Abstract

In this article, we discuss how previously discovered knowledge can be used in future knowledge-discovery processes. This is an important topic as in real-life environments data collected in databases change, and patterns mined in the past may no longer be valid. In such situations, the users always want to know what data and patterns have changed and how they have changed. The ability to mine interesting knowledge and/or changes based on previously discovered knowledge is crucial. This article reviews some main techniques related to this topic.
