摘要
研究具有复杂结构属性值的信息系统的知识发现问题,探索适合复杂结构数据环境的具有层次结构、立体结构的知识发现方法。在挖掘决策蕴涵和关联规则时,充分考虑属性取值数据的层次结构,提出具有层次结构、立体结构的决策蕴涵和关联规则挖掘方法,讨论原形式背景的决策蕴涵和关联规则与分层形式背景的决策蕴涵和关联规则之间的联系。给出由下层决策蕴涵和关联规则诱导上层决策蕴涵和关联规则的方法,由上层决策蕴涵和关联规则诱导下层决策蕴涵和关联规则的方法。
This paper studies the knowledge discovery problem of information system with complex structure attribute values,and explores the knowledge discovery method with layered structure and three-dimensional structure suitable for complex structure data environment.When we mine the decision implication and the association rules,the layered structure of attribute value data is fully considered,and the mining method of decision implication and association rules with layered structure and three-dimensional structure is proposed,and the relation between decision implication and association rules of original formal background and decision implication and association rules of layered formal background is discussed.It is proposed that the method of inducing the upper level decision implication and association rules from the lower level decision implication and association rules and the method of inducing the lower level decision implication and association rules from the upper level decision implication and association rules.
