面向虚拟企业联盟的多级信息滤波体系设计与实现

1.引言虚拟企业联盟是一个基于广域网络的动态信息集成系统。它的特点是信息系统构成的动态性和可重构性,需要根据用户的需求和企业的成员情况,高效率、高精度地提供相应信息资料。然而,随着企业联盟的不断扩大,用户需求的不断增加,网上查询需求及相应的信息搜索结果成指数地膨胀。在这种情况下,根据用户的需求,在动态的信息搜索结果中,利用信息滤波器准确地提取用户感兴趣的信息,有效地屏蔽信息“噪声”则变得越来越重要。

To Design and Implement the Multi-Level Information Filtering System for the Virtual Enterprise

This paper describes a multi.level filtering information based on the CORBA for the virtual enterprise. The distributed agent and artificial intelligent technology are used to solve the filtering system to adapt to the environment that the user's interest and the resource of information change frequently. This paper raises the function and inference algorithm for the any level of the filtering system. During creating the yellow page of the virtual enterprise,this paper takes the authoritative influence of the leader of an alliance into account . Moreover, the paper shows the better filtering result of the multi-level filtering system in the situation which has a lot of information in a dynamic distributed environment by comparing the filtering performance between other system and this system in the network of the virtual enterprise.
