Over time we’ve improved search by deepening our understanding of queries and web pages. The web isn’t merely words—it’s information about things in the real world, and understanding the relationships between real-world entities can help us deliver relevant information more quickly. Today, we’ve acquired Metaweb, a company that maintains an open database of things in the world. Working together we want to improve search and make the web richer and more meaningful for everyone.
With efforts like rich snippets and the search answers feature, we’re just beginning to apply our understanding of the web to make search better. Type [barack obama birthday] in the search box and see the answer right at the top of the page. Or search for [events in San Jose] and see a list of specific events and dates. We can offer this kind of experience because we understand facts about real people and real events out in the world. But what about [colleges on the west coast with tuition under $30,000] or [actors over 40 who have won at least one oscar]? These are hard questions, and we’ve acquired Metaweb because we believe working together we’ll be able to provide better answers.
In addition to our ideas for search, we’re also excited about the possibilities for Freebase, Metaweb’s free and open database of over 12 million things, including movies, books, TV shows, celebrities, locations, companies and more. Google and Metaweb plan to maintain Freebase as a free and open database for the world. Better yet, we plan to contribute to and further develop Freebase and would be delighted if other web companies use and contribute to the data. We believe that by improving Freebase, it will be a tremendous resource to make the web richer for everyone. And to the extent the web becomes a better place, this is good for webmasters and good for users.
We look forward to working with the talented Metaweb team. We’ll be sure to share details on our progress in the coming months. In the meantime, if you’re interested to learn more about Metaweb’s technology, we encourage you to read their post and do check out the helpful video there.

App Inventor for Android
App Inventor is a new tool in Google Labs that makes it easy for anyone—programmers and non-programmers, professionals and students—to create mobile applications for Android-powered devices. And today, we’re extending invitations to the general public.
For many people, their mobile phone—and access to the Internet—is always within reach. App Inventor for Android gives everyone, regardless of programming experience, the opportunity to control and reshape their communication experience. We’ve observed people take pride in becoming creators of mobile technology and not just consumers of it.
For the past year, we’ve been testing App Inventor in classrooms around the United States, and we’ve found that it opens up the world of computer programming to students in new and powerful ways. David Wolber, professor of computer science at the University of San Francisco and part of the initial pilot program, says “students traditionally intimidated by technology are motivated and excited to program with App Inventor.” One student from Professor Wolber’s class told us: “I used to think that no one could program except CS people. Now, I've made dozens of applications for the Android phone!” Another student, who struggles with dyslexia, was inspired by App Inventor to take more computer science classes and is now learning Python. Check out this video to hear more about App Inventor for Android at University of San Francisco.

Our new search index: Caffeine
Today, we're announcing the completion of a new web indexing system called Caffeine. Caffeine provides 50 percent fresher results for web searches than our last index, and it's the largest collection of web content we've offered. Whether it's a news story, a blog or a forum post, you can now find links to relevant content much sooner after it is published than was possible ever before.
Some background for those of you who don't build search engines for a living like us: when you search Google, you're not searching the live web. Instead you're searching Google's index of the web which, like the list in the back of a book, helps you pinpoint exactly the information you need. (Here's a good explanation of how it all works.)
So why did we build a new search indexing system? Content on the web is blossoming. It's growing not just in size and numbers but with the advent of video, images, news and real-time updates, the average webpage is richer and more complex. In addition, people's expectations for search are higher than they used to be. Searchers want to find the latest relevant content and publishers expect to be found the instant they publish.
To keep up with the evolution of the web and to meet rising user expectations, we've built Caffeine. The image below illustrates how our old indexing system worked compared to Caffeine:
Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.
With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index. That means you can find fresher information than ever before—no matter when or where it was published.
Caffeine lets us index web pages on an enormous scale. In fact, every second Caffeine processes hundreds of thousands of pages in parallel. If this were a pile of paper it would grow three miles taller every second. Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles.
We've built Caffeine with the future in mind. Not only is it fresher, it's a robust foundation that makes it possible for us to build an even faster and comprehensive search engine that scales with the growth of information online, and delivers even more relevant search results to you. So stay tuned, and look for more improvements in the months to come.
