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.
MERRA reanalysis system
chosen
The MERRA reanalysis system is a NASA atmospheric reanalysis project that uses the Goddard Earth Observing System models to produce a long-term, consistent record of global weather and climate data.
-
B.
Global Data-processing and Forecasting System
The Global Data-processing and Forecasting System is an international meteorological infrastructure that collects, processes, and distributes weather and climate data to support global forecasting and early warning services.
-
C.
Integrated Forecasting System
The Integrated Forecasting System is the European Centre for Medium-Range Weather Forecasts’ advanced global numerical weather prediction model used to produce medium- and long-range weather forecasts.
-
D.
ECMWF Ensemble Prediction System
The ECMWF Ensemble Prediction System is a global numerical weather prediction framework that runs multiple forecast simulations to quantify atmospheric uncertainty and provide probabilistic weather guidance.
-
E.
Goddard Earth Observing System models
The Goddard Earth Observing System models are a suite of advanced atmospheric and Earth system models used for global weather, climate, and data assimilation research and forecasting.
- 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.
