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).

Input

Phrase: Earth Orientation Parameters | Statement: [International Earth Rotation and Reference Systems Service, provides, Earth Orientation Parameters]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Earth Orientation Parameters
Context triple: [International Earth Rotation and Reference Systems Service, provides, Earth Orientation Parameters]

A. International Earth Rotation and Reference Systems Service
The International Earth Rotation and Reference Systems Service (IERS) is an international organization that monitors Earth's rotation and maintains global reference systems used for precise timekeeping, navigation, and geodesy.
B. Earth rotation
Earth rotation is the spinning of our planet on its axis, which produces the cycle of day and night and underlies the measurement of time.
C. Earth gravity model
The Earth gravity model is a mathematical representation of Earth's gravitational field used for precise positioning, navigation, and geodetic calculations.
D. Keplerian orbital elements
Keplerian orbital elements are a set of parameters that uniquely describe the size, shape, and orientation of an orbit and the position of an orbiting body along that path.
E. Gauss’s planetary equations
Gauss’s planetary equations are a set of differential equations in celestial mechanics that describe how a planet’s orbital elements change over time under the influence of perturbing forces.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
