基于多模式数据传输的个性化信息服务系统设计

Design of personalized information service system based on multimodal data transmission

文中设计一种复合多模式个性化信息服务系统,融合了WLAN、WiFi及Internet等传输模式的优点,提升信息传输效率。信息服务系统功能性模块设计包括用户管理模块、信息检索模块、信息推送模块和数据库模块,网关设计更注重接口的兼容性和信息并行处理能力。在用户网络内容定制方面引入虚拟标签定位算法,结合使用者的偏好和信息内容选择适合的传输模式,节省系统硬件资源的占用。系统测试结果表明,所提系统模块和程序的功能性设计较为完备,系统响应迅速,在高网络负载条件下仍有25%的剩余内存空间。

A composite multi-mode personalized information service system is designed,which integrates the advantages of WLAN,WiFi and the Internet,and strives to improve the efficiency of information transmission. The functional module design of the information service system includes the user management module,information retrieval module,information push module and database module. Its gateway design pays more attention to the compatibility of interface and the ability of information parallel processing. The virtual label positioning algorithm is introduced in the customization of user network content. The suitable transmission mode is selected based on the user′ s preference and information content to save the occupation of the system hardware resources. The system test results show that the functional design of the designed system module and program is relatively complete,its responding speed is fast,and there is still 25% of the remaining memory space under the condition of high network load.
