Research And Application Of System Of Spam Filtering Based On Semantic Grid

The high speed development of Internet provides convenient and rapid service for people, especially, email has been an indispensable part of the life of people with its fast, low-priced character. However, with the popularization of email, the word "spam" is more and more frequently seen by us. The spam has brought, huge losing to the building and commercial activities of people. Though several spam filters has been published, but we found them more or less exist the problem of semantic absence. Keeping on innovating the information technology (IT), and the technology of spam develops too. When the spam develop to some further degrees, the current spam filter algorithms and the relevant network environment will be difficult to work.For this reason, the paper introduces semantic grid into spam filtering algorithm. Semantic grid not only comes in for the characteristic of resource sharing of grid, but also integrates the advance of intelligent information retrieval of semantic web. Semantic grid provides a piece of new clew for reducing the manual intervention in the spam filtering process, and provides a fresh fundamental platform of high performance for the technology of the spam filtering. Therefore, the research on spam filtering based on semantic grid has a strong theoretical significance and application value.To enhance recall ratio and precision ratio of information retrieval, the paper designs the model of spam filtering based on semantic grid. And on the basis of research, it further exploits the system of semantic grid service model applying for spam filtering which enable the spam filtering more systematization and more integration. Firstly, the paper focuses on design and analysis of the core component of spam filtering system on the basis of study the technology of semantic grid and spam filtering. Also discusses in detail the matching algorithm of the model and definition of the domain ontology. Secondly, it designs overall the system of semantic grid service model applying for spam filtering, and behind the analysis of function of every model, discusses the register service model in the user interface. Finally, the performance of system is checked up by the simulation experiment, and gets the satisfying testing result.
