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: geodetic reference ellipsoid
Context triple: [GRS80, instanceOf, geodetic reference ellipsoid]
  • A. reference ellipsoid chosen
    A reference ellipsoid is a mathematically defined, smooth, oblate spheroid that approximates the shape of the Earth (or another celestial body) and serves as a standard surface for geodetic calculations and coordinate systems.
  • B. geodetic datum
    A geodetic datum is a reference framework consisting of a defined origin, orientation, and scale used to precisely locate points on the Earth’s surface in terms of latitude, longitude, and elevation.
  • C. geodetic reference point
    A geodetic reference point is a precisely surveyed physical location on the Earth's surface used as a fixed coordinate reference for mapping, surveying, and geospatial measurements.
  • D. geodetic coordinate system
    A geodetic coordinate system is a reference framework that specifies locations on or near the Earth's surface using latitude, longitude, and often height relative to a defined ellipsoidal model of the Earth.
  • E. geodetic standard
    A geodetic standard is an agreed-upon reference framework, model, or set of conventions used to define positions, shapes, and measurements on or near the Earth’s surface consistently and accurately.
  • 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.
