Coffee cans are generally filled by hand
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'Coffee cans are generally filled by hand; that is, the can is placed under the spout of an automatic filling and weighing machine by an operator who slips on the cover when the can is properly filled.' The passage explicitly confirms that coffee cans are filled by hand with operator involvement.
- qualifier_fidelity 0.70 pass — The claim's qualifiers are mostly faithful to the passage. Viewpoint, stance, sentiment, and time are all appropriate - the author asserts this neutrally without attribution to a named source, and no temporal scope is specified. Context is correctly empty. The quote is verbatim and supports the claim. However, the claim's object designation ('object': 'operator') is somewhat misleading. While the passage does mention an operator in the process, the predicate 'is filled by hand' describes the method (manual filling via an operator), not a direct relationship to the operator as the object would typically suggest in knowledge graph terms. The claim would be more precisely structured with 'method' or similar rather than 'object', though this is a structural rather than qualifier fidelity issue. All five qualifier categories (viewpoint, stance, sentiment, time, context) are faithful to the passage, meeting the 0.7 threshold.
