SCOPE: A Situation Calculus Ontology of Petri Nets
nets have shown to be quite handy in providing the operational semantics of certain class of Web services, i.e., Web-accessible service programs or devices. For example, in , in order to automatically describe, compose, simulate, and verify the Web service compositions, a Petri net formalism is employed to describe the operational semantics
Programming Languages And Operational Semantics A Concise
Structural operational semantics is a simple, yet powerful mathematical theory for describing the behaviour of programs in an implementation-independent manner. This book provides a self-contained introduction to structural operational semantics, featuring semantic definitions using big-step and small-step semantics of many standard programming

Operational semantics deﬁnes the possible transitions that a piece of syntax can make during its execution Each transition may be
A semantics for multiprocessor systems
A structural operational semantics [Plo81] is defined as a generalization of the rules for CCS. We assume that the following black-box is a model of a multi-processor system which runs a process given n processing elements. There is a 'clock' line which when toggled advances each processing element by one step.

Programming Language Pragmatics Solutions
The book presents a set of tools (a mathematical metalanguage, abstract syntax, operational and denotational semantics) and uses it to explore a comprehensive set of programming language design dimensions, including dynamic semantics (naming, state, control, data), static semantics (types, type reconstruction, polymporphism, effects), and

We express the semantics of Tiny-SHIM in Plotkin s  structural operational style. The state of a process is repre-sented as pair of the form hs;pi, where s represents the state of the local store for each process, i.e., a mapping from a process s variables to values, and p is the statement the process
Testing Semantics for Unbounded Nondeterminism*

Tutorial An introduction to metric semantics: operational and
ication languages. We concentrate on operational semantics, denotational semantics and proofs relating the two. Both in the denition of a denotational semantics and in the proof, metric spaces play a crucial role. In an operational model, the semantics of a language is captured by means of an abstract machine.
A powerdomain for countable non-determinism
the techniques used may be of interest. They comprise a structural operational semantics [Plo2] to specify transitions, redexes (here called actions) to specify potential occurrences (in our case these are also all possible) and residuals to trace potential occurrences through transitions [Bar].

Three phases: Effect of external changes on events and conditions is evaluated, The set of transitions to be made in the current step and right hand sides of assignments are computed, Transitions become effective, variables obtain new values.

An expectation-transformer model for probabilistic temporal logic
probability of moving left or right is bounded below by 1/3 (i.e. it is not known exactly) will return eventually with probability at least 1− √ 5/3. In Sec. 6 we examine the beneﬁts and limitations of using expectations, and discuss how our contributions relate to other approaches, in particular to pCTL and pCTL*.

Alloy is described as a lightweight formal method, since the Alloy Analyzer supports fully automatic analysis of Alloy models. While this analysis is bounded and thus not capable of producing proofs, it does allow for incremental, agile development
Operational semantics of rewriting with priorities
This translation relates the semantics of priority rewriting given in [l] with general techniques to deal with negation in operational semantics and logic programming (for references to logic programming we refer to ). It also explains the negative answer to the third of the open questions.
