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: SPIN model checker | Statement: [Gerard J. Holzmann, knownFor, SPIN model checker]

Target entity: SPIN model checker
Context triple: [Gerard J. Holzmann, knownFor, SPIN model checker]
  • A. Model Checking (book)
    "Model Checking" is a foundational textbook that systematically presents the theory and practice of using automated verification techniques to prove correctness properties of hardware and software systems.
  • B. PRISM probabilistic model checker
    PRISM probabilistic model checker is a formal verification tool used to model, analyze, and verify systems that exhibit probabilistic behavior, such as randomized algorithms and communication or security protocols.
  • C. Symbolic Model Checking
    Symbolic Model Checking is a formal verification technique that uses symbolic representations, such as binary decision diagrams, to efficiently verify properties of hardware and software systems with very large state spaces.
  • D. FDR model checker
    FDR model checker is a refinement-based verification tool used to analyze and prove properties of systems specified in the Communicating Sequential Processes (CSP) formalism.
  • E. NuSMV
    NuSMV is an open-source symbolic model checker designed for the formal verification of finite-state systems using temporal logic specifications.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
NEDg Description generation gpt-5.1
Instruction
Generate a one-sentence description of the target entity.
