摘要
Abstract
In the real world, some objects have more general meaning than the others, the degrees of
similarity of two objects may not be symmetric. The relation of similarity between two objects may nei
ther necessarily be symmetric nor transitive, we represent it by a weak similarity relation. This paper
puts forward the asymmetric redundancy of tuples in a fuzzy relational database dealing with weak fuzzy
similarity relations, the concept of asymmetric redundancy of tuples is the expansion of the concept of
redundancy in the fuzzy relational database. It is used to delete some redundancy information, and repre
sent more accurate information.关键词
