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).

Target entity: Lemaître–Tolman–Bondi metric Context triple: [LTB metric, fullName, Lemaître–Tolman–Bondi metric]
-
A.
Lemaître–Tolman metric
chosen
The Lemaître–Tolman metric is an exact spherically symmetric, inhomogeneous solution of Einstein’s field equations used in cosmology to model non-uniform distributions of matter without assuming spatial homogeneity.
-
B.
Gödel metric
The Gödel metric is a solution to Einstein's field equations that describes a rotating universe allowing for closed timelike curves and thus the theoretical possibility of time travel.
-
C.
Kasner solution
The Kasner solution is an exact anisotropic vacuum solution to Einstein's field equations that describes a homogeneous but directionally dependent expanding (or contracting) universe in general relativity.
-
D.
Milne universe model
The Milne universe model is a cosmological model that describes an empty, expanding universe with negative spatial curvature, serving as a special-relativistic alternative to general relativistic cosmologies.
-
E.
Reissner–Nordström metric
The Reissner–Nordström metric is an exact solution in general relativity describing the spacetime geometry outside a static, spherically symmetric, electrically charged black hole.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (2 batches)
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.
