【摘要】 随着计算机和网络技术的飞速发展,信息化成为各行各业的工作重点。国家和政府对国防科技信息化重视程度不断加大,对国防科技信息化建设投入大量资金,作为国防科技信息化的窗口和平台,科技信息网站也越来越多。但是这些国防科技信息服务网站是否达到了预期的建设目标,是否发挥了应有的作用,都是值得研究的问题。网站的影响力是反映网站被利用程度的一个重要标志。一个网站的影响力越大,网站的资源就越容易被发现和利用,可以通过评价相关网站的影响力来揭示网站被利用的情况。本文回顾了网络计量学的理论、研究方法和研究工具。总结出网站影响力的定义。然后对网站影响力评估的方法进行了总结,归纳出当前研究中用于评估网站影响力的指标。对网络计量学常用的研究工具,如搜索引擎、链接分析工具、网站复制工具的使用方法、优缺点进行了研究和对比。对每个指标的含义、用途、获取方式进行了研究。对科技信息服务网站的相关概念进行了研究,对于科技信息与科技信息资源、科技信息服务网站、科技信息的影响力以及科技信息网站的影响力进行了辨析,并确定了用于评估科技信息服务网站影响力的相关指标。在此基础上,构建了科技信息服务网站影响力评估模型。选择典型的国防科技信息服务网站进行了实证研究,得出了这些国防科技信息服务网站影响力评估的结果。对主要指标的分析表明出访问人数与入链网页数、网站的服务和功能与网站影响力、网站提供信息的多样化程度与网站影响力存在正相关性,这些国防科技信息服务网站表现出较明显的权力影响力特征。在对国防科技信息服务网站影响力评估结果分析的基础上,提出相关政策支持、搜索引擎优化、适度宣传推广等策略来提升国防科技信息服务网站的影响力。更多还原

【Abstract】 With the rapid development of computer and network technology, informa-tization is undertaken in all walks of life. The state and country has invested a huge amount of money to the informatization of defense-related science and technology.More and more websites that provide information technology services are being b-uilt with the the informatization of defense-related science and technology.So,whether these websites can be found inso many websites,whether these websites are used,is worthy to research.The power of influnce of websites stands for the degree that they are being used. The more powerful the influence is, the resources that the websites provide are easier to be found and used.Webometrics is the study of the quantitative aspects of the construction and use of information resources, structures and technologies on the Web drawing on bibliometric and informetric approaches.The power of influnce of websites can be measured by means that webometrics provides.First the theory,means,tools of webometrics are researched in this article,and the po wer of influnce of websites is defined.Then the indexes tomeasure the power of in flunce of websites are researched,includes the meaning of the indexes,the usage of them, and how to get them.Then the releated definations of websites providing information technology services are discriminated, and the indexes to measue the power of defense-related science a nd technology websites are selected.After that,a model to measure the power of influence of websites that provide infor mation technology services is built via AHP.And the power of influence of a set of defense-related science and technology websites is measured.Then an analise of t he result is given.At last, some suggestions to enhance the power of influence of defense-related scie nce and technology websites are given.更多还原
