How this triple was built (1 step)

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.

CD Concept disambiguation gpt-5-mini-2025-08-07
Target class: Pleistocene stratigraphic unit
Context triple: [Illinoian Stage, instanceOf, Pleistocene stratigraphic unit]
  • A. stratigraphic unit chosen
    A stratigraphic unit is a volume of rock or sediment defined and distinguished from adjacent material by its recognizable and mappable physical, chemical, or paleontological characteristics and its position in the geological record.
  • B. Pleistocene glaciation
    Pleistocene glaciation refers to the series of extensive, repeated ice ages during the Pleistocene epoch when large ice sheets advanced and retreated over vast areas of the Northern Hemisphere, profoundly shaping Earth’s landscapes and climate.
  • C. Paleocene formation
    A Paleocene formation is a geologic rock unit composed of sediments or volcanic materials deposited during the Paleocene epoch (about 66–56 million years ago), preserving evidence of early Cenozoic environments and life.
  • D. Mississippian-age geologic formation
    A Mississippian-age geologic formation is a body of rock deposited during the Mississippian subperiod of the Carboniferous, characterized by its distinct lithology, fossil content, and stratigraphic position that record marine and terrestrial environments of that time.
  • E. geologic time interval
    A geologic time interval is a span of Earth’s history defined by characteristic rock layers, fossil assemblages, and major geological or biological events, used to organize and correlate geological and paleontological data.
  • F. None of above.

Provenance (1 batch)

The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
