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: Baksan Neutrino Observatory | Statement: [SN 1987A, neutrinoDetectors, Baksan Neutrino Observatory]

Target entity: Baksan Neutrino Observatory
Context triple: [SN 1987A, neutrinoDetectors, Baksan Neutrino Observatory]
  • A. IceCube Neutrino Observatory
    The IceCube Neutrino Observatory is a massive, cubic-kilometer-scale neutrino detector embedded deep in Antarctic ice, designed to observe high-energy neutrinos from cosmic sources.
  • B. Borexino
    Borexino is a large liquid scintillator neutrino detector located at Italy’s Gran Sasso National Laboratory, designed to study low-energy solar and other neutrinos with extremely low background levels.
  • C. 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.
  • D. Sanford Underground Research Facility
    The Sanford Underground Research Facility is a deep underground laboratory in South Dakota that hosts major particle physics and astrophysics experiments, including serving as the far-site for the DUNE neutrino project.
  • E. LBNE experiment
    The LBNE (Long-Baseline Neutrino Experiment) was a proposed U.S.-based long-baseline neutrino physics project that laid the groundwork for what became the Deep Underground Neutrino Experiment (DUNE).
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
