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).

  • A. ChaCha20
    ChaCha20 is a modern stream cipher designed by Daniel J. Bernstein, widely used for its high performance and strong security in protocols like TLS.
  • B. XChaCha20-Poly1305 AEAD construction
    XChaCha20-Poly1305 AEAD construction is an authenticated encryption scheme that extends ChaCha20-Poly1305 with a longer nonce for improved security and robustness against nonce reuse.
  • C. Salsa20
    Salsa20 is a high-speed stream cipher designed by Daniel J. Bernstein, widely used in modern cryptography for its strong security and efficient software performance.
  • D. SipHash24
    SipHash24 is a fast, cryptographically secure keyed hash function designed to protect hash tables from collision attacks while remaining efficient for short inputs.
  • E. Poly1305
    Poly1305 is a high-speed message authentication code (MAC) algorithm commonly used with stream ciphers like ChaCha20 to provide data integrity and authenticity.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
