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.
IC3: Incremental Construction of Inductive Clauses for Indubitable Correctness
IC3: Incremental Construction of Inductive Clauses for Indubitable Correctness is a seminal model checking algorithm introduced by Kenneth McMillan that incrementally builds inductive invariants to efficiently verify hardware and software system correctness.
-
B.
Compositional model checking
Compositional model checking is a formal verification technique that proves system correctness by analyzing components separately and then combining the results, enabling scalable verification of complex systems.
-
C.
IC3 model checking algorithm
The IC3 model checking algorithm is a SAT-based formal verification technique that incrementally constructs inductive invariants to efficiently prove or refute safety properties of hardware and software systems.
-
D.
On reachability of hybrid automata
"On reachability of hybrid automata" is a foundational research paper in formal verification and hybrid systems theory that investigates algorithmic methods for determining whether certain states can be reached in systems combining discrete and continuous dynamics.
-
E.
Dijkstra weakest precondition calculus
Dijkstra weakest precondition calculus is a formal method for reasoning about program correctness by computing the weakest conditions that must hold before execution to guarantee a desired postcondition.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

Provenance (2 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
