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: Earth–Moon L2 point | Statement: [Lissajous orbit, isUsedAt, Earth–Moon L2 point]

Target entity: Earth–Moon L2 point
Context triple: [Lissajous orbit, isUsedAt, Earth–Moon L2 point]
  • A. Earth–Moon L1 point
    The Earth–Moon L1 point is a gravitational equilibrium location between Earth and the Moon where spacecraft can maintain a relatively stable position with minimal fuel, often using Lissajous or halo orbits for observation or transfer missions.
  • B. Sun–Earth L2
    Sun–Earth L2 is a gravitationally stable point in space located beyond Earth's orbit where the combined gravity of the Sun and Earth allows spacecraft, such as the James Webb Space Telescope, to maintain a relatively constant position with minimal fuel use.
  • C. Sun–Earth L1 Lagrange point
    The Sun–Earth L1 Lagrange point is a gravitationally stable location between the Earth and the Sun where spacecraft can maintain a relatively fixed position with minimal fuel, ideal for continuous solar and space weather observations.
  • D. Earth–Moon barycenter
    The Earth–Moon barycenter is the common center of mass around which both Earth and the Moon orbit in their mutual gravitational interaction.
  • E. Earth–Moon system
    The Earth–Moon system is the gravitationally bound pair of our planet and its natural satellite, whose mutual interactions shape tides, eclipses, and the dynamical evolution of both bodies.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
