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.
J-PARC
chosen
J-PARC (Japan Proton Accelerator Research Complex) is a high-intensity proton accelerator facility in Japan used for cutting-edge research in particle and nuclear physics, materials science, and related fields.
-
B.
J-PARC neutrino beamline
The J-PARC neutrino beamline is a high-intensity neutrino production facility in Japan that generates and directs neutrino beams for long-baseline experiments such as T2K.
-
C.
SPEAR storage ring
The SPEAR storage ring is an electron storage ring at SLAC National Accelerator Laboratory that historically served as both a particle physics collider and a synchrotron radiation source, forming the basis for later upgrades like SPEAR3.
-
D.
Fermilab Booster
Fermilab Booster is a rapid-cycling synchrotron at Fermilab that accelerates protons to intermediate energies before sending them to higher-energy accelerators and experiments.
-
E.
Proton Synchrotron Booster
The Proton Synchrotron Booster is a circular particle accelerator at CERN that increases the energy of protons from the linear accelerator before injecting them into larger synchrotrons in the accelerator complex.
- 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.
