A Preference Utility-Based Approach for Qualitative Knowledge Discovery

Abstract

This chapter gives a short description of a prototype Decision Support System (DSS), which assesses the value and/or utility functions of the individual user. This DSS allows de-facto training of the computer in the same preferences as that of the individual user without the need of additional participant or mediator in the process of utility evaluation. It is mathematically backed up by the methods described in the preceding chapters. The presented methodology and mathematical procedures allow for the creation of such individually oriented DSS for analytic representation of the preferences as objective function based on direct comparisons or on the gambling approach. Such systems may be autonomous or parts of a larger information decision support system.
