Abstract. Hybrid knowledge bases (HKB’s) [11] were developed to provide formal models for the mediation of data and knowledge bases [14,15]. They are based on Generalized Annotat...
For a functional programming language with a lazy standard semantics, we define a strictness analysis by means of abstract interpretation. Using the information from the strictne...
The logic programming language framework Kernel Andorra Prolog is de ned by a formal computation model. In Kernel Andorra Prolog, general combinations of concurrent reactive langu...
