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.
drift tube linac (DTL)
chosen
A drift tube linac (DTL) is a type of linear particle accelerator that uses a series of electrically driven drift tubes to progressively increase the energy of charged particle beams.
-
B.
Linac4
Linac4 is a linear accelerator at CERN that serves as the first stage of the proton acceleration chain for the Large Hadron Collider and other experiments.
-
C.
Compact Linear Collider test facilities
The Compact Linear Collider test facilities are experimental research installations at CERN dedicated to developing and validating technologies for a future high-energy electron–positron linear collider.
-
D.
Antiproton Decelerator
The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
-
E.
Proton Synchrotron
The Proton Synchrotron is a historic circular particle accelerator at CERN that has played a key role in high-energy physics research and in feeding beams to larger colliders.
- 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.
