Every LLM step that produced this triple, in pipeline order — named-entity classification, the disambiguation choices (the exact options shown, with the pick highlighted), and the generated description. The batch + timestamp of each is in the Provenance table below.

NER Named-entity recognition gpt-5-mini
Instruction
Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).
Input
Phrase: Late Devonian extinction | Statement: [Paleozoic Era, majorEvent, Late Devonian extinction]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Late Devonian extinction
Context triple: [Paleozoic Era, majorEvent, Late Devonian extinction]
  • A. Permian–Triassic mass extinction
    The Permian–Triassic mass extinction was the most severe biodiversity crisis in Earth's history, wiping out the majority of marine and terrestrial species around 252 million years ago and marking the boundary between the Paleozoic and Mesozoic eras.
  • B. Early Devonian
    The Early Devonian was the initial subdivision of the Devonian Period, marked by the diversification of early fishes and the spread of primitive vascular land plants across emerging terrestrial ecosystems.
  • C. Cambrian explosion
    The Cambrian explosion was a relatively brief period around 541 million years ago when most major animal groups rapidly appeared in the fossil record, dramatically increasing the complexity and diversity of life on Earth.
  • D. Cretaceous–Paleogene boundary
    The Cretaceous–Paleogene boundary marks the geological transition 66 million years ago associated with a mass extinction event that wiped out non-avian dinosaurs and many other species, likely triggered by a large asteroid impact.
  • E. Silurian
    The Silurian is a geologic period of the Paleozoic Era, roughly 443 to 419 million years ago, marked by the stabilization of Earth’s climate, widespread shallow seas, and significant diversification of early marine life and the first land plants.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
