Given a first-order sentence, a model-checking computation tests whether the sentence holds true in a given finite structure. Data provenance extracts from this computation an abstraction of the manner in which its result depends on the data items that describe the model. Previous work on provenance was, to a large extent, restricted to the negation-free fragment of first-order logic and showed how provenance abstractions can be usefully described as elements of commutative semirings --- most generally as multivariate polynomials with positive integer coefficients. In this paper we introduce a novel approach to dealing with negation and a corresponding commutative semiring of polynomials with dual indeterminates. These polynomials are used to perform reverse provenance analysis, i.e., finding models that satisfy various properties under given provenance tracking assumptions.

Codd's Theorem for Databases over Semirings
Codd's theorem, the equivalence of relational algebra and relational calculus, is extended to semiring-annotated databases, with a proof that division is not expressible from the five basic operations over bag databases.

Rewriting Consistent Answers on Annotated Data
Consistent answers of self-join-free conjunctive queries over naturally ordered positive semirings are rewritable in the logic LK exactly when the query's attack graph is acyclic, generalizing the Boolean case.

Provenance Analysis and Semiring Semantics for First-Order Logic
Dual-indeterminate polynomial semirings provide a provenance semantics for full first-order logic with negation, enabling reverse provenance analysis and repair computation.
