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: Nyquist frequency | Statement: [Harry Nyquist, hasConceptNamedAfter, Nyquist frequency]

Target entity: Nyquist frequency Context triple: [Harry Nyquist, hasConceptNamedAfter, Nyquist frequency]
-
A.
Nyquist theorem
The Nyquist theorem is a fundamental principle in signal processing that states a continuous signal can be perfectly reconstructed from its samples if it is sampled at more than twice its highest frequency component.
-
B.
Nyquist
Nyquist is a surname most famously associated with Swedish-American engineer Harry Nyquist, known for his foundational contributions to information theory and telecommunications.
-
C.
Nyquist plot
The Nyquist plot is a graphical representation used in control engineering and signal processing to assess the stability and frequency response of linear time-invariant systems by plotting complex gain as a function of frequency.
-
D.
Parseval's theorem
Parseval's theorem is a fundamental result in Fourier analysis that equates the total energy of a function in the time (or spatial) domain with the total energy of its representation in the frequency domain.
-
E.
Nyquist stability criterion
The Nyquist stability criterion is a graphical frequency-domain method in control theory used to determine the stability of feedback systems by analyzing how their open-loop transfer function encircles a critical point in the complex plane.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
NEDg
Description generation
gpt-5.1
Instruction
Generate a one-sentence description of the target entity. You are given a context triple in the form (subject, predicate, object), where the object is the target entity. # Instructions Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. Avoid repeating the information from the triple, unless really essential. # Response Format Return only the sentence: "Description: [one-sentence description of the target entity]"
Input
Entity: Nyquist frequency Triple: [Harry Nyquist, hasConceptNamedAfter, Nyquist frequency]
Generated description
The Nyquist frequency is the highest signal frequency that can be accurately sampled without aliasing, equal to half the sampling rate in digital signal processing.
