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: SHA-2 | Statement: [Merkle–Damgård construction, usedIn, SHA-2]

Target entity: SHA-2
Context triple: [Merkle–Damgård construction, usedIn, SHA-2]
  • A. SHA-256
    SHA-256 is a widely used cryptographic hash function from the SHA-2 family that produces a 256-bit hash value for securing data integrity and authentication.
  • B. RIPEMD-160
    RIPEMD-160 is a 160-bit cryptographic hash function designed as an alternative to SHA-1, commonly used for data integrity and security applications.
  • C. 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.
  • D. SHA
    SHA is the IATA airport code for Shanghai Hongqiao International Airport, a major domestic and regional aviation hub serving Shanghai, China.
  • E. SHA
    SHA is the commonly used abbreviation for the School of Hospitality Administration, an academic institution focused on hospitality and related fields.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
