Information flow and levels of abstraction －an elucidation of foundational problems in philosophy of information

Abstract

    Information flow has been extensively discussed. There are various kinds of information flow in the environment. By using them, we produce and use information. In this paper, we first present the fundamental idea of J. Barwise and J. Seligman’s information flow. On the other hand, the area of philosophy of information is also remarkably developed. In particular, we focus on the method of Level of Abstraction (LoA) introduced by L. Floridi. The method of LoA allows us to extract suitable information from some systems. Combining the concepts of information flow and LoA, we can significantly understand these concepts.
