【摘要】 深层网络信息资源获取研究是信息检索领域中一个新的研究课题。本文分析了国内外深层网络资源研究现状,重新界定了深层网络资源范围。分析现存通用搜索引擎的工作原理,引出深层网络形成原因,并根据其形成原因,进一步对深层网络资源进行归类,理顺了深层网络的诸多问题。 在上述研究基础上,本文从微观和宏观两个层次提出了获取深层网络资源解决方案。在微观方面,结合深层网络形成原因及目前的技术发展现状,分别从信息检索过程的参与者:信息提供者、信息服务者和信息检索者三个方面,提出了全面的深层网络资源获取方案;宏观方面,本文认为网络信息资源是人类的智慧结晶,同传统的信息资源一样,它需要得到全方位的组织与保护,政府的参与是必不可少的。文章提出了建立国际、国家、地区三级网络资源保障体系,各级保障体系中分别由政府部门建立专管机构,负责开发、组织网络信息资源。三级机构各司其职,管理好自己的分管区域,相对减少了网络资源管理的压力。这样就可以使庞大的网络纳入政府的宏观控制之中,有效地解决网络资源失控的现状。更多还原

【Abstract】 The deep web is a new subject for research of information retrieval field. This article, on the basis of research results in foreign countries, through analyzing various kinds of deep web research results abroad carefully, has defined the resource range of deep web again. Investigating the deep web further and analyzing it’s forming reason, the author has done more careful argumentation to each kind of origin cause of formation. According to the forming reason of various kinds of deep web, has sorted resources of the deep web in order and carried on a more overall exposition to the deep web. On the foundation of explaining of above-mentioned theories, we have put forward the concrete solution. In the paper, the author has proposed the resource acquisition tactics solution of the deep web from two levels: microcosmic and macroscopic. In microcosmic , through combing the deep web and it’s forming reason, presents technological current situation of the development from the participants of the information retrieval course separately: Information provider , information server and information retrieval person, has put forward the overall micro solution of resource acquisition of deep web; Macroscopical respected, this text thinks the information resources of the network are the human intelligence crystallization, the same as traditional information resources, they need to be omni-directional organized and protected, the government’s participation is essential. The article has proposed setting up world , country , regional tertiary network resource’s security system, The government department should set up and manage the organization of the security systems separately at all levels , is responsible for developing , organizing the information resources of the network. Each performs its own functions in the tertiary organization, In charge of the area of one’s own well, has reduced the pressure of network resource management relatively. In this way, the huge network can be brought into the government’s macro-control, solves the current situation of resources of the network out of control effectively.更多还原
