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: Hubble Space Telescope computer | Statement: [Hubble Space Telescope Servicing Mission 3A, replacedComponent, Hubble Space Telescope computer]

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

Target entity: Hubble Space Telescope computer
Context triple: [Hubble Space Telescope Servicing Mission 3A, replacedComponent, Hubble Space Telescope computer]

A. Hubble Space Telescope Power Control Unit
The Hubble Space Telescope Power Control Unit is a critical subsystem that distributes and regulates electrical power for all of Hubble’s instruments and systems, ensuring stable and reliable operation in orbit.
B. Hubble Space Telescope
The Hubble Space Telescope is a large, space-based observatory that has provided some of the most detailed images and data about the universe, revolutionizing modern astronomy and cosmology.
C. Hubble Space Telescope Fine Guidance Sensors
The Hubble Space Telescope Fine Guidance Sensors are high-precision optical instruments that both keep Hubble accurately pointed at astronomical targets and serve as scientific tools for measuring stellar positions and distances.
D. Hubble Space Telescope Orbital Systems Test Platform (HOST)
The Hubble Space Telescope Orbital Systems Test Platform (HOST) was an experimental payload used to test and validate new instruments and technologies for the Hubble Space Telescope in orbit.
E. Hubble Space Telescope science instruments
Hubble Space Telescope science instruments are the suite of specialized cameras, spectrographs, and sensors that capture and analyze astronomical data across multiple wavelengths for the observatory.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
