【摘要】 随着以高速数据传输为特征的3G网络的建设,手机网络应用技术成为将来移动通讯应用平台关键技术的新趋势,而且目前J2ME平台的硬件环境和市场逐渐变得成熟,J2ME将成为事实上的标准。 J2ME是Java2平台的一个分支,用于消费和嵌入式等资源有限设备上的应用程序开发,尤其适合一些比较复杂、需要智能处理的客户端开发。在无线网络应用领域中采用分布式体系结构,可以实现嵌入式环境中的分布式计算,而J2ME中的Java虚拟机屏蔽了不同机器平台和操作系统的异构性,简化了嵌入式系统的编程。 本文从Java平台无线技术中的J2ME体系架构入手,在无线网络分布式应用研究中,提出了一个基于J2ME与Servlet技术的信息组织与检索的模型,实现了一个实际的模型系统一WTSE(无线翻译搜索引擎),总的来说,WTSE系统模型实现了对J2ME无线网络分布式应用的功能,并将其应用在专业搜索引擎上,并在此基础上参考现有的网络信息组织模式和一些新的信息处理技术,在翻译信息资源的收集、加工和表示上做了一些方法上优化和改进,同时也是一种新的无线翻译应用模式的尝试。 在系统模型的实现中,将其分解成了三个最基本的功能模块:语料库检索模块、检索代理模块和无线终端搜索模块。 语料库检索模块的主要功能是负责将可用于翻译的语料库中的双语信息进行再组织,主要包括对所获取的语料信息建立索引,以便能够快速的找到用户想要的信息;检索代理模块的主要功能是负责响应无线终端的请求服务,并传递该服务与对应的检索模块进行相应请求,同时将获得的检索信息再次处理,反馈给无线终端:无线终端搜索模块的主要功能是负责响应用户的翻译请求,通过J2ME有限资源设备进行联网与检索代理通信,并最终将检索结果显示在无线终端上。 本论文在对Java平台的无线网络技术研究的基础之上,通过对无线翻译搜索引擎的初步实现,为Java无线技术与全文检索技术结合的应用和推广开拓了更广阔的前景。更多还原

【Abstract】 With the construction of the 3G network of high-speed data transfer, cellphone network application technology will become the key technology about mobile telecommunication application platform in the future. Now the J2ME platform hard environment becomes more and more general. And now the J2ME market is more and more living. So the J2ME must be an industry standard.J2ME is a branch of Java 2 platform. It use in the application development of the consumed and embedded connected limited devices, especially being fit of more complex and intelligent client. In the wireless application field developers can implement embedded environment computing with adopting the distributed architecture solution. And the Java visual machine in the J2ME platform overcomes dissimilarity of the different machine platforms and operating systems. It makes the embedded developing easier and easier.This paper is started with introducing the J2ME architecture of wireless technology in the Java platform, in the wireless network distributed application research and has put forward a new model based J2ME and servlet for information organization and retrieve, implement a system-WTSE(Wireless translation search engine), in general WTSE system implement the J2ME wireless network distributed application feature. It is used in special search engine, and on that basis refers to current network information organization mode and some new information processing. For gathering 、 processing and presenting the translation information resource, it has possible ways of optimization and improvement, and also makes attempt about a new mode of wireless translation application.In system implement, it is analyzed three basic function modules: corpus retrieval module、 retrieval proxy module and wireless client search module.The main function of the corpus retrieval module is organizing the bilingual information again in the corpus database for the translation. It mainly includes indexing the gathered bilingual materials for quick searching the information users need.The main function of the retrieval proxy module is in response to the services that the wireless clients request, and transferring it to the corresponding retrieval module to request, then processing gotten retrieval information to return to the wireless client.The main function of the wireless client search module is in response to the services that user request for translations. It connects the network by J2ME Connected Limited Devices and communicates with the retrieval proxy module, finally displays the result on the wireless client.This paper based on the research of wireless network technology in the Java platform, through the elementary realization of wireless translation search engine, opened up broad possibilities for the combine application of Java wireless and full text retrieval technology.更多还原
