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

Target entity: Lebesgue measure zero set
Context triple: [Lebesgue differentiation theorem, usesConcept, Lebesgue measure zero set]
  • A. Lebesgue measurable set
    A Lebesgue measurable set is a subset of Euclidean space for which a consistent, translation-invariant notion of "size" (Lebesgue measure) can be assigned, forming the foundation of modern measure theory and integration.
  • B. Lebesgue measure
    Lebesgue measure is the standard way of assigning a consistent notion of "length," "area," or "volume" to subsets of Euclidean space, forming the foundation of modern measure theory and integration.
  • C. Carathéodory measurability criterion
    The Carathéodory measurability criterion is a fundamental condition in measure theory that characterizes measurable sets via an outer measure by requiring additivity over intersections and complements.
  • D. Nikodym set
    A Nikodym set is a pathological subset of the plane in geometric measure theory that intersects almost every line in a very small (often measure-zero) way while still having full measure in a region, illustrating extreme irregular behavior of measurable sets.
  • E. Borel set
    A Borel set is any set that can be formed from open (or equivalently closed) sets of a topological space through countable unions, intersections, and complements, forming the smallest σ-algebra containing all open sets.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Lebesgue measure zero set
Target entity description: A Lebesgue measure zero set is a subset of Euclidean space that can be covered by intervals of arbitrarily small total length, making its "size" negligible in the sense of Lebesgue measure.

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.
