WebJun 1, 2024 · The Boolean semiring \(\mathbb {B}=(\{0,1\},\vee ,\wedge ,0,1)\) is the domain of standard logical truth values. The semiring \(\mathbb {N}=(\mathbb {N},+,\cdot ,0,1)\) can be used for counting successful strategies for query evaluation. It also plays an important role for bag semantics in databases. Webon both sides over box .Acommutative semiring is a semiring in which the operator is commutative. A commutative semiring R is idempotent if a a = a, for all a ∈ R. A Boolean set BL =({0,1},∨,0,∧,1) with the logic operator OR (∨) and the logic operator AND (∧)isa commutative idempotent semiring. Define a set B¯n L as the
