【摘要】：在介紹網(wǎng)站評(píng)價(jià)與鏈接指標(biāo)的相關(guān)內(nèi)容后,詳細(xì)分析了入鏈數(shù)、網(wǎng)絡(luò)影響因子、Pag-erank算法等鏈接指標(biāo)用于網(wǎng)站評(píng)價(jià)時(shí)存在的缺陷:其一,鏈接指標(biāo)的"第一假設(shè)前提"成立的可能性僅20%左右;其二,商業(yè)搜索引擎(Google、Altavista、Alltheweb等)難以準(zhǔn)確獲取鏈接指標(biāo)值;其三,鏈接處于動(dòng)態(tài)平衡中,鏈接指標(biāo)用于網(wǎng)站評(píng)價(jià)時(shí),將破壞"鏈接平衡態(tài)"。
[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.
