How this triple was built (4 steps)

Every LLM step that produced this triple, in pipeline order — named-entity classification, the disambiguation choices (the exact options shown, with the pick highlighted), and the generated description. The batch + timestamp of each is in the Provenance table below.

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: Linac4 | Statement: [CERN, operates, Linac4]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Linac4
Context triple: [CERN, operates, Linac4]
  • A. 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.
  • B. Oppenheimer–Phillips process
    The Oppenheimer–Phillips process is a nuclear reaction mechanism in which a deuteron interacting with a target nucleus effectively transfers its neutron while the proton is repelled, enabling certain reactions to occur at lower energies than would otherwise be required.
  • C. Baade Telescope
    The Baade Telescope is one of the twin 6.5-meter Magellan optical telescopes used for cutting-edge astronomical research in Chile.
  • D. Los Alamos Laboratory
    Los Alamos Laboratory was the secret U.S. research facility in New Mexico where the Manhattan Project developed the first atomic bombs during World War II.
  • E. MAUD Committee
    The MAUD Committee was a British scientific advisory group during World War II that conducted pioneering research into the feasibility of an atomic bomb, helping to spur the later development of the Manhattan Project.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
