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 halo orbit
Context triple: [Nancy Grace Roman Space Telescope, orbitType, Sun–Earth L2 halo orbit]
  • 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. Lissajous orbit
    A Lissajous orbit is a stable, looping three-dimensional trajectory around a Lagrange point, commonly used by space observatories to maintain a relatively constant position with respect to Earth and the Sun.
  • D. Earth-trailing orbit (STEREO-B)
    Earth-trailing orbit (STEREO-B) is the heliocentric path followed by NASA’s STEREO-B spacecraft as it slowly lags behind Earth to provide a unique vantage point for stereoscopic observations of the Sun.
  • E. Sun-synchronous orbit
    A Sun-synchronous orbit is a near-polar, low Earth orbit in which a satellite passes over any given point of the planet’s surface at the same local solar time, providing consistent lighting conditions for imaging and observation.
  • 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.
