Semantic Processing of the Semantic Web [chapter]

Kunal Patel, Gopal Gupta
2003 Lecture Notes in Computer Science  
The semantics of both the resource description languages and the query languages are executable and when put together can be used to compute answers to semantic web queries.  ...  The main advantage of this semantic-based approach to processing the semantic web is that these executable semantics can be developed extremely quickly.  ...  By assigning internal ids, higher order statements can be represented in Horn logic.  ...

Animation of Z Specifications By Translation to Prolog

2000 Doğuş Üniversitesi Dergisi  
However, in order to be validated the Z specification must be tested, and to achieve this it has to be transformed into a form that can be executed or animated.  ...  Formal methods of software development rely on the validation of the specification of the software. Such specification is normally expressed in a formal language such as Z.  ...  Direct execution is the m ost convenient method for animating formal specification statements. But as stated above, in order to do it, the formal specification language must be executable.  ...

Optimization of Executable Formal Interpreters developed in Higher-order Theorem Proving Systems [article]

Zheng Yang, Hang Lei
2018 arXiv   pre-print
In recent publications, we presented a novel formal symbolic process virtual machine (FSPVM) framework that combined higher-order theorem proving and symbolic execution for verifying the reliability and  ...  The present work addresses this issue by first identifying three root causes of the low execution efficiency of formal interpreters.  ...  As such, the fundamental environment provided by Coq is not sufficient to symbolically execute programs written by a mainstream higher-order programming language ℒ, and thereby obtain logic memory states  ...

On embedding a hardware description language in Isabelle/HOL

Wilayat Khan, David Sanan, Zhe Hou, Liu Yang
2019 Design automation for embedded systems  
In order to define executable hardware description language while at the same time be fit for formal proofs of properties, a hardware description language VeriFormal, embedded in Isabelle/HOL, was created  ...  Building such an environment is challenging due to the fact that the designer must have expertise in programming language design, the specific domain and theorem prover.  ...  [44] as the higher-order logic of Isabelle/HOL.  ...

FEther: An Extensible Definitional Interpreter for Smart-contract Verifications in Coq [article]

Zheng Yang, Hang Lei
2018 arXiv   pre-print
Combining symbolic execution with higher-order theorem-proving, it solves consistency, automation, and reusability problems by standard theorem-proving approaches.  ...  It supports almost all semantics of the Solidity programing language, and simultaneously executes multiple types of symbols.  ...  The properties of programs can be rigorously verified by proving higher-order logic theorems.  ...

Executing Higher Order Logic [chapter]

Stefan Berghofer, Tobias Nipkow
2002 Lecture Notes in Computer Science  
Specifications consisting of datatypes, recursive functions and inductive definitions are compiled into a functional program. Functions and inductively defined relations can be mixed.  ...  Inductive definitions must be such that they can be executed in Prolog style but requiring only matching rather than unification. This restriction is enforced by a mode analysis.  ...  Introduction Executing formal specifications has been a popular research topic for some decades, covering every known specification formalism.  ...

Formalizing and Operationalizing Industrial Standards [chapter]

Dominik Dietrich, Lutz Schröder, Ewaryst Schulz
2011 Lecture Notes in Computer Science  
Specifically, we (i) design a domain specific language for the formalization of industrial standards; (ii) formulate a semantics of this language in terms of a translation into the higher-order specification  ...  We develop a methodology and tools to systematically formalize such standards, in particular their domain specific calculation methods, in order to support the automatic verification of functional properties  ...  Acknowledgements The work reported here was supported by the FormalSafe project conducted by DFKI Bremen and funded by the German Federal Ministry of Education and Research (FKZ 01IW07002).  ...

Using informal and formal techniques for the reverse engineering of C programs

Cheng, Gannod
1996 Proceedings of International Conference on Software Maintenance ICSM-96  
Reverse engineering of program code is the process of constructing a higher level abstraction of an implementation in order to facilitate the understanding of a system that may be in a "legacy" or "geriatric  ...  At the same time, there is a need to preserve the functionality of existing systems as well as reason about the correctness of changed code, each of which is facilitated by the existence of formal specifications  ...  The notation Q f S g R [9] is used to represent a partial correctness model of execution, where, given that a logical condition Q holds, if the execution of program S terminates, then logical condition  ...
