Scientific paradigm of informatics: Classification of domain objects

A description is given of the three top levels of classification of domain's objects of informatics which is positioned as an integral part of the system of scientific knowledge that covers a wide range of information and computer sciences. With such positioning, the boundaries of the domain expand significantly and largely correspond to the concept of polyadic computing by Paul Rosenbloom. All entities of informatics in the proposed scientific paradigm are divided into two global classes: objects and their transformations. For each class, in the process of creating the paradigm, its own classification is constructed. The paradigm's creation began with the formation of these classifications. The paper discusses the three top levels of classification of domain's objects of informatics. The basis for constructing the first (the highest) level is the division of the domain of informatics into the media: mental, sensory, digital, and a number of other media. The basis for constructing the second level of objects' classification is the division of sensory perceived objects of informatics into data and sign information which is the outcome of transformation of human cognitive structures into a sign form. The basis for constructing the third level of classification of objects is the typology of sign systems by A. Solomonick. The aim of the paper is to describe the approach to constructing the three top levels of classification of domain's objects of informatics and to compare it with the previously used approaches to describing its subject domain. Also, based on the proposed approach, the answers to those questions of Thomas Kuhn about the basic entities of the subject domain which should contain the paradigm of any science, not just informatics, are partly formulated.
