Triple

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).

Phrase: Minkowski metric η_{μν} | Statement: [Kerr–Schild coordinates, containsTerm, Minkowski metric η_{μν}]

Target entity: Minkowski metric η_{μν}
Context triple: [Kerr–Schild coordinates, containsTerm, Minkowski metric η_{μν}]

• A. Minkowski interval
  The Minkowski interval is the spacetime separation between two events in special relativity, remaining invariant under Lorentz and Poincaré transformations.
• B. Minkowski space-time
  Minkowski space-time is a four-dimensional geometric framework that unifies three-dimensional space and time into a single continuum used to describe events and motion in special relativity.
• C. Ricci-Curbastro
  Ricci-Curbastro is the surname of the Italian mathematician Gregorio Ricci-Curbastro, a pioneer of tensor calculus and differential geometry.
• D. Levi-Civita symbol
  The Levi-Civita symbol is an antisymmetric tensor used in mathematics and physics to represent orientations, cross products, and determinants in multiple dimensions.
• 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. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Minkowski metric η_{μν}
Triple: [Kerr–Schild coordinates, containsTerm, Minkowski metric η_{μν}]

The Minkowski metric η_{μν} is the flat spacetime metric of special relativity, describing a four-dimensional spacetime with Lorentzian signature that serves as the background for many formulations of relativistic physics.
