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).

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Sun–Earth L2 Lagrange point
Context triple: [Low Frequency Instrument, placedAt, Sun–Earth L2 Lagrange point]
  • A. Sun–Earth L2 chosen
    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.
  • B. 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.
  • C. Earth–Moon L2 point
    The Earth–Moon L2 point is a gravitationally stable location beyond the Moon where the combined gravity of Earth and the Moon allows spacecraft to maintain a relatively fixed position with minimal fuel.
  • D. 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.
  • E. Earth–Moon Lagrange region
    The Earth–Moon Lagrange region comprises the gravitationally stable and semi-stable points in the Earth–Moon system where spacecraft can maintain position with minimal fuel, making it valuable for observation, navigation, and future space infrastructure.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.

Provenance (3 batches)

The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
