlo and Barnardini for caffein,' which precisely matches the subject, predicate, object, viewpoint, and date specified in the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly attributes the finding to De Sarlo and Barnardini as named sources. The stance 'asserts' appropriately reflects the passage's framing of 'demonstrated.' The sentiment is neutral, matching the objective tone of the passage. The time qualifier correctly specifies 1892 with valid_from matching the passage's date. The context is appropriately empty as the passage provides no restrictive context. The quote is verbatim from the passage and directly supports the claim.
