基于模糊三支区间集半概念知识提取方法研究
Research on Knowledge Extraction Method Based on Fuzzy Three-way Interval-set Semiconcept
摘要
Abstract
In order to solve the problem of only considering the attribute interval-set to the object interval-set,the classical semiconcept theory was introduced into the fuzzy three-way interval-set.For a fuzzy for-mal context,attribute-induced fuzzy interval-set semioperator was defined,which was used to obtain fuzzy AE-interval-set semiconcept.And furthermore,a partial order relation and the correspondent lattice struc-ture were discussed.As a result,an algorithm of searching out all of fuzzy AE-interval-set semiconcepts in a formal context was acquired.Dually,the definition and the correspondent lattice structure of fuzzy OE-interval-set semiconcept were obtained.Meanwhile,an algorithm of searching all of fuzzy OE-inter-val-set semiconcepts was got.The obtained results were helpful to expand the applications of theories of formal concept lattice and interval-set,and also useful for knowledge extraction.关键词
