Sitnikov, B. D'Cruz, P. E. Sitnikova // Management Information Systems. – 2002. – V. 6. – P. 241-248.http://openarchive.nure.ua/handle/document/5805The logical correlation in knowledge bases and development of a method for knowledge representation and discovery of dependencies between selected data features is discussed. It is pointed out that a knowledge base containing links between information features is represented in the form of logical equations. It is stated that extensible mark-up language (XML) is suitable for the writing of knowledge base in a text file. A subset of XML is developed which allows the data storage in a text file and help in discovering hidden patterns in the data by manipulating XML nodes.enboolean algebracomputational methodsdata processingdata structureshierarchical systemsknowledge acquisitionmathematical transformationspattern recognitionrelational database systemsXMLblood pressurehierarchical structureslogical equationslogical structuresinformation analysisArticle
