摘要：

In past years ,people were hardly aware of Mapping Knowledge between Environments when dealing with problems,did not consider the ability of their constraint and introduction to handle cognition problem under incomplete information environment. This paper firstly points out the importance of explicit representation on background knowledge,then gives a method that deals with imprecise infor mation aggregation using generalized rough set theory. This process involves representation and acquiring about background knowledge.
