This fascinating book demonstrates how you can build web applications to mine <br />
the enormous amount of data created by people on the Internet. With the <br />
sophisticated algorithms in this book, you can write smart programs to access <br />
interesting datasets from other web sites, collect data from users of your own <br />
applications, and analyze and understand the data once you've found it.<br />
Full Description<br />
Want to tap the power behind search rankings, product recommendations, social <br />
bookmarking, and online matchmaking? This fascinating book demonstrates how you <br />
can build Web 2.0 applications to mine the enormous amount of data created by <br />
people on the Internet. With the sophisticated algorithms in this book, you can <br />
write smart programs to access interesting datasets from other web sites, <br />
collect data from users of your own applications, and analyze and understand the <br />
data once you've found it.<br />
<br />
Programming Collective Intelligence takes you into the world of machine learning <br />
and statistics, and explains how to draw conclusions about user experience, <br />
marketing, personal tastes, and human behavior in general -- all from <br />
information that you and others collect every day. Each algorithm is described <br />
clearly and concisely with code that can immediately be used on your web site, <br />
blog, Wiki, or specialized application. This book explains:<br />
<br />
* Collaborative filtering techniques that enable online retailers to <br />
recommend products or media<br />
* Methods of clustering to detect groups of similar items in a large dataset<br />
* Search engine features -- crawlers, indexers, query engines, and the <br />
PageRank algorithm<br />
* Optimization algorithms that search millions of possible solutions to a <br />
problem and choose the best one<br />
* Bayesian filtering, used in spam filters for classifying documents based <br />
on word types and other features<br />
* Using decision trees not only to make predictions, but to model the way <br />
decisions are made<br />
* Predicting numerical values rather than classifications to build price <br />
models<br />
* Support vector machines to match people in online dating sites<br />
* Non-negative matrix factorization to find the independent features in a <br />
dataset<br />
* Evolving intelligence for problem solving -- how a computer develops its <br />
skill by improving its own code the more it plays a game<br />
<br />
Each chapter includes exercises for extending the algorithms to make them more <br />
powerful. Go beyond simple database-backed applications and put the wealth of <br />
Internet data to work for you.<br />
