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: Hodge–de Rham complex | Statement: [Hodge Laplacian, associatedWith, Hodge–de Rham complex]

Context triple: [Hodge Laplacian, associatedWith, Hodge–de Rham complex]
  • A. Čech–de Rham complex
    The Čech–de Rham complex is a double complex that combines Čech cochains with differential forms to compute de Rham cohomology via open covers.
  • B. Hodge decomposition
    Hodge decomposition is a fundamental result in differential geometry and Hodge theory that expresses differential forms on a Riemannian manifold uniquely as sums of exact, co-exact, and harmonic components.
  • C. Hodge structure
    A Hodge structure is an algebraic structure on the cohomology of complex algebraic varieties that decomposes it into pieces reflecting both complex and topological properties, central to Hodge theory in algebraic geometry.
  • D. Hodge Laplacian
    The Hodge Laplacian is a differential operator on differential forms of a Riemannian manifold that combines the exterior derivative and its adjoint to study harmonic forms and de Rham cohomology.
  • E. de Rham cohomology
    de Rham cohomology is a cohomology theory for smooth manifolds that uses differential forms to capture their global topological and geometric properties.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
