177 results about "Semantic difference" patented technology

Semantics is involved with the meaning of words without considering the context whereas pragmatics analyses the meaning in relation to the relevant context. Thus, the key difference between semantics and pragmatics is the fact that semantics is context independent whereas pragmatic is context dependent.
