In this paper, we define a simple but scalable framework for peer-to-peer data sharing systems, in which the problem of answering queries over a network of semantically related p...
We introduce a class of coalgebraic models and a family of modal logics that support the specication of spatial properties of distributed applications. The evaluation of a formul...
The paper provides a recipe for adequately representing a very inclusive class of finite-valued logics by way of tableaux. The only requisite for applying the method is that the o...
Proof-carrying code (PCC) is a general framework that can, in principle, verify safety properties of arbitrary machine-language programs. Existing PCC systems and typed assembly l...
Social networks play important roles in the Semantic Web: knowledge management, information retrieval, ubiquitous computing, and so on. We propose a social network extraction syst...
