O'Reilly Media. Very Good. 7 x 0.9 x 9.19 inches. Paperback. 2007. 362 pages. <br>Want to tap the power behind search rankings, prod uct recommendations, social bookmarking, and online matchmaking? This fascinating book demonstrates how you can build Web 2.0 appl ications to mine the enormous amount of data created by people on the Internet. With the sophisticated algorithms in this book, yo u can write smart programs to access interesting datasets from ot her web sites, collect data from users of your own applications, and analyze and understand the data once you've found it. Program ming Collective Intelligence takes you into the world of machine learning and statistics, and explains how to draw conclusions abo ut user experience, marketing, personal tastes, and human behavio r in general--all from information that you and others collect ev ery day. Each algorithm is described clearly and concisely with c ode that can immediately be used on your web site, blog, Wiki, or specialized application. This book explains: Collaborative filt ering techniques that enable online retailers to recommend produc ts or media Methods of clustering to detect groups of similar i tems in a large dataset Search engine features--crawlers, index ers, query engines, and the PageRank algorithm Optimization alg orithms that search millions of possible solutions to a problem a nd choose the best one Bayesian filtering, used in spam filters for classifying documents based on word types and other features Using decision trees not only to make predictions, but to mode l the way decisions are made Predicting numerical values rather than classifications to build price models Support vector mach ines to match people in online dating sites Non-negative matrix factorization to find the independent features in adataset Evo lving intelligence for problem solving--how a computer develops i ts skill by improving its own code the more it plays a game Each chapter includes exercises for extending the algorithms to make t hem more powerful. Go beyond simple database-backed applications and put the wealth of Internet data to work for you. Bravo! I c annot think of a better way for a developer to first learn these algorithms and methods, nor can I think of a better way for me (a n old AI dog) to reinvigorate my knowledge of the details. -- Da n Russell, Google Toby's book does a great job of breaking down the complex subject matter of machine-learning algorithms into p ractical, easy-to-understand examples that can be directly applie d to analysis of social interaction across the Web today. If I ha d this book two years ago, it would have saved precious time goin g down some fruitless paths. -- Tim Wolters, CTO, Collective Int ellect Editorial Reviews About the Author Toby Segaran is a sof tware developer and manager at Genstruct, a computational systems biology company.
