Abstract
This paper presents a user-oriented view of \({\mathcal R}o{\mathcal S}y\), a \({\mathcal R}{\rm ough}\) Knowledge Base \({\mathcal S}\)ystem. The system tackles two problems not fully answered by previous research: the ability to define rough sets in terms of other rough sets and incorporation of domain or expert knowledge. We describe two main components of \({\mathcal R}o{\mathcal S}y\): knowledge base creation and query answering. The former allows the user to create a knowledge base of rough concepts and checks that the definitions do not cause what we will call a model failure. The latter gives the user a possibility to query rough concepts defined in the knowledge base. The features of \({\mathcal R}o{\mathcal S}y\) are described using examples. The system is currently available on a web site for online interactions.
