  Semiring semantics for first-order logic provides a way to trace how facts
represented by a model are used to deduce satisfaction of a formula. Team
semantics is a framework for studying logics of dependence and independence in
diverse contexts such as databases, quantum mechanics, and statistics by
extending first-order logic with atoms that describe dependencies between
variables. Combining these two, we propose a unifying approach for analysing
the concepts of dependence and independence via a novel semiring team
semantics, which subsumes all the previously considered variants for
first-order team semantics. In particular, we study the preservation of
satisfaction of dependencies and formulae between different semirings. In
addition we create links to reasoning tasks such as provenance, counting, and
repairs.
