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).

  • A. CERN Prevessin–Meyrin site
    The CERN Prevessin–Meyrin site is one of CERN’s main campuses on the French–Swiss border, hosting key accelerator and experimental facilities in the laboratory’s particle physics complex.
  • B. CERN control centre
    The CERN Control Centre is the central facility from which scientists and engineers operate and monitor CERN’s particle accelerators and associated experiments.
  • C. CERN data centre
    The CERN data centre is the primary computing and data storage facility of the European Organization for Nuclear Research, handling the massive data output from experiments like those at the Large Hadron Collider.
  • D. CERN accelerator complex
    The CERN accelerator complex is a network of interconnected particle accelerators and beamlines near Geneva that produce and prepare high-energy particle beams for experiments such as those at the Large Hadron Collider.
  • E. North Area of CERN SPS chosen
    The North Area of CERN’s Super Proton Synchrotron (SPS) is a major experimental zone hosting fixed-target high-energy physics experiments that use proton beams extracted from the SPS accelerator.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
