基于链接分析的山东高校网站评价研究

Based on the analysis of the Shandong university website links evaluation research

目的通过对高校网站网络信息的计量研究,揭示高校网站的特征、数量关系和内在的普遍规律,使高校在网络信息资源的利用方面发挥更好的作用,充分发挥其办学效益和社会价值。方法以山东省高校网站为研究对象,使用Alexa统计了32所大学网站的人均页面浏览量、日均IP访问量,选用AltaVista检索了网页总数、链接总数和外部链接数作为研究数据,采用两种方式计算网络影响因子,对各元素间的相关性进行了分析,并对山东高校网站的反向链接做了一定的研究。结果山东高校网站的被引率普遍偏低。相关性分析表明,网页总数和网站链接总数有着非常显著的统计学意义。经研究发现,反向链接一定程度上增加了高校网站的点击量。结论传统网络影响因子的计算不能用来评价某个高校的网站情况。山东高校网站内容不够丰富,网站学术交流不多。建议高校重视网站的自身建设,提高网站的内容质量和资源利用率。
