To support commonsense reasoning about space, we require a qualitative calculus of spatial entities and their relations. One requirement for such a calculus, which has not so far ...
We design and study νObj, a calculus and dependent type system for objects and classes which can have types as members. Type can be aliases, abstract types, or new types. The type...
This paper discusses the use of contextual reasoning, i.e. context transformation for achieving semantic interoperability in heterogeneous information systems. We introduce termino...
Bigraphical Reactive Systems have been proposed as a meta model for global ubiquitous computing generalising process calculi for mobility such as the pi-calculus and the Mobile Amb...
Abstract-- We consider a hybrid knowledge representation system for ontological knowledge bases in order to maintain knowledge consistency between taxonomic knowledge and assertion...
