百度网页搜索的检索满意度指标进行评估?
首先感谢邀请。简单说下,针对网页检索结果进行评估,主要是围绕精确率和召回率进行,具体如下:
1.相关性:query与结果说的是不是一回事

2.需求强度:抓住主要需求

3.丰富程度:详细全面4.有效性:能否真正满足

5.时效性:新

6.便捷性:找到目标信息要花多少时间和成本

7.权威度:英雄也要问出处说明:这7个维度在不同特征的query下,关注的重点有不一样,不同维度适用的query范围有所不同。

I can’t say much but with my experience through divorce, I had no one until I met hackingsetting50@gmail.com online then I contacted him, surprisingly he helped me hack into my partner's phone and all his social media platforms and i can now access everything and even documented and printed stuffs to show as evidence , now I’m happy with my kids and working for Riches. I hope this helps anyone in need.
