Shannon assumes communication initiated by
SELECTING a desired message from a set of
possible messages
Then, information is the amount of uncertainty in the
SOURCE (not the message).  This the amount of entropy
(randomness).  “Information is a measure of one’s freedom
of choices when one selects a message.” P. 9
Weaver discussed three levels of communication problem
Accuracy of transmission (technical problem)
Degree of meaning (semantic problem)
Effect of transmission (effectiveness problem)
Do not confuse information with meaning!!
