Abstract

This paper presents the RClass system, which was designed as a tool for data validation and the classification of uncertain information. This system uses rough set theory based methods to allow handling uncertain information. Some of proposed classification algorithms also employ fuzzy set theory in order to increase a classification quality. The knowledge base of the RClass system is expressed as a deterministic or nondeterministic decision table with quantitative or qualitative values of attributes, and can be imported from standard databases or text files.
