发布时间：2019-07-21 07:07
【摘要】：在介绍网站评价与链接指标的相关内容后,详细分析了入链数、网络影响因子、Pag-erank算法等链接指标用于网站评价时存在的缺陷:其一,链接指标的"第一假设前提"成立的可能性仅20%左右;其二,商业搜索引擎(Google、Altavista、Alltheweb等)难以准确获取链接指标值;其三,链接处于动态平衡中,链接指标用于网站评价时,将破坏"链接平衡态"。
[Abstract]:After introducing the related contents of website evaluation and link index, this paper analyzes in detail the defects of link index such as the number of links, network influence factors and Pag-erank algorithm when used in website evaluation: first, the possibility of establishing the "first hypothesis" of link index is only about 20%; second, it is difficult for commercial search engines (Google,Altavista,Alltheweb, etc.) to obtain the link index value accurately. Third, the link is in dynamic equilibrium, and when the link index is used for website evaluation, it will destroy the link equilibrium.
