Named-entity recognition

Before disambiguation, gpt-5-mini classified whether the object phrase is a named entity — the step behind the object's NE type shown above.

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: Mu2e experiment | Statement: [Fermilab Booster, supportsExperiment, Mu2e experiment]

Context triple: [Fermilab Booster, supportsExperiment, Mu2e experiment]
  • A. MINOS experiment
    The MINOS experiment is a long-baseline neutrino oscillation project that studied how neutrinos change type as they travel from Fermilab to a distant underground detector.
  • B. Muon g-2 experiment
    The Muon g-2 experiment is a high-precision particle physics experiment that measures the anomalous magnetic moment of the muon to test the limits of the Standard Model and search for signs of new physics.
  • C. MINERvA
    MINERvA is a high-precision neutrino scattering experiment at Fermilab designed to study neutrino interactions with various nuclear targets to improve understanding of neutrino-nucleus physics.
  • D. DUNE experiment
    The DUNE experiment is a major international neutrino physics project designed to study neutrino oscillations, matter–antimatter asymmetry, and proton decay using intense neutrino beams and massive underground detectors.
  • E. NOvA experiment
    The NOvA experiment is a long-baseline neutrino oscillation project that studies how neutrinos change type as they travel from Fermilab to a distant detector in northern Minnesota.
  • F. None of above. chosen

How the object was described

The object's one-sentence description was generated by prompting gpt-5.1 with the object name and this triple as context.

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]"
Input
Entity: Mu2e experiment
Triple: [Fermilab Booster, supportsExperiment, Mu2e experiment]
Generated description
The Mu2e experiment is a high-energy physics project at Fermilab designed to search for the extremely rare conversion of muons into electrons without neutrinos, probing physics beyond the Standard Model.
