Using Domain Knowledge in Initial Stages of KDD: Optimization of Compound Object Processing

Abstract

We present a set of guidelines for improving quality and efficiency in initial steps of the KDD process by utilizing various kinds of domain knowledge. We discuss how such knowledge may be used to the advantage of system developer and what kinds of improvements can be achieved. We focus on systems that incorporate creation and processing of compound data objects within the RDBMS framework. These basic considerations are illustrated with several examples of implemented database solutions.

Fuzzy Set Interpretation of Comparator Networks

“…In our previous research, we investigated a number of applications of compound object comparators going beyond typical classification tasks [6]. We also attempted to provide possibly complete description of how to construct networks of comparators in practice.…”
