Triple

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).

Phrase: Riemann zeta function | Statement: [Voronin universality theorem, mainObject, Riemann zeta function]

Target entity: Riemann zeta function
Context triple: [Voronin universality theorem, mainObject, Riemann zeta function]

• A. Riemann zeta function chosen
  The Riemann zeta function is a complex-valued function central to analytic number theory, whose properties—especially the distribution of its zeros—are deeply connected to the distribution of prime numbers.
• B. Riemann xi function
  The Riemann xi function is an entire, symmetrized version of the Riemann zeta function that encodes its nontrivial zeros and plays a central role in the study of the Riemann Hypothesis and related analytic number theory.
• C. Riemann–Siegel formula
  The Riemann–Siegel formula is an asymptotic expression that efficiently approximates the Riemann zeta function on the critical line, playing a key role in the numerical study of its zeros.
• D. Riemann–Siegel theta function
  The Riemann–Siegel theta function is a special function that appears in the study of the Riemann zeta function, used to express its values on the critical line in a form suitable for high-precision numerical computation.
• E. Dirichlet eta function
  The Dirichlet eta function is an alternating Dirichlet series closely related to the Riemann zeta function and used in analytic number theory, particularly for studying series convergence and analytic continuation.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target predicate: mainObject
Context triple: [Voronin universality theorem, mainObject, Riemann zeta function]

• A. mainBase
  Indicates that one entity serves as the primary or central base or headquarters for another entity.
• B. mainFunctions chosen
  Indicates that the subject serves as the primary or central functional component or role for the object.
• C. mainSingle
  Indicates that an entity is the primary or sole main instance among a set of related entities.
• D. mainRite
  Indicates that one ritual, ceremony, or rite is the primary or central rite associated with a given context, entity, or event.
• E. mainStartingPoint
  Indicates the primary location or position from which an event, process, or path begins.
• F. None of above.
