Research On Muti-Agent Cooperation Mechanism In Web Data Mining System

With the explosive growth of data on the Web, much of these important information among the massive data often can not be mined and utilized fully.Web data mining technology brings hope to solve this problem. But traditional web data mining systems have these problems of low efficienty, aggravating network congestion, constraining network services and development and so on. To overcome these drawbacks, it is necessary to find a kind of new data mining mechanism.Intelligent Agent is a focus at present.Multi-agent cooperation not only enhances the ability of multi-Agent system to solve problems,but also makes multi-Agent system more flexible.Agent technology introduced to solve the current problems of web data mining would be a good way. Based on the research of basic theories of Agent system , through designing tasks decomposition method, tasks dispatch and tasks allocation among multi-Agent system, the model of multi-Agent cooperation and a model of mobile Agent used in web data mining are designed. The key technology of plan,conflict and communication mechanism is solved. Through using the Aglet of mobile Agent platform the system is designed.Mobile Agent technology is applied to web data mining system, which can save a lot of network bandwidth.And mobile Agents run on server without a continuous connection to the client which is more flexible. The cooperation mechanism of multi-Agent system is used in this system ,which can overcome limitations of resources, space-time distribution and function in the single-Agent system so that it can achieve the system objectives better.
