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: CLAS detector | Statement: [Hall B experimental program, usesDetector, CLAS detector]

Target entity: CLAS detector
Context triple: [Hall B experimental program, usesDetector, CLAS detector]
  • A. CLAS detector in Hall B chosen
    The CLAS detector in Hall B is a large-acceptance spectrometer at Jefferson Lab used to study the structure of nucleons and nuclei through high-precision electron scattering experiments.
  • B. DØ detector
    The DØ detector is a large particle physics experiment at Fermilab’s Tevatron collider designed to study high-energy proton–antiproton collisions and probe fundamental particles and forces.
  • C. RICH detector
    The RICH detector is a ring-imaging Cherenkov device used in the NA62 experiment at CERN to identify charged particles by measuring the Cherenkov light they emit.
  • D. Silicon Strip Detector
    A Silicon Strip Detector is a type of semiconductor particle detector that uses parallel strips of silicon to precisely measure the position and trajectory of charged particles in high-energy physics experiments.
  • E. BaBar detector
    The BaBar detector was a large particle physics experiment at the SLAC National Accelerator Laboratory designed to study B-meson decays and CP violation in high-energy electron–positron collisions.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
