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

Target entity: Thomson cross section
Context triple: [CODATA recommended values of the fundamental physical constants, includesConstant, Thomson cross section]
  • A. Klein–Nishina formula
    The Klein–Nishina formula is a fundamental result in quantum electrodynamics that gives the differential cross section for Compton scattering of photons by free electrons, incorporating relativistic and quantum effects.
  • B. Compton effect
    The Compton effect is the increase in wavelength (and corresponding decrease in energy) of X-rays or gamma rays when they scatter off electrons, providing key evidence for the particle nature of light.
  • C. Bethe formula for stopping power
    The Bethe formula for stopping power is a fundamental equation in particle physics that quantifies the energy loss of fast charged particles as they pass through matter.
  • D. Schwinger effect
    The Schwinger effect is a quantum field theory phenomenon in which extremely strong electric fields can spontaneously create particle–antiparticle pairs from the vacuum.
  • E. TOTal Elastic and diffractive cross section Measurement
    TOTal Elastic and diffractive cross section Measurement (TOTEM) is a CERN experiment at the Large Hadron Collider dedicated to precisely measuring proton–proton total, elastic, and diffractive cross sections at high energies.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
