HANBURY, DANIEL
On the use of coffee leaves in Sumatra
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage as a bibliographic reference: 'HANBURY, DANIEL. On the use of coffee leaves in Sumatra. Pharmaceutical Journal, 1853, XIII: 207-209.' The subject, predicate, and object match exactly with the title of the referenced article.
- qualifier_fidelity 0.65 fail — VIEWPOINT: The claim attributes the statement to 'author' but the passage explicitly names 'HANBURY, DANIEL' as the source. The viewpoint must be 'HANBURY, DANIEL' not 'author'. TIME: The claim sets valid_from to '1853' (the publication year) but the passage provides no information about when coffee leaves were actually used in Sumatra—only when the article was published. The time qualifier should be null to avoid conflating publication date with the temporal scope of the claim itself.
- groundedness 1.00 pass — The claim is directly stated in the passage. HANBURY, DANIEL's publication title explicitly reads 'On the use of coffee leaves in Sumatra,' which directly supports the subject-predicate-object relationship without any rewording or inference required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly identifies HANBURY, DANIEL as the source (from the bibliographic entry). The stance 'asserts' is appropriate as the passage presents this as a factual topic of discussion. The sentiment is neutral, matching the objective tone of the title. The time qualifiers are correctly null since the passage provides no temporal information about when coffee leaves were used. The context is empty as the passage provides no restrictive context beyond the geographic location. The quote 'On the use of coffee leaves in Sumatra' appears verbatim in the passage and directly supports the claim.
