Peter Norvig Inside Google

Google has expanded from searching webpages to searching videos, books, places and even files on your own desktop. This expansion is made possible though Google's understanding and classification of information, facilitated by the application of algorithms in the domains of Machine Learning, Natural Language Processing and Artificial Intelligence. Google has also made use of innovative technologies such as AJAX to improve the accessibility of web interfaces. Some of the products that have come out of the Google Labs experiment are Google Suggest which autocompletes queries as they're typed. Google Sets is another feature where you can specify two or more keywords and generate a whole set depending on the commonality and relationship between the two objects.
