The paper provides a uniform representation of abductive reasoning in the logical framework of causal inference relations. The representation covers in a single framework not only...
Controlled Query Evaluation (CQE) is a logical framework for the protection of secrets in databases. In this article, we extend the CQE framework to possibilistic logic: knowledge ...
Abstract. A brief overview is given of recent results on theory revision with queries for propositional formulas, such as monotone and unate DNF, Horn formulas, read-once formulas,...
LOTOS is a formal specification language, designed for the precise description of open distributed systems and protocols. Our purpose is to introduce the operators of logics (for e...
Abstract. Logical architectures combine several logics into a more complex logical system. In this paper we study a logical architecture using input/output operations corresponding...
