CL2 Structural Semantics

Structural Semantics of Common Logic (Edition 2) for Implementation in OntoMaven: Algebraic Structures and Algorithms


This talk presents a mathematical algorithm for importation resolution together with conversion into a canonical form for the ISO Common Logic (Edition 2) language (CL2). Proof that the transformations applied within this algorithm are semantics-preserving rests on the properties of algebraic structures generated as quotients of the $\Omega$-semigroup of corpora (sets of CL2 texts) under set union with domain-restriction operators. A nested sequence of quotients is obtained by considering congruence relations corresponding to increasing enforcement of CL2 semantics constraints.
