Interpreted by the system itself or by some other system. Classical view of representation symbols are used to represent things (cave drawings) Computations involve the manipulation of those symbols. Symbols are changed based on a set of rules or syntax which is different from the meaning or semantics. Knowledge is represented locally; at one particular place in the system. Connectionist view of representation - representations are non-symbolic.
