Hehner
An analysis of coffee leaves
judge verdicts (4)
- groundedness 0.70 pass — The claim is supported by the passage. HEHNER, O.'s 1879 publication titled 'An analysis of coffee leaves' in the Analyst directly states that coffee leaves were analyzed. The claim's predicate and object are minor rewording of the actual title, making it a valid representation of the passage content.
- qualifier_fidelity 0.60 fail — VIEWPOINT is unfaithful: the passage attributes the statement to 'HEHNER, O.' (a named source), so the claim must use 'Hehner' as viewpoint, not 'author'. CONTEXT is unfaithful: the claim omits that this is specifically about 'coffee leaves' (a distinct sense from coffee beans/seeds), which should be reflected in the context field rather than left empty. The time qualifiers (when/valid_from/valid_to all 1879) are faithful to the publication year. The quote 'An analysis of coffee leaves' appears verbatim and supports the claim.
- groundedness 0.70 pass — The claim is supported by the passage. The bibliographic entry 'HEHNER, O. An analysis of coffee leaves. Analyst, 1879, IV: 84' directly states that Hehner conducted an analysis of coffee leaves in 1879, confirming the subject, predicate, object, viewpoint, and time with minor rewording from the original title.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The viewpoint (Hehner), stance (asserts), sentiment (neutral), and time (1879) all align correctly with the HEHNER, O. entry: 'An analysis of coffee leaves. Analyst, 1879, IV: 84.' The quote is verbatim and accurate. The only minor issue is the context qualifier 'botanical analysis' - while the passage indicates this is an analytical/chemical study of coffee leaves (published in the Analyst journal), the passage does not explicitly specify the context as 'botanical analysis.' The context appears to be chemical/compositional analysis rather than strictly botanical. However, since the context is not contradicted by the passage and represents a reasonable interpretation of the work, this is a minor deviation. All other qualifiers are faithful.
