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: Alfvén waves | Statement: [Hannes Alfvén, notableWork, Alfvén waves]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Alfvén waves
Context triple: [Hannes Alfvén, notableWork, Alfvén waves]
  • A. Commission H – Waves in Plasmas
    Commission H – Waves in Plasmas is a specialized body within the International Union of Radio Science that focuses on the study and advancement of wave phenomena in plasmas and related space and laboratory environments.
  • B. Kelvin–Helmholtz instability
    Kelvin–Helmholtz instability is a fluid dynamical phenomenon in which velocity shear between layers of fluid (or plasma) with different densities leads to characteristic wave-like billows and turbulent mixing at their interface.
  • C. Kruskal–Shafranov instability criterion
    The Kruskal–Shafranov instability criterion is a fundamental condition in plasma physics that predicts when a magnetically confined plasma column becomes unstable to kink-like distortions.
  • D. Jeans instability
    Jeans instability is a gravitational phenomenon in astrophysics where regions within a gas cloud become unstable and collapse under their own gravity, leading to the formation of structures like stars and galaxies.
  • E. Holmboe instability
    Holmboe instability is a type of shear-driven wave instability that occurs in stably stratified fluids, producing characteristic interfacial waves and mixing at density interfaces.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
