Posted by Lizzy Van Alstine and Jon Vaver, Quantitative Analysis TeamAdvertisers want to be able to measure the effectiveness of their advertising. Many methods have been used to address this need, but the most rigorous and trusted of these are randomized experiments, which involve randomly assigning experimental units to control and test conditions. At Google, we have found that randomized geo experiments are a powerful approach to measuring the effectiveness of advertising.Many advertising platforms allow advertising to be targeted by geographical...

Posted by John Wilkes, Principal Software EngineerGoogle has a strong interest in promoting high quality systems research, and we believe that providing information about real-life workloads to the academic community can help.In support of this we published a small (7-hour) sample of resource-usage information from a Google production cluster in 2010 (research blog on Google Cluster Data). Approximately a dozen researchers at UC Berkeley, CMU, Brown, NCSU, and elsewhere have made use of it.Recently, we released a larger dataset. It covers a longer...

Posted by Charles DuHadway, YouTube Slam Team, Google Research In an earlier post we talked about the technology behind Instant Mix for Music Beta by Google. Instant Mix uses machine hearing to characterize music attributes such as its timbre, mood and tempo. Today we would like to talk about acoustic and visual analysis -- this time on YouTube. A fundamental part of YouTube's mission is to allow anyone anywhere to showcase their talents -- occasionally...

Posted by Grzegorz Czajkowski, Marián Dvorský, Jerry Zhao, and Michael Conley, Systems InfrastructureAlmost three years ago we announced results of the first ever "petasort" (sorting a petabyte-worth of 100-byte records, following the Sort Benchmark rules). It completed in just over six hours on 4000 computers. Recently we repeated the experiment using 8000 computers. The execution time was 33 minutes, an order of magnitude improvement.Our sorting code is based on MapReduce, which is a key framework for running multiple processes simultaneously...

Posted by Erez Lieberman Aiden and Jean-Baptiste Michel, Visiting Faculty at GoogleFour years ago, we set out to create a research engine that would help people explore our cultural history by statistically analyzing the world’s books. In January 2011, the resulting method, culturomics, was featured on the cover of the journal Science. More importantly, Google implemented and launched a web-based version of our prototype research engine, the Google...

Posted by David Chan and Lizzy Van Alstine, Quantitative Management TeamAdvertisers often wonder whether search ads cannibalize their organic traffic. In other words, if search ads were paused, would clicks on organic results increase, and make up for the loss in paid traffic? Google statisticians recently ran over 400 studies on paused accounts to answer this question.In what we call “Search Ads Pause Studies”, our group of researchers observed organic click volume in the absence of search ads. Then they built a statistical model to predict the...

Posted by Yang Li, Research Scientist We constantly move from one device to another while carrying out everyday tasks. For example, we might find an interesting article on a desktop computer at work, then bring the article with us on a mobile phone during the commute and keep reading it on a laptop or a TV when we get home. Cloud computing and web applications have made it possible to access the same data and applications on different devices and platforms. However, there are not many ways to easily move tasks across devices that are as intuitive...

Posted by Daniel Ford and Josh BatsonThe web is vast and infinite. Its pages link together in a complex network, containing remarkable structures and patterns. Some of the clearest patterns relate to language.Most web pages link to other pages on the same web site, and the few off-site links they have are almost always to other pages in the same language. It's as if each language has its own web which is loosely linked to the webs of other languages. However,...
