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: Givens rotations | Statement: [Bidiagonal matrix, isUsedWith, Givens rotations]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Givens rotations
Context triple: [Bidiagonal matrix, isUsedWith, Givens rotations]
  • A. Householder transformation
    The Householder transformation is a linear algebra technique that uses reflections to orthogonally transform vectors and matrices, commonly employed in QR decomposition and numerical algorithms.
  • B. rotation group SO(3)
    The rotation group SO(3) is the group of all rotations in three-dimensional space, represented by 3×3 orthogonal matrices with determinant 1, and plays a central role in classical mechanics, quantum mechanics, and geometry.
  • C. Schmidt orthogonalization
    Schmidt orthogonalization is a mathematical procedure, also known as the Gram–Schmidt process, that converts a set of linearly independent vectors into an orthonormal set spanning the same subspace.
  • D. rotation group SU(2)
    The rotation group SU(2) is the Lie group of 2×2 unitary matrices with determinant 1 that serves as the double cover of the three-dimensional rotation group SO(3) and underlies the quantum theory of angular momentum and spin.
  • E. Jacobi eigenvalue algorithm
    The Jacobi eigenvalue algorithm is an iterative numerical method for computing all eigenvalues and eigenvectors of a real symmetric matrix by applying a sequence of orthogonal similarity transformations.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
