Matching model on numerical uncertain data in possible world
可能世界内数值型不确定数据匹配模型

This paper focused on the matching model of uncertain data.Firstly,classified existing uncertain data into 5 types,and gave normal definitions,proposed the concepts of matching degree and completeness degree to describe their matching effectively and gave the matching model.Then,presented the idea of matching degree and completeness degree between range types as minimum granularity to define the matching rules between others,and defined their detail matching rules.Lastly,cases demonstrated the availability of the matching model.
