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.

Target class: Lorentzian metric
Context triple: [Kerr metric, instanceOf, Lorentzian metric]
  • A. Lorentzian manifold
    A Lorentzian manifold is a smooth manifold equipped with a metric tensor of signature \((-+\cdots+)\) (or its variants) that models spacetime in general relativity by distinguishing timelike, spacelike, and null directions.
  • B. pseudo-Riemannian manifold chosen
    A pseudo-Riemannian manifold is a smooth manifold equipped with a nondegenerate, symmetric metric tensor of arbitrary signature that allows measurement of lengths and angles, including those with indefinite sign as in spacetime geometry.
  • C. Eddington–Finkelstein coordinate system
    The Eddington–Finkelstein coordinate system is a reformulation of the Schwarzschild spacetime using null (lightlike) coordinates that smoothly extend across the event horizon, eliminating the coordinate singularity present in standard Schwarzschild coordinates.
  • D. flat space-time
    Flat space-time is a conceptual class representing a four-dimensional continuum with zero curvature, where the geometry is described by the Minkowski metric and special relativity holds exactly.
  • E. conformal spacetime diagram
    A conformal spacetime diagram is a rescaled representation of spacetime in which light rays always travel at 45 degrees, preserving causal structure while compactifying infinite regions into a finite, manageable picture.
  • 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.
