In its clear interdisciplinarity, the Information Science touches various knowledge domains, which are either related to its contents of interest, or related to the forms chosen to represent such contents. This representation, in turn, is characterized not only by its symbols and vocabulary, but mainly by the intelectual context available in its elaboration and which follows all the stages of the associated information life cicle. Therefore, the message (transmitted information) comprehension and the knowledge thus generated are dependent of both, the sender's and the receiver's cognitive apparatus. The study of this process requires a model capable of analyzing the knowledge from a neutral point of view, independent from both the observer and the object of its observation. The Phenomenology proposes to study knowledge from the philosophical point of view, interacting, in this process, with the cognitive sciences, which analyze the involved intelective processes, and with Information Science, which analyzes the registered information.
