About the use of Reference, which of the following statements is NOT correct, according to the text?

Reference is a crucial component within semantics. It can be defined as characterising the relationships between language and the world, in particular, specific entities that are being focused upon. Reference is context-dependent, and ascertaining the meaning of particular referents depends entirely upon who is speaking, whom they are speaking with and in what setting the interaction is taking place.
