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).

gpt-5-mini-2025-08-07
Target entity: Sun–Earth L2 via Herschel Space Observatory Context triple: [HIFI, observatoryOrbit, Sun–Earth L2 via Herschel Space Observatory]
-
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.
Gaia observatory
The Gaia observatory is a European Space Agency space telescope designed to create the most precise 3D map of the Milky Way by measuring the positions, distances, and motions of over a billion stars.
-
D.
Solar Orbiter mission
The Solar Orbiter mission is a European Space Agency-led spacecraft project designed to study the Sun up close, including its poles and heliosphere, to better understand solar activity and its effects on the solar system.
-
E.
Herschel Space Observatory
The Herschel Space Observatory was a European Space Agency space telescope that studied the universe in far-infrared and submillimetre wavelengths, revealing cold and dusty regions such as star-forming clouds and distant galaxies.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.

-
A.
orbitsObservedFrom
Indicates that the orbital motion of one object around another is being measured or recorded from a specific observation point or frame of reference.
-
B.
orbitalPosition
Indicates the relative location or path of one object in its orbit with respect to a central body or reference frame.
-
C.
orbitReference
chosen
Indicates that one entity serves as the orbital frame, path, or reference system relative to which another entity’s orbit is defined or described.
-
D.
orbitType
Indicates the specific kind or classification of an object's orbit in relation to the body it revolves around.
-
E.
orbitsBeyond
Indicates that one celestial body orbits at a greater average distance from a central object than another specified body.
- F. None of above.
Provenance (4 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.
