引擎人工二次检查的缺陷
苏力凡·丹尼最近写了篇帖子，高调的指出了搜索引擎在人工第二次检验时的缺陷。
迈尔·提姆告诉我们对搜索引擎的提问的关联会极速的改变。昨天我在google访问曼波·巫帝，google的工程副主席时，针对我问到的人工纠正的搜索结果时他也做出了相似的言论。他给我举了一个例子，来说明google的人工质量纠正系统是怎样工作的（google雇佣了一批人来对搜索结果进行二次检验，以此他们能够更好的调整爬虫）：当人工检验对“汽车”的搜索结果进行降级时，电影《汽车》的信息却开始涌现。在人工检验没有发现电影的出现时，爬虫已经把关键词的重要性提放在电影上了。
众所周知，各大搜索引擎都在使用人工检验，但即使引用了外部资源的检验，人工检验还是有极限的。

The Faults of Human Review
Danny Sullivan's recently made a post highlighting the downside of human review for search engines:
[Tim] Mayer reminded that what's relevant for a query can often change over time. Google's Udi Manber, vice president of engineering, made similar remarks when I spoke with him about human-crafted results when I was visiting at Google yesterday.
One example he pointed out was how Google's human quality reviewers -- people that Google pays to provide a human double-check on the quality of its results, so they can then better tune the search algorithm -- started to downgrade results for [cars] when information about the movie Cars started turning up. The algorithm had picked up that the movie was important to that term before some of the human reviewers were aware of it.

Obviously human review is used at all major search engines, but even when outsourcing reviews humans have limits just like with producing content.
