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).

Target entity: Hash-based Message Authentication Code
Context triple: [RFC 2104, defines, Hash-based Message Authentication Code]
  • A. Merkle–Damgård construction
    The Merkle–Damgård construction is a fundamental method for building collision-resistant cryptographic hash functions from fixed-size compression functions, used in many classic hash algorithms like MD5 and SHA-1.
  • B. Carter–Wegman MACs
    Carter–Wegman MACs are a family of message authentication codes that use universal hashing combined with a secret key to provide efficient and provably secure authentication.
  • C. Message-Digest Algorithm 5
    Message-Digest Algorithm 5 (MD5) is a widely known but now cryptographically broken hash function that produces a 128-bit hash value and was once commonly used for checksums and data integrity verification.
  • D. Secure Hash Standard
    The Secure Hash Standard is a U.S. federal standard that specifies secure hash algorithms (such as the SHA family) used for generating fixed-size cryptographic hashes to ensure data integrity and support digital signatures.
  • E. Whirlpool hash function
    Whirlpool is a cryptographic hash function designed by Vincent Rijmen and Paulo S. L. M. Barreto, known for its wide-pipe construction and strong security properties suitable for digital signatures and data integrity.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
