Design And Implementation Of Spam Message Monitor Strategy Optimization System

With the popularity of mobile phones,mobile phone short message service brings convenient to people's information communication,at the same time,also becomes criminals' tool to seek benefits and spread rumours etc.In recent years,spam messages' flood has seriously affected people's daily life,and the management of spam messages becomes operators' urgent and important problem.As spam message monitor strategy is the main way of filtering spam messages in communication network monitor system,how to effectively optimize existed strategies to make the optimized strategies work better,is significant in management of spam messages,at the same time,also is the main function of the system this paper introduced has done.This paper is derived from an actual project of the domestic operator,I am responsible for the design and implement of the spam message monitor strategy optimization system,the system is committed to reduce labor's workload and cost of optimize strategy and guarantee the effect of optimization,from improving the precision of monitor message and expanding the scope of the monitoring intelligently to implement the optimization of monitor strategy.Through early researching the design of relevant system,combined with the demands of this topic develop the system's design principle,and using a layered system architecture bottom-up from data layer,data access layer,business logic layer,model layer,control layer and presentation layer 6 level to design the whole system.To solve the problem of current the candidate word of strategy optimization mainly rely on artificial select,its accuracy is not guaranteed and cannot effectively monitor massive spam messages,propose spam message clustering algorithm and candidate word of strategy optimization generation algorithm,design and implement the two algorithms and analyze the results of experiment.Spam message monitor strategy optimization system implement strategy evaluation,strategy precision optimization,similar SMS missing optimization and ordinary SMS missing optimization four functions,can effectively optimize strategy.Strategy evaluation including SMS file processing,strategy file processing and strategy evaluation,complete the initialization function;Strategy precision optimization including strategy index calculation,strategy path splitting and strategy optimization,enables strategy to improve monitor accuracy;Similar SMS missing optimization including spam message clustering,missing spam message partial matching strategy generation and strategy optimization,enables strategy to expand monitor scope.Ordinary SMS missing optimization including missing messages generation and strategy optimization,enables whole strategies to monitor all spam messages.At present,the system has been completed and successfully put into use in operator headquarter,and several provincial operators through the country are deployed the system.
