摘要
本文将网络信息的生命周期定义为网络信息从产生到失去效用价值所经历的各个阶段和整个过程,选取中文学术资源网、外文学术资源网、论坛网站、新闻网站和大型网站为研究对象,采取引文分析法和链接分析法,对网络信息的生命周期现象进行了观察和记录,通过对数据的处理和分析,揭示了一般意义上网络信息生命周期的基本规律和特性。
In this paper, the lifecycle of network information is defined as the various phases and entire process experienced by network information from its birth to the end of its utility value. Selecting the Chinese aca- demic resources network, foreign academic resources network, forum Websites, news Websites and large Websites as the objects of research, this paper observes and records the phenomenon of the lifecycle of network information by the use of the citation analysis and link analysis methods. By processing and analyzing the data, the paper reveals the basic rules and characteristics of the lifecycle of network information in a general sense.
