Research And Design Of A Middleware For Mobile Information Service Platform Of Enterprise

In recent years, the mobile Internet is booming. In order to give full play to theadvantages of the mobile Internet, to speed up the informatization of enterprise and togive a better serve to mobile users, enterprises, governments and other institutions areintended to build their own mobile information service platform. By access to theenterprise mobile information service platform at anytime and anywhere, Mobileusers can get news, the latest announcements, logistics service information and so on.Until now, the main method of building mobile information service platform isdeveloping a mobile version of original platform. The new information platform isbuilt based on the needs analysis of customer and has good user experience. But thereare two drawbacks with this method. The first one, the development of a completelynew system requires a lot of time and money, and the two sets of parallel operation ofinformation services platform increase the routine maintenance work. Second, ingeneral, the mobile information service platform is just a simplified version of thedesktop information service platform, so a lot of work to re-development of a newmobile platform is repetitive work. This will result in the duplication of information,and the waste of network resources.In order to overcome the drawbacks of the traditional way of building mobileinformation service platform, this paper designs a mobile middleware, which canbuild enterprise mobile information service platform intelligently. The middlewarecan extract web information dynamically based on user require, and then push theresult to the mobile device in the specified style. Thus the desktop network resource isadjusted to the mobile device by the middleware. Using the middleware system, wecan build the mobile information service platform just by filling in some of the configuration information about function and style customization. Mobile informationservice platform provides a functional interface to the mobile users. The interfacereceives and passes the mobile request to the middleware system for processing, andthen pushes the result data to the mobile client.Middleware is based on web information extraction, and the core function in theadaptation work of middleware systems is the data processing. The data processing ofmiddleware system is: data source acquisition-data extraction-content integration-style rendering, and the core step is data extraction. Middleware uses a simpleDOM-based data extraction algorithm. Page clustering analysis is used to generatedata extraction template. Data extraction algorithm performs data extraction based onthe extraction rules defined in the extraction template. This article focuses on thedescription of two issues:(1)the contents extraction strategy of the middleware system,including: data processing, data extraction algorithm, as well as solution of SessionSynchronization in the data processing. The Session Synchronization is correctpremise of web page adaptation.(2)the composition of the mobile information serviceplatform constructed by the middleware, and its working principle and otherproblems.The middleware system designed and implemented in this paper can buildmobile information services platform in a rapid speed while making full use of theexisting desktop network platform resources and integrating the existing mobile siteinterface. This can make cross-use of existing network resources and save manpowerand resources to develop a new system, and effectively promote informatization at thesame time.
