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).

Target entity: Global Boundary Stratotype Section and Point (GSSP) used for stage limits
Context triple: [Late Triassic, stratigraphicBoundaryDefinition, Global Boundary Stratotype Section and Point (GSSP) used for stage limits]
  • A. Global Boundary Stratotype Section and Point chosen
    The Global Boundary Stratotype Section and Point (GSSP) is an internationally agreed reference point in a specific rock sequence that precisely defines the lower boundary of a stage or age in the geologic time scale.
  • B. Global Boundary Stratotype Section and Point for base of Hettangian
    The Global Boundary Stratotype Section and Point for the base of the Hettangian is the internationally agreed geological reference point that marks the formal beginning of the Jurassic Period and the Mesozoic era’s post-Triassic recovery interval.
  • C. Global Boundary Stratotype Section and Point at Klonk, Czech Republic
    The Global Boundary Stratotype Section and Point at Klonk in the Czech Republic is a formally designated geological reference site that marks the internationally agreed base of the Devonian System and serves as a key standard for correlating Early Devonian rock strata worldwide.
  • D. International Chronostratigraphic Chart
    The International Chronostratigraphic Chart is the globally recognized standard timeline used by geologists to define and correlate the divisions of Earth’s geological history.
  • E. Kellwasser horizons
    The Kellwasser horizons are distinctive black shale layers in Late Devonian marine sediments that mark one of the major extinction pulses during the Late Devonian mass extinction.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
PD Predicate disambiguation gpt-5-mini-2025-08-07 
Target predicate: stratigraphicBoundaryDefinition
Context triple: [Late Triassic, stratigraphicBoundaryDefinition, Global Boundary Stratotype Section and Point (GSSP) used for stage limits]
  • A. globalBoundaryStratotypeSectionAndPoint chosen
    Indicates the formally designated reference point and stratigraphic section that define the global boundary between two geological time units.
  • B. GSSPBaseDefinedBy
    Indicates that a GSSP (Global Stratotype Section and Point) base is formally established or characterized according to a specific defining criterion, boundary, or reference.
  • C. plateBoundaryBetween
    Indicates a geological relationship where a boundary exists between two tectonic plates.
  • D. hasStratigraphicPosition
    Indicates the relative position of one geological layer or unit within a stratigraphic sequence in relation to another.
  • E. climateBoundaryBetween
    Indicates a boundary or dividing line between two regions that differ in climate characteristics or classifications.
  • F. None of above.

Provenance (4 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.
