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).

Target entity: Sun–Earth L1 point halo orbit Context triple: [NISTAR, orbits, Sun–Earth L1 point halo orbit]
-
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.
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.
Clarke orbit
A Clarke orbit is a geostationary orbit directly above Earth's equator where a satellite appears fixed over one point on the surface, enabling continuous communication coverage.
- 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.
