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).

Target entity: H2 beam line Context triple: [North Area of CERN SPS, hasBeamLine, H2 beam line]
-
A.
M2 beam line
M2 beam line is a high-energy particle beam facility at CERN’s Super Proton Synchrotron used to deliver intense hadron and muon beams for fixed-target experiments such as COMPASS.
-
B.
CERN AWAKE experiment beamline
The CERN AWAKE experiment beamline is a dedicated facility at CERN that studies proton-driven plasma wakefield acceleration to develop next-generation high-gradient particle accelerators.
-
C.
CERN test beam lines
chosen
CERN test beam lines are specialized experimental facilities that deliver controlled particle beams to test and calibrate detectors and other high-energy physics instrumentation.
-
D.
Linac2
Linac2 was CERN’s long-serving linear accelerator that pre-accelerated protons for injection into the Proton Synchrotron Booster and the rest of the accelerator complex before being superseded by Linac4.
