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).

-
A.
first binary pulsar PSR B1913+16
chosen
PSR B1913+16 is a landmark binary pulsar system whose precisely measured orbital decay provided the first strong indirect evidence for the existence of gravitational waves, leading to a Nobel Prize in Physics.
-
B.
International Pulsar Timing Array
The International Pulsar Timing Array is a global collaboration of radio observatories that precisely monitor millisecond pulsars to detect low-frequency gravitational waves and study fundamental physics.
-
C.
first millisecond pulsar PSR B1937+21
PSR B1937+21 is the first-discovered millisecond pulsar, a rapidly rotating neutron star that spins hundreds of times per second and serves as a key object in the study of extreme astrophysical environments and precise cosmic timing.
-
D.
Gravity Probe B experiment
Gravity Probe B experiment was a NASA-led satellite mission designed to precisely measure how Earth's gravity warps space and time, providing a high-accuracy test of key predictions of Einstein's general relativity.
-
E.
Pound–Rebka experiment
The Pound–Rebka experiment was a landmark 1959 physics test that measured the gravitational redshift of gamma rays in Earth’s gravitational field, providing one of the first precise terrestrial confirmations of general relativity.
- 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.
