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...
This paper gives an overview of two methods for automatically or semi-automatically generating deduction calculi from the semantic specification of a logic. One approach is based ...
Semantics represents a major problem area for active databases inasmuch as (i) there is l framework for defining the abstract semantics of active rules, and (ii) the various syst...
Using a call-by-value functional language as an example, this article illustrates the use of coinductive definitions and proofs in big-step operational semantics, enabling it to d...
In this paper, some fundamental aspects of the semantics of rule-based systems are sketched and related to the semantics of visual models. A rule-based system comprises a set of r...
