A deep, insightful, and well-presented treatment of on-line reputation models,
Amazon Verified Purchase(What's this?)
This review is from: Building Web Reputation Systems (Paperback)I'm researching different models to use for our corporate collaboration platform and I'm looking to implement a social recognition/reputation framework. Our framework needs to make sense for users and content in many different businesses and support functions. It's one thing to rate things on Amazon and Netflix and another to deploy a system inside an enterprise. (I'd also researched peter Reiser's "Community Equity" - [...])
This excellent book proved *extremely* useful. It dissects the different popular models - Amazon, eBay, Yahoo, Digg - as well as many others I was not familiar with. It analyzed each and clearly highlighted the pros and cons of each; how different models can be used (and abused) to meet different business objectives. Priceless.
More than a dry analysis, the book is filled with interesting (to me!) insights on the potential pitfalls of each model. I was often surprised at how things I took for granted had some hidden biases or other traps. The sections on the issues with leaderboards, for example, were clear and practical.
My only advice when reading is to skim the initial chapter on the "graphical language" for reputation models. It seemed unnecessary and too abstract. It almost put me off from reading the rest of the book but I needed help. And I'm really glad I continued. The remaining chapters got more and more engaging. The final case study on preventing abuse in Yahoo Answers reads like a page-turner. (Really!)
If you are building any kind of application with ratings or some kind of recognition/social capital/reputation for users, then read this book. It will help you avoid the mistakes made by others before you (you'll never forget the story of The Dollhouse Mafia). And it will help you meet your business objectives for including ratings and reputation in the first place.
