SELECTION OF BASIC INFORMATION FOR FORMATION OF THE DB BY WAY OF EXAMPLE OF MULTICOMPONENT SYSTEM NACL–KCL–MGCL2•H2O

Abstract

In article is offered the way of a search of the facts like unusual data (these raising doubts) by forming databases from several sources. As criterion for search of such data it is offered to use a method of pattern recognition – decision rule. By using two and more decision rules there are crossings at which objects which can’t be classified correctly by means of such decisive rules are formed. As an example of a search of the data like unusual data application of this method is shown in the analysis of the data of heterogeneous balance in NaCl–KCl–MgCl H2O system published in 12 various sources for the different periods of time. Accuracy of classification has made 92–98%.
