Amazon Recommendation Engine: Single Cylinder at Best
By Josh Simons on Mar 22, 2008
I just received an email from Amazon, recommending a book, The TreasureHunter's Gem & Mineral Guides To The U.S.A.: Where & How to Dig, Pan And Mine Your Own Gems & Minerals: Northeast States. Admittedly, they did a good job of predicting this title might be attractive to me. However, the single review on the Amazon site gives the book only a single star and provides some fairly damning evidence that the book is, in fact, totally useless. Hardly an incentive to make a purchase...or to trust future Amazon recommendations.
While I do understand that opinions vary widely across many Amazon reviews and they should not be the final arbiters in a buy/no-buy decision, I would think the Amazon recommendation engine would make some attempt to factor the reviews into their ratings. Or, at the very least, the marketing email should include the overall reviewer rating in the advertisement.
