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: Betti group | Statement: [Enrico Betti, notableWork, Betti group]

Target entity: Betti group
Context triple: [Enrico Betti, notableWork, Betti group]

• A. Betti numbers
  Betti numbers are topological invariants that count the number of independent cycles or holes in each dimension of a topological space, reflecting its underlying shape and structure.
• B. Picard group
  The Picard group is an algebraic invariant of a variety or scheme that classifies line bundles (or divisor classes) up to isomorphism, playing a central role in algebraic geometry.
• C. Betti
  Betti is a German diminutive given name, commonly used as a short form of Bettina.
• D. Grothendieck group
  The Grothendieck group is an algebraic construction that formally turns a commutative monoid (often arising from isomorphism classes of objects like vector bundles or modules) into an abelian group, playing a central role in K-theory and modern algebraic geometry.
• E. Alexander–Spanier cohomology
  Alexander–Spanier cohomology is a cohomology theory in algebraic topology defined using cochains on all finite subsets of a space, notable for its generality and close relationship to Čech and singular cohomology.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Betti group
Triple: [Enrico Betti, notableWork, Betti group]

A Betti group is an algebraic-topological invariant that captures the number of independent k-dimensional holes in a topological space, forming the basis for Betti numbers.
