Also known as: Semantics
Semantic refers to meaning in language, symbols, programs, or data. In AI and natural language processing, semantic analysis focuses on how words, sentences, concepts, or structures relate to real-world meaning and context rather than only surface form.
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 valid strings defined by a specific programming language, showing the computation involved. In such a case that the evaluation would be of syntactically invalid 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
