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: Über den Nachweis und das Verhalten der bei der Bestrahlung des Urans mittels Neutronen entstehenden Erdalkalimetalle | Statement: [Meitner–Hahn experiments, publication, Über den Nachweis und das Verhalten der bei der Bestrahlung des Urans mittels Neutronen entstehenden Erdalkalimetalle]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Über den Nachweis und das Verhalten der bei der Bestrahlung des Urans mittels Neutronen entstehenden Erdalkalimetalle
Context triple: [Meitner–Hahn experiments, publication, Über den Nachweis und das Verhalten der bei der Bestrahlung des Urans mittels Neutronen entstehenden Erdalkalimetalle]
  • A. Meitner–Hahn experiments
    The Meitner–Hahn experiments were pioneering nuclear physics investigations in the 1930s that led to the discovery and explanation of nuclear fission in uranium.
  • B. Meitner–Frisch interpretation of fission
    The Meitner–Frisch interpretation of fission is the 1939 theoretical explanation by Lise Meitner and Otto Frisch that identified nuclear fission as the splitting of heavy atomic nuclei with a corresponding release of enormous energy, laying the groundwork for nuclear physics and atomic energy.
  • C. The Neutron (1932 paper)
    The Neutron (1932 paper) is James Chadwick’s landmark publication that announced and characterized the neutron, fundamentally reshaping nuclear physics and earning him the Nobel Prize in Physics.
  • D. Mechanik der Atomkerne
    Mechanik der Atomkerne is a foundational physics text on the theory and structure of atomic nuclei, co-authored by Nobel laureate Hans D. Jensen.
  • E. Frisch–Peierls memorandum
    The Frisch–Peierls memorandum was a pivotal 1940 document by physicists Otto Frisch and Rudolf Peierls that first outlined the feasibility of a small, practical uranium-based atomic bomb, helping to catalyze British and later Allied nuclear weapons research.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
