Chapter 10 Case Study: Yahoo! Answers Community Content Moderation
F. Randall "Randy" Farmer has been creating online community systems for over 30 years, and has co-invented many of the basic structures for both virtual worlds and social software. His accomplishments include numerous industry firsts (such as the first virtual world, the first avatars, and the first online marketplace). Randy worked as the community strategic analyst for Yahoo!, advising Yahoo properties on construction of their online communities. Randy was the principal designer of Yahoo's global reputation platform and the reputation models that were deployed on it.
Bryce Glass is a principal interaction designer for Manta Media, Inc. Over the past 13 years, he's worked on social and community products for some of the web's best-known brands (Netscape, America Online and Yahoo!).
The animal on the cover of Building Web Reputation Systems is a Pionus parrot. The Pionus genus includes eight different species. These medium-size birds are native to Mexico, Central America, and South America, and are characterized by a stocky body, a naked eye ring, and a prominent beak. In addition, they have short, square tails with red coverts (undersides), and as such, have also been known as red-vented parrots.One unique characteristic of the Pionus parrot is its stress response. When threatened or intimidated, the birds exhibit one of three different behaviors. The most severe is thrashing; if something frightens them, such as their cage being struck or jarred while they are asleep, the parrot will thrash around until it is calmed. The second response is total stillness; at bird shows, a Pionus may be observed sitting completely motionless while other species scream or demonstrate more common stress signals. Finally, when frightened or excited, the Pionus emits a very distinct wheezing or snorting sound, almost as though it is having an asthma attack.
Comments about O'Reilly Media Building Web Reputation Systems:
This is a really interesting book about allowing users to provide feedback/ratings on your content or services, including common algorithms for calculating those ratings, the value of each user's ratings, and how to manage this information. I found this very enlightening, as many of the ideas discussed in this book hadn't initially occurred to me.
Perhaps the most useful material, in my opinion, was the discussion around different reputation models. Included in the discussion were the models used by eBay, Yahoo!, Slashdot, and others. Also very valuable were the algorithms for tabulating ratings and reputation so that performance is not impacted.
I found the information in this book invaluable in building online rating systems. If you're working on such a project, I'd highly recommend checking out this book.
Bottom Line Yes, I would recommend this to a friend
