David Watt (computer Scientist)
David Anthony Watt (born 5 November 1946) is a British computer scientist. Watt is a professor at the University of Glasgow, Scotland. With Peter Mosses he developed action semantics, a combination of denotational semantics, operational and algebraic semantics. He currently teaches a third year programming language A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually def ...s course, and a postgraduate course on algorithms and data structures. He is recognisable around campus for his more formal attire compared to the department's normally casual dress code.

University Of Glasgow
The University of Glasgow (abbreviated as ''Glas.'' in Post-nominal letters, post-nominals; ) is a Public university, public research university in Glasgow, Scotland. Founded by papal bull in , it is the List of oldest universities in continuous operation, fourth-oldest university in the English-speaking world and one of Scotland's four Ancient universities of Scotland, ancient universities. Along with the universities of University of St Andrews, St Andrews, University of Aberdeen, Aberdeen, and University of Edinburgh, Edinburgh, the university was part of the Scottish Enlightenment during the 18th century. Glasgow is the List of universities in Scotland, second largest university in Scotland by total enrolment and -largest in the United Kingdom. In common with universities of the pre-modern era, Glasgow originally educated students primarily from wealthy backgrounds; however, it became a pioneer in British higher education in the 19th century by also providing for the needs o ...

Scotland
Scotland is a Countries of the United Kingdom, country that is part of the United Kingdom. It contains nearly one-third of the United Kingdom's land area, consisting of the northern part of the island of Great Britain and more than 790 adjacent Islands of Scotland, islands, principally in the archipelagos of the Hebrides and the Northern Isles. To the south-east, Scotland has its Anglo-Scottish border, only land border, which is long and shared with England; the country is surrounded by the Atlantic Ocean to the north and west, the North Sea to the north-east and east, and the Irish Sea to the south. The population in 2022 was 5,439,842. Edinburgh is the capital and Glasgow is the most populous of the cities of Scotland. The Kingdom of Scotland emerged as an independent sovereign state in the 9th century. In 1603, James VI succeeded to the thrones of Kingdom of England, England and Kingdom of Ireland, Ireland, forming a personal union of the Union of the Crowns, three kingdo ...

Peter Mosses
Peter David Mosses (born 1948) is a British computer scientist. Peter Mosses studied mathematics as an undergraduate at Trinity College, Oxford, and went on to undertake a DPhil supervised by Christopher Strachey in the Programming Research Group while at Wolfson College, Oxford in the early 1970s. He was the last student to submit his thesis under Strachey before Strachey's death. In 1978, Mosses published his compiler-compiler, the Semantic Implementation System (SIS), which uses a denotational semantics description of the input language.Peter Mosses, "SIS: A Compiler-Generator System Using Denotational Semantics," Report 78-4-3, Dept. of Computer Science, University of Aarhus, Denmark, June 1978 Mosses has spent most of his career at BRICS in Denmark. He returned to a chair at Swansea University, Wales. His main contribution has been in the area of formal program semantics. In particular, with David Watt he developed action semantics, a combination of denotational, operati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Action Semantics
Action semantics is a framework for the formal specification of semantics of programming languages invented by David Watt and Peter D. Mosses in the 1990s. It is a mixture of denotational, operational and algebraic semantics. Action semantics aim to be pragmatic, and action-semantic descriptions (ASDs) are designed to scale up to handle realistic programming languages. This is aided by the extensibility and modifiability of ASDs. This helps to ensure that extensions and changes do not require too many changes in the description. This is in contrast to the typical case when extending denotational or operational semantics, which may require reformulation of the entire description. The action semantics framework was originally developed at the University of Aarhus and the University of Glasgow The University of Glasgow (abbreviated as ''Glas.'' in Post-nominal letters, post-nominals; ) is a Public university, public research university in Glasgow, Scotland.

Denotational Semantics
In computer science, denotational semantics (initially known as mathematical semantics or Scott–Strachey semantics) is an approach of formalizing the meanings of programming languages by constructing mathematical objects (called ''denotations'') that describe the meanings of Expression (computer science), expressions from the languages. Other approaches providing formal semantics of programming languages include axiomatic semantics and operational semantics. Broadly speaking, denotational semantics is concerned with finding mathematical objects called domain theory, domains that represent what programs do. For example, programs (or program phrases) might be represented by partial functionsDana S.

Operational Semantics
Operational semantics is a category of formal programming language semantics in which certain desired properties of a program, such as correctness, safety or security, are verified by constructing proofs from logical statements about its execution and procedures, rather than by attaching mathematical meanings to its terms (denotational semantics). Operational semantics are classified in two categories: structural operational semantics (or small-step semantics) formally describe how the ''individual steps'' of a computation take place in a computer-based system; by opposition natural semantics (or big-step semantics) describe how the ''overall results'' of the executions are obtained. Other approaches to providing a formal semantics of programming languages include axiomatic semantics and denotational semantics. The operational semantics for a programming language describes how a valid program is interpreted as sequences of computational steps. These sequences then ''are'' the ...

Algebraic Semantics (computer Science)
In computer science, algebraic semantics is a formal approach to programming language theory that uses algebraic methods for defining, specifying, and reasoning about the behavior of programs. It is a form of axiomatic semantics that provides a mathematical framework for analyzing programs through the use of algebraic structures and equational logic. Algebraic semantics represents programs and data types as algebras—mathematical structures consisting of sets equipped with operations that satisfy certain equational laws. This approach enables rigorous formal verification of software by treating program properties as algebraic properties that can be proven through mathematical reasoning. A key advantage of algebraic semantics is its ability to separate the specification of what a program does from how it is implemented, supporting abstraction and modularity in software design. Syntax The syntax of an algebraic specification is formulated in two steps: (1) defining a form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...
