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).
Input
Phrase: UA2 experiment | Statement: [W− boson, discoveryCreditedTo, UA2 experiment]

Target entity: UA2 experiment Context triple: [W− boson, discoveryCreditedTo, UA2 experiment]
-
A.
UA2 experiment
chosen
The UA2 experiment was a high-energy physics collaboration at CERN’s Super Proton Synchrotron that played a key role in confirming the existence and properties of the W boson.
-
B.
UA1 experiment
The UA1 experiment was a high-energy physics collaboration at CERN’s Super Proton Synchrotron that became famous for providing the first experimental evidence of the W and Z bosons, key carriers of the weak nuclear force.
-
C.
ATRAP experiment
The ATRAP experiment is a particle physics project at CERN dedicated to trapping and studying antihydrogen atoms and other antimatter systems to test fundamental symmetries and the properties of antimatter.
-
D.
ALPHA experiment
The ALPHA experiment is a CERN-based research project that studies antihydrogen atoms to test fundamental symmetries between matter and antimatter.
-
E.
AEgIS experiment
The AEgIS experiment is a CERN-based research project that studies how antimatter, specifically antihydrogen, behaves under gravity to test the weak equivalence principle.
- 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.
