摘要
Information systems reduction is an important research topic in Information Science; however, in distributed network, how to effectively conduct a dynamic distributed information systems reduction is a problem worthy of study. In this paper, we propose a weighted dynamic information systems reduction method used to conduct the information reduction in a distributed network. In this method, we (1) weigh and combine all the local information reduction results; (2) regard the users' preferences as core attributes; and (3) design recursive algorithms according to the properties. Experimental results show that this method is effective.
