Thedistributed agent and artificial intelligent technology are used to solve the filtering system to adapt to the environmentthat the user's interest and the resource of information change frequently. This paper raises the function and inferencealgorithm for the any level of the filtering system. During creating the yellow page of the virtual enterprise,this papertakes the authoritative influence of the leader of an alliance into account . Moreover, the paper shows the better filter-ing result of the multi-level filtering system in the situation which has a lot of information in a dynamic distributed en-vironment by comparing the filtering performance between other system and this system in the network of the virtualenterprise.展开更多

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