All mathematical theories of Information in the late fourties suggested rival concepts of information; furthermore the notion of seemed to have been left out Shannon's analysis of the amount of Information in a signal disclaimed explicity any concern with its meaning and had been qualified as inadequate by the Semanticists. Bar—Hillel and Carnap, 1952, suggested two possible measures of the Information content of statements in an artificial language system. Schreider, 1965. states that in several situations the receiver's ability to understand the communication is the most Important characteristic of the process. Goffman expanded Shannon's theory in his General Theory of Communication, where there are 3 large phenomena to be considered — Information generation, transmission and use. If we consider the effect of Relevance on the receiver and explore further its implications me might be closer to a better and unified theory of information than we are with the introduction of meaning — a point still in discussion among Semanticists.
