Abstract: In his notes on semiotics, C.S. Peirce probed the concept of information, an essential term in contemporary communication theories. According to Peirce, information, the quantity of interpretants, becomes intertwined with the sign’s width and depth to form a dynamic triadic relation. Correspondingly, the static and dualistic structure of the sign’s meaning becomes dynamic and triadic, determined by the interpreter’s competence. Inspired by these thoughts about information, Peirce pondered both the trichotomy of signs and the nature of “indeterminacy” in information production in relation to cognitive processes. Hence, his theories on information laid the foundation for the bidirectional communication pattern in the semiotics of communication, and continue to inspire current studies in cognitive communication.
Key words: Information, C.S. Peirce, semiotics of communication, structure of meaning, cognitive patterns, bidirectional communication
