一种近似概念格及其在知识发现中的应用研究
Research on approximate concept lattice and its application in knowledge discovery
摘要
Abstract
Aiming at the problem that the classic concept lattice was limited in incomplete information and it couldn't acquire knowledge of association rules in missing-value context very well,this paper proposed an approximate concept lattice about parameter of tau to solve the problem of knowledge discovery,extracted by association rules with incomplete information.In the background of lower approximate formal context,it built the approximate concept lattice about parameter of tau based on the thought of interval concept lattice.This paper described the construction of approximate concept lattice about parameter of tau and the extraction process of association rules in detail,and acquired the association knowledge rules with higher accuracy and credibility.It could verify the feasibility and effectiveness of that method by case analysis and comparison with two solution strategies of lower and upper approximate concept lattice.关键词
