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: Common Muon and Proton Apparatus for Structure and Spectroscopy | Statement: [COMPASS, fullName, Common Muon and Proton Apparatus for Structure and Spectroscopy]

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

Target entity: Common Muon and Proton Apparatus for Structure and Spectroscopy
Context triple: [COMPASS, fullName, Common Muon and Proton Apparatus for Structure and Spectroscopy]

A. Antiproton Decelerator
The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
B. Linac4
Linac4 is a linear accelerator at CERN that serves as the first stage of the proton acceleration chain for the Large Hadron Collider and other experiments.
C. LHC Injectors Upgrade (LIU)
The LHC Injectors Upgrade (LIU) is a major CERN project to modernize and enhance the performance of the accelerator chain feeding the Large Hadron Collider, enabling higher beam intensities and luminosities for future physics runs.
D. Proton Synchrotron
The Proton Synchrotron is a historic circular particle accelerator at CERN that has played a key role in high-energy physics research and in feeding beams to larger colliders.
E. LHC injector chain
The LHC injector chain is the sequence of accelerators and beamlines at CERN that progressively boost and prepare particle beams before they are injected into the Large Hadron Collider.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.

NEDg Description generation gpt-5.1

Instruction

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]"
