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.
Proton Improvement Plan
chosen
The Proton Improvement Plan is a Fermilab accelerator upgrade initiative designed to significantly increase the intensity and reliability of the laboratory’s proton beam for high-energy physics experiments.
-
B.
LHC Injectors Upgrade (LIU)
The LHC Injectors Upgrade (LIU) is a major CERN project to modernize and enhance the performance of the accelerator chain feeding the Large Hadron Collider, enabling higher beam intensities and luminosities for future physics runs.
-
C.
PEP-II storage ring
The PEP-II storage ring was an asymmetric-energy electron–positron collider at SLAC designed to produce large numbers of B mesons for precision studies of CP violation and other aspects of particle physics.
-
D.
Fermilab Recycler Ring
The Fermilab Recycler Ring is a storage and cooling ring in the Fermilab accelerator complex used to accumulate and prepare high-intensity proton beams for further acceleration and experiments.
-
E.
SPS Heavy Ion and Neutrino Experiment
The SPS Heavy Ion and Neutrino Experiment (NA61/SHINE) is a fixed-target particle physics experiment at CERN’s Super Proton Synchrotron that studies hadron production in proton, pion, and ion collisions for strong-interaction physics and neutrino beam characterization.
- 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.
