Method and tool for data mining in automatic decision making systems
First Claim
1. A method for automated decision-making comprising the steps of:
- constructing a series of interconnection cells and using values obtained thereby as decision makers, said construction comprising;
a) modeling of relations between a plurality of objects in a system, each object having at least one outcome, each object being subjected to at least one influential factor affecting said at least one outcome and building said modeled relations as interconnections between said interconnection cells;
b) carrying out computerized data mining in datasets associated with said modeled relations between said at least one outcome and said at least one influential factor of at least one said object, and constraining said data mining to relations modeled by said interconnections;
c) building a quantitative model to predict a score for said at least one outcome, by attributing values from said data mining to said relations; and
d) making an output decision for said system according to said score of said at least one outcome of said at least one object.

Abstract
In an automatic decision-making system, a method and a tool for the reduction of the dimension of data mining, which is automatically coupled to an empirical predictor of the system. The method includes a qualitative modeling of the interrelations between various objects whose attributes are relevant to a score made by the predictor according to which decisions are made, wherein this relevancy is determined by an input of a domain expert to the problem in hand. The model is called a Knowledge-Tree and its conclusions are represented by a graphical symbolization called the Knowledge-Tree map. Data mining, which follows the construction of the Knowledge-Tree map regards only datasets which are associated with logical and validated branches of the knowledge tree. Because the expert input which reduces the dimension of data mining was completed prior to data mining, interception by human reasoning is not needed after data mining and the decision making process can proceed automatically.
