Coffee planting in Ceylon was an important industry for a century, until the so-called Ceylon leaf disease attacked the plantations in 1869
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence: 'Coffee planting in Ceylon was an important industry for a century, until the so-called Ceylon leaf disease attacked the plantations in 1869.' The subject, predicate, object, timeframe, and context all match the passage exactly without requiring outside knowledge or generalization.
- qualifier_fidelity 0.60 fail — The 'time' qualifier is unfaithful. The passage states coffee planting 'was an important industry for a century, until the so-called Ceylon leaf disease attacked the plantations in 1869.' This means the century-long period ENDED in 1869, not that it was valid_to 1869 (which suggests 1869 as the endpoint). The valid_to should be null or the 'when' should be reformulated to clarify the period ended at 1869. Additionally, the 'context' field should be empty or null since the passage provides no restriction to a specific sense or role of coffee planting—it refers to the industry generally. The quote is accurate and viewpoint/stance/sentiment are correct.
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'Coffee planting in Ceylon was an important industry for a century, until the so-called Ceylon leaf disease attacked the plantations in 1869.' The exact quote provided matches the passage verbatim, confirming full groundedness.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is appropriately attributed to the author (the passage itself makes the assertion without citing a named source). The stance is correctly marked as 'asserts' - the passage states this as fact, not disputed. The sentiment is neutral, which matches the factual tone. The time qualifier accurately reflects the passage's temporal scope ('for a century, until...1869' with valid_to set to 1869). The context is appropriately empty as the passage does not restrict coffee planting to a particular sense or role. The quote is verbatim and directly supports the claim.
Further coffee-planting was to be checked by enforcing the law which carried a tax sufficiently high to operate toward restriction
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote provided matches the passage text, which explicitly states that coffee-planting 'was to be checked by enforcing the law which carried a tax sufficiently high to operate toward restriction.'
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (narrator of the passage), the stance is appropriately 'asserts' as the passage states this as a factual plan component, the sentiment is neutral as the passage presents this objectively, the time is correctly null as no specific date is given, the context is appropriately empty, and the quote appears verbatim in the passage supporting the claim about coffee-planting restriction through tax law enforcement.
HILLMAN, JOSEPH. Coffee planting. _New York_, 1902.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly lists 'HILLMAN, JOSEPH. Coffee planting. _New York_, 1902. 16 pp.' This bibliographic entry clearly states that Hillman wrote about coffee planting and published it in 1902.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint 'author' is appropriate as the passage does not attribute the work to a named source but directly presents Hillman as the author. The stance 'asserts' and sentiment 'neutral' match the straightforward bibliographic presentation. The time qualifiers (when: 1902, valid_from: 1902, valid_to: 1902) are correct based on the publication date. The context is appropriately empty as the passage provides no special contextual restriction. The quote appears verbatim in the passage and accurately supports the claim that Hillman wrote about coffee planting.
VAN LEENHOFF, JOHANNES W. Coffee planting in Porto Rico. _Mayaguez_, 1904.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The bibliographic entry explicitly states that Johannes W. Van Leenhoff wrote 'Coffee planting in Porto Rico' and published it in Mayaguez in 1904, matching all details in the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly identifies the author as 'author' (not attributed to a named source making a claim). The stance 'asserts' is appropriate for a bibliographic entry. The sentiment 'neutral' matches the factual nature of the reference. The time qualifiers correctly reflect 1904 as both when and valid dates. The context 'Porto Rico' accurately captures the geographic scope stated in the passage. The quote appears verbatim in the passage and directly supports the claim about Van Leenhoff writing about coffee planting in Porto Rico.
