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: Sun–Earth L1 point | Statement: [Lissajous orbit, isUsedAt, Sun–Earth L1 point]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Sun–Earth L1 point
Context triple: [Lissajous orbit, isUsedAt, Sun–Earth L1 point]
  • A. Sun–Earth L1 Lagrange point chosen
    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.
  • 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. Lagrange points
    Lagrange points are specific positions in space where the gravitational forces of two large bodies and the orbital motion of a smaller object balance so that the smaller object can remain in a stable or semi-stable location relative to the two larger bodies.
  • 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-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.
  • 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.
