Now ontology has been widely used by Artificial Intelligence as an explicit specification of conceptualization in various areas, such as conceptual modeling, information integration, agent-based system design, and semantic web. In this paper, we introduce rough set theory to Ontology. It extends the uncertainty representation in domain ontology and supports uncertainty reasoning. It is more flexible...
This paper presented an incremental data mining algorithm for mining simplified rules. By using a method of the attribute's number increased progressively to check the superfluity of the decision rules. RIDA makes full use of mined rules to mine decision rules from new instance. This algorithm has a high efficiency with simple calculation compared with classical Rough set mining algorithm. And it...
