Knowledge Discovery Systems: An Overview

Knowledge Discovery Systems are computer systems that form the backbone of the process of producing explicit or implicit knowledge from analysis of data or from prior knowledge synthesis. Knowledge Discovery in Databases is a promising research area which can bring positive outcomes when properly implementing basic machine learning and discovery methods concerning data storage in relational databases. This paper tries to contribute to a better understanding of the research field by conducting a useful discussion after thoroughly examining decision tree learning algorithms to find implicit and explicit knowledge in databases.
