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: Super-Kamiokande neutrino observatory | Statement: [Super-Kamiokande Collaboration, operates, Super-Kamiokande neutrino observatory]

Target entity: Super-Kamiokande neutrino observatory
Context triple: [Super-Kamiokande Collaboration, operates, Super-Kamiokande neutrino observatory]
  • A. 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.
  • B. K2K experiment
    The K2K experiment was a long-baseline neutrino experiment in Japan that sent a beam of muon neutrinos from KEK to the Super-Kamiokande detector, providing early accelerator-based evidence for neutrino oscillations.
  • C. Sudbury Neutrino Observatory
    The Sudbury Neutrino Observatory is a deep underground Canadian physics facility that made landmark measurements of solar neutrinos, providing key evidence for neutrino oscillations and mass.
  • D. 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.
  • E. Homestake solar neutrino experiment
    The Homestake solar neutrino experiment was a pioneering underground radiochemical detector in South Dakota that first measured solar neutrinos and revealed the solar neutrino problem, leading to major advances in neutrino physics.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
