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).

Target entity: T2K experiment Context triple: [J-PARC neutrino beamline, usedFor, T2K experiment]
-
A.
T2K
chosen
T2K is a long-baseline neutrino oscillation experiment in Japan that studies how neutrinos change type as they travel from J-PARC to the Super-Kamiokande detector.
-
B.
K2K experiment
The K2K experiment was a long-baseline neutrino experiment in Japan that sent a beam of muon neutrinos from KEK to the Super-Kamiokande detector, providing early accelerator-based evidence for neutrino oscillations.
-
C.
Super-Kamiokande neutrino observatory
The Super-Kamiokande neutrino observatory is a large underground water Cherenkov detector in Japan designed to study neutrinos from the Sun, atmosphere, supernovae, and other cosmic sources, and to investigate neutrino oscillations and proton decay.
-
D.
MINOS experiment
The MINOS experiment is a long-baseline neutrino oscillation project that studied how neutrinos change type as they travel from Fermilab to a distant underground detector.
-
E.
Kamiokande experiment
The Kamiokande experiment was a pioneering Japanese neutrino observatory that provided key evidence for solar and atmospheric neutrinos, contributing to the discovery of neutrino oscillations.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (2 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.
