TL;DR: A program for approximate classification--based on the rough set concept-- has been developed and aplied for computer-assisted medical diagnosis and results of computation are briefly discussed.
Abstract: This article contains a new concept of approximate analysis of data, based on the idea of a “rough” set. The notion of approximate (rough) description of a set is introduced and investigated. The application to medical data analysis is shown as an example.

TL;DR: This article shows that information about objects provided by a system is given up to an indiscernibility relation determined by the system and hence it is incomplete in a sense, and develops a logic in which properties of knowledge representation systems related to definability can be expressed and proved.
Abstract: In this article we attempt to clarify some aspects of expressive power of knowledge representation systems. We show that information about objects provided by a system is given up to an indiscernibility relation determined by the system and hence it is incomplete in a sense. We discuss the influence of this kind of incompleteness on definability of concepts in terms of knowledge given by a system. We consider indiscernibility relations as a tool for representing expressive power of systems, and develop a logic in which properties of knowledge representation systems related to definability can be expressed and proved. We present a complete set of axioms and inference rules for the logic.
