TL;DR: This approach seems to be of fundamental importance to artificial intelligence (AI) and cognitive sciences, especially in the areas of machine learning, knowledge acquisition, decision analysis, knowledge discovery from databases, expert systems, decision support systems, inductive reasoning, and pattern recognition.
Abstract: Rough set theory, introduced by Zdzislaw Pawlak in the early 1980s [11, 12], is a new mathematical tool to deal with vagueness and uncertainty. This approach seems to be of fundamental importance to artificial intelligence (AI) and cognitive sciences, especially in the areas of machine learning, knowledge acquisition, decision analysis, knowledge discovery from databases, expert systems, decision support systems, inductive reasoning, and pattern recognition.

TL;DR: The theory of rough sets seems a suitable mathematical tool for dealing with problems of vagueness and uncertainty, and is presented as a new approach, based on the rough set theory, for looking to these problems.
Abstract: Vagueness and uncertainty have attracted the attention of philosophers and logicians for many years. Recently, AI researchers contributed essentially to this area of research. Fuzzy set theory and the theory of evidence are seemingly the most appealing topics. On this note we present a new approach, based on the rough set theory, for looking to these problems. The theory of rough sets seems a suitable mathematical tool for dealing with problems of vagueness and uncertainty. This paper is a modified version of the author's lecture titled An inquiry into vagueness and uncertainty, which was delivered at the AI Conference in Wigry (Poland), 1994.

TL;DR: This tutorial paper introduces basic notions of rough set theory and illustrates them with simple examples, and discusses methodologies for analysing data and surveys applications, and presents and introduction to logical, algebraic and topological aspects, major extensions to standard rough sets.
Abstract: A rapid growth of interest in rough set theory 290] and its applications can be lately seen in the number of international workshops, conferences and seminars that are either directly dedicated to rough sets, include the subject in their programs, or simply accept papers that use this approach to solve problems at hand. A large number of high quality papers on various aspects of rough sets and their applications have been published in recent years as a result of this attention. The theory has been followed by the development of several software systems that implement rough set operations. In Section 12 we present a list of software systems based on rough sets. Some of the toolkits, provide advanced graphical environments that support the process of developing and validating rough set classiiers. Rough sets are applied in many domains, Several applications have revealed the need to extend the traditional rough set approach. A special place among various extensions is taken by the approach that replaces indiscernibility relation based on equivalence with a tolerance relation. In view of many generalizations, variants and extensions of rough sets a uniform presentation of the theory and methodology is in place. This tutorial paper is intended to fulllll these needs. It introduces basic notions and illustrates them with simple examples. It discusses methodologies for analysing data and surveys applications. It also presents and introduction to logical, algebraic and topological aspects, major extensions to standard rough sets, and it nally glances at future research.
