We introduce a formal language for multi-agent systems based on new modal operators. The modal operators express concurrency at the syntactic level. Operators containing quantifie...
—We propose a mathematical framework for step indexed realizability semantics of a call-by-value polymorphic lambda calculus with recursion, existential types and recursive types...
Existing solutions to data and schema integration require user interaction/input to generate a data transformation between two different schemas. These approaches are not appropri...
Building on a simple modal logic of context, the paper presents a dynamic logic characterizing operations of contraction and expansion on theories. We investigate the mathematical...

Abstract. Time is omnipresent on the (Semantic) Web. However, formalism like XML, XML Schema, RDF, OWL and (Semantic) Web query languages have, if any, only very limited notions of...
