【摘要】 因特网是一个巨大的全球性的信息服务中心。传统的媒体受到冲击,逐渐向网络媒体转变,提供网络信息服务的竞争日益激烈。目前的网络新闻服务站点基本上是基于B/S结构的单一的新闻发布系统,而HTML页面技术和HTTP无状态连接协议,没法提供跨媒体的多样化内容的服务,不适于用户按照自己的习惯进行阅读和订购,因而使得Internet新闻服务尚没有摆脱传统的推送服务方式,这已经越来越不满足现在社会发展的需求。虽然目前有一些对此进行研究的成果,但只是比传统的多出一两项服务,并没有满足用户的真正需求。 对于新闻“人性化”的研究方面在国内还属于探索阶段,虽然有一些单位对此进行了一些研究,也取得了一些成果,但是在总体上这些成果都存在各种缺陷。不论系统的完整性还是适用性或是易操作性上及安全性都存在着严重的不足,在实际的生产中难以得到推广应用,至使现在的网络新闻服务工作还停留在传统的发布阶段,不能按照用户自己的意愿进行阅读和订购,不能满足现代社会用户的需要。 本文给出了一种基于Web Services体系架构和采用XML的新闻服务系统模型,讨论了新闻服务体系、新闻注册中心、客户端的工作原理和关键技术,拓展了传统新闻的单一内容发布流程,支持各类多样化内容增值服务、个性化的新闻内容阅读控制和订货服务,并且采用了安全套接字技术(SSL)和用户身份验证技术。而且设计了各端的模型及流程,讨论了相关的关键技术(WSDL,UDDI,SOAP),力求使新闻服务能够满足用户的各种需求,并且操作更加简单,安全性更高,可以让用户及商家更好的交流,满足彼此的要求,使服务更加“人性化”。更多还原

【Abstract】 Internet is a information service centre of enormous globalism. The present network news service website is a simplex system of news release basically based on B/S structure,and HTML page technology and non-state connection HTTP protocol are unable to offer diverse service , so it is not suitable for reader’s reading and ordering according to own habit .Therefore Internet news service can’t meet today’s demands of social development. Though there are some achievements to carry on research at present, the service has not met readers’ real demand.The research of news " anthropomorphize" at home is at the stage of exploration . Though some units have carried on some research and made some achievements, various kinds of defects exist in these achievements on the whole. The integrality or suitability of system or security have serious deficiency, so it is difficult to be popular and be applied in real production.All of these make present network news services still remain at traditional issue stage, and this can’t meet demands of modern social readers.This text provides one news service model that adopts XML and is on the basis of Web Services system,and has discussed the service system of the news and News Registry and the operational principle of customer end.This system supports all kinds of diversified content services and individualized control to read news contents .Moreover,it adopts Secure Socket Layer (SSL) and user’s identity verifies technology. It has designed the model and procedure of every end, and discussed relevant key technologys (WSDL, UDDI, SOAP) to meet various kinds of demand of reader,and it can make operation simpler and has higher securities .This system can make customer and trade company communicate better , meet the mutual demand and enable service " anthropomorphize ".更多还原
