NER
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).

gpt-5-mini-2025-08-07
Target entity: Painlevé–Gullstrand time Context triple: [Painlevé–Gullstrand coordinates, hasTimeCoordinate, Painlevé–Gullstrand time]
-
A.
Painlevé–Gullstrand coordinates
chosen
Painlevé–Gullstrand coordinates are a coordinate system for the Schwarzschild black hole that is regular at the event horizon and represents spacetime as seen by freely falling observers.
-
B.
Eddington–Finkelstein coordinates
Eddington–Finkelstein coordinates are a coordinate system in general relativity that smoothly covers a black hole’s event horizon, avoiding the coordinate singularity present in standard Schwarzschild coordinates.
-
C.
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.
-
D.
Kruskal–Szekeres coordinates
Kruskal–Szekeres coordinates are a maximal extension coordinate system used in general relativity to smoothly describe the entire spacetime of a Schwarzschild black hole, including regions across the event horizon.
-
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.
PD
Predicate disambiguation

Target predicate: hasTimeCoordinate Context triple: [Painlevé–Gullstrand coordinates, hasTimeCoordinate, Painlevé–Gullstrand time]
-
A.
timeCoordinateType
Indicates the specific temporal reference system or framework used to define and interpret time coordinates for an event or entity.
-
B.
hasTemporalLocation
Indicates that something occurs, exists, or is valid during a specific time or time interval.
-
C.
hasTimeDepth
Indicates that something possesses or spans a measurable extent of time, such as duration, historical depth, or temporal layering.
-
D.
hasCoordinates
Indicates that an entity is associated with specific spatial coordinates that define its position in a given reference system.
-
E.
hasCoordinatesType
chosen
Indicates that an entity is associated with a specific type or system of coordinates used to define its position.
- F. None of above.
