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.
