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: Post correspondence problem | Statement: [Computability and Unsolvability, topic, Post correspondence problem]

Target entity: Post correspondence problem Context triple: [Computability and Unsolvability, topic, Post correspondence problem]
-
A.
Post correspondence problem
chosen
The Post correspondence problem is a classic undecidable decision problem in theoretical computer science and mathematical logic that plays a central role in demonstrating the limits of algorithmic computability.
-
B.
Entscheidungsproblem
The Entscheidungsproblem is a foundational decision problem in mathematical logic that asks whether there exists a general algorithm to determine the truth or falsity of any given first-order logical statement.
-
C.
Halting problem
The halting problem is a fundamental decision problem in computability theory that asks whether a given program will eventually stop running or continue to run forever, and is famously proven to be undecidable.
-
D.
Computability and Unsolvability
Computability and Unsolvability is a classic 1958 textbook by Martin Davis that systematically develops the theory of computable functions and undecidable problems, helping to shape modern computability theory.
-
E.
Finite Automata and Their Decision Problems
"Finite Automata and Their Decision Problems" is a landmark 1959 paper by Dana Scott and Michael Rabin that founded the modern theory of finite automata and formalized key decision problems in automata theory and computation.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 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.
