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: Grad moment expansion | Statement: [Harold Grad, notableConcept, Grad moment expansion]

Target entity: Grad moment expansion
Context triple: [Harold Grad, notableConcept, Grad moment expansion]
  • A. On Estimation of a Probability Density Function and Mode
    "On Estimation of a Probability Density Function and Mode" is a seminal statistical paper by Emanuel Parzen that develops kernel-based methods for nonparametric density and mode estimation.
  • B. Gabor filter
    A Gabor filter is a linear filter used in image processing and computer vision that analyzes spatial frequency content in specific directions and scales, making it useful for texture analysis and feature extraction.
  • C. Lucas–Kanade optical flow algorithm
    The Lucas–Kanade optical flow algorithm is a widely used computer vision method for estimating the motion of features between consecutive images by assuming locally constant motion and solving a least-squares problem.
  • D. Horn–Schunck optical flow method
    The Horn–Schunck optical flow method is a classic global variational approach in computer vision that estimates dense motion fields between image frames by enforcing both brightness constancy and smoothness constraints.
  • E. Modeling image patches with a directed hierarchy of Markov random fields
    "Modeling image patches with a directed hierarchy of Markov random fields" is a research paper that introduces a probabilistic hierarchical model for capturing complex statistical structure in image patches using directed Markov random fields.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
