Faults Of Human Review 
By: Aaron Wall 2007-05-31 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.
