Définition

La sémantique est l'étude du sens, en philosophie, en linguistique, dans les langages de programmation, en logique formelle et en sémiotique. La sémantique s'intéresse entre autres à la relation entre les signifiants - comme les mots, les phrases, les signes et les symboles - et ce qu'ils représentent dans la réalité.

Semantics (computer science)

In programming language theory, semantics is the field concerned with the rigorous mathematical study of the meaning of programming languages. It does so by evaluating the meaning of syntactically legal strings defined by a specific programming language, showing the computation involved. In such a case that the evaluation would be of syntactically illegal strings, the result would be non-computation. Semantics describes the processes a computer follows when executing a program in that specific language. This can be shown by describing the relationship between the input and output of a program, or an explanation of how the program will execute on a certain platform, hence creating a model of computation.

Formal semantics, for instance, helps to write compilers, better understand what a program is doing and to prove, e.g., that the following if stateme
