  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly states that Evaristo Conrado Engelberg invented an improved coffee huller in 1885, 'which, three years later, was patented in the United States,' confirming the patent occurred in 1888.
  • qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, sentiment, quote, and context are all correct. The time qualifier is appropriate given the passage's phrasing "three years later" (1885 + 3 = 1888). However, there is a minor issue: the claim uses "valid_from: 1888" which should be null since the passage only provides a relative time reference ("three years later") without explicitly stating 1888 as a specific date for the patent grant itself - the passage only states 1888 as when the company was organized. A strict reading would keep the temporal reference as "three years later" without normalizing to 1888 in valid_from.

  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence, which explicitly says 'In 1885 Evaristo Conrado Engelberg of Piracicaba, Sao Paulo, Brazil, invented an improved coffee huller.' All elements (subject, predicate, object, and time) are precisely supported by the text.
  • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage presents this as factual statement, not attributed to a named source). Stance is correctly marked as 'asserts' - the passage states this as fact. Sentiment is neutral, matching the passage's neutral presentation. Time qualifier correctly shows 1885 as both when and valid_from, with valid_to as null since the passage provides no end date. Context is appropriately empty as the passage does not restrict to a particular sense or role. The quote is verbatim and directly supports the claim.
