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: Bott–Duffin inverse | Statement: [Raoul Bott, knownFor, Bott–Duffin inverse]

Target entity: Bott–Duffin inverse
Context triple: [Raoul Bott, knownFor, Bott–Duffin inverse]
  • A. Moore–Penrose inverse (precursor ideas)
    The Moore–Penrose inverse (precursor ideas) refers to E. H. Moore’s early foundational work on generalized matrix inverses, which laid the groundwork for the modern concept of the Moore–Penrose pseudoinverse.
  • B. Wiener–Hopf equations
    Wiener–Hopf equations are integral equations that arise in problems of filtering, prediction, and diffraction, forming the mathematical foundation for optimal linear filters such as the Wiener filter.
  • C. Banach inverse mapping theorem
    The Banach inverse mapping theorem is a fundamental result in functional analysis stating that a bijective bounded linear operator between Banach spaces has a bounded linear inverse.
  • D. Cauchy–Binet formula
    The Cauchy–Binet formula is a fundamental result in linear algebra that expresses the determinant of a product of two rectangular matrices as a sum of products of determinants of their square submatrices.
  • E. Bartels–Stewart algorithm
    The Bartels–Stewart algorithm is a numerical linear algebra method that efficiently solves certain matrix equations, particularly Sylvester and Lyapunov equations, using Schur decompositions.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
