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).
Input
Phrase: CERN Beams Department | Statement: [Proton Synchrotron, managedBy, CERN Beams Department]

-
A.
North Area of CERN SPS
The North Area of CERN’s Super Proton Synchrotron (SPS) is a major experimental zone hosting fixed-target high-energy physics experiments that use proton beams extracted from the SPS accelerator.
-
B.
CERN accelerator complex
The CERN accelerator complex is a network of interconnected particle accelerators and beamlines near Geneva that produce and prepare high-energy particle beams for experiments such as those at the Large Hadron Collider.
-
C.
CERN
CERN is the European Organization for Nuclear Research, renowned for its large particle accelerators and fundamental physics experiments that have led to major discoveries such as the Higgs boson.
-
D.
LHC injector chain
The LHC injector chain is the sequence of accelerators and beamlines at CERN that progressively boost and prepare particle beams before they are injected into the Large Hadron Collider.
-
E.
CERN Large Hadron Collider surface facilities
The CERN Large Hadron Collider surface facilities are the above-ground buildings and infrastructure that support and control the LHC’s particle physics experiments near Geneva.

NEDg
Description generation
gpt-5.1
Instruction
Generate a one-sentence description of the target entity. You are given a context triple in the form (subject, predicate, object), where the object is the target entity. # Instructions Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. Avoid repeating the information from the triple, unless really essential. # Response Format Return only the sentence: "Description: [one-sentence description of the target entity]"
Input
Entity: CERN Beams Department Triple: [Proton Synchrotron, managedBy, CERN Beams Department]
Generated description
