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: Extended Kalman filter | Statement: [Markov localization, relatedTo, Extended Kalman filter]

-
A.
extended Kalman filter
chosen
The extended Kalman filter is a state estimation algorithm that generalizes the Kalman filter to nonlinear systems by linearizing about the current estimate, widely used in robotics and control for tracking and localization.
-
B.
Kalman filter
The Kalman filter is a mathematical algorithm used to estimate the changing state of a system from noisy measurements, widely applied in control systems, navigation, and signal processing.
-
C.
unscented Kalman filter
The unscented Kalman filter is a nonlinear state estimation algorithm that uses a deterministic sampling approach (sigma points) to more accurately capture the mean and covariance of a system than the standard extended Kalman filter.
-
D.
Sequential Monte Carlo Methods for Bayesian Filtering
"Sequential Monte Carlo Methods for Bayesian Filtering" is a scholarly work that develops and analyzes particle filtering techniques for performing Bayesian inference in dynamic systems.
-
E.
“A New Approach to Linear Filtering and Prediction Problems”
“A New Approach to Linear Filtering and Prediction Problems” is Rudolf E. Kálmán’s landmark 1960 paper that introduced the Kalman filter, a foundational algorithm for optimal estimation in control theory, signal processing, and navigation.
- F. None of above.
- 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.
