The Best Web Site On The Internet

Larry Page and Sergey Brin met at Stanford University in the spring of 1995 as a computer science graduate students, and quickly became close friends.

Ten years later, they were each worth more than $ 10 billion and have shaped the entire way we use the Internet. How do they do? The problem with the Internet Page and Brin were always together. On campus, which became known as LarryandSergey. The banter between the two knows no bounds. Being difficult and debating each and anyone else who might aspire to a good argument.

They talked endlessly about computers, philosophy, and anything else popper in their minds. Once argued loudly about whether it is possible to construct a building-size screen beans.

Under the desktop Page, who built a computer rack of Legos. The others in his office is practically impossible to get any work done without tuning out. Rajeev Motwani, Sergey's advisor, the relationship between intellectual growth seen Page and Brin.

"Both were brilliant, some of the most intelligent people I have met," Motwani said. "But they were brilliant in different ways.

" Brin was practical, a problem solver, an engineer. If something worked, it worked. Page, meanwhile, has been a deep thinker. He wanted to know why things worked. Brin has been working closely with Motwani on "data mining," finding ways to extract information from the large mountain of data. Data mining can be used by retailers, for example, to see what combinations of items customers buy in the stores so they can better organize the products. Brin and Motwani experimented with applying the same techniques to new, unorganized Internet. In the mid-1990s, the Web was a virtual Wild West, unregulated, uninhibited, and rebellious. Millions of people in identifying and began using e-mail, but serious researchers grew amid the frustration of countless Web sites. The first efforts on "search" program to help users find information on the Internet fell short.

Jerry Yang and David Filo, another pair of Stanford graduate students, tried a new approach to the search. Rather than relying on technology alone, which employed a team of editors that certain Web sites for a directory sorted alphabetically. They called their company Yahoo! Although its simplified approach to find valuable information, you can not keep up with the rapid growth of the Web. Brin and Motwani tried Yahoo! and other directories and search engines, but did not get the job done.

Instead, a simple search yields hundreds or thousands of results in no apparent order. It took them hours to sift through the pages to find what they seek. Brin and Motwani became convinced that he had to be a better way to search the Internet. At the same time, Page began hunting around the Web using a new search engine called AltaVista. Although he returned little better and faster than the results from other search engines, Page noticed something else entirely. In addition to a list of Web sites, AltaVista search results include seemingly useless information about something called "links".

Computer users see a link-a word or phrase you can click on this link for more information and to be taken immediately to another web page. Instead of focusing on the main AltaVista search results, Page wanted to analyze the links and see how that could be used more. However, to test any of their theories, Page would have a large database.

Always ambitious, who did some quick calculations, and then told his adviser was afraid of Stanford was going to download the entire World Wide Web on your desktop. On its face, the idea seemed absurd Page.

He even stated that the discharge of the Web can be done fairly easily and quickly. While others scoffed, Page was very seriously, and on a mission to capture as much for its investigation. Larry's Big Idea As used in 1996, Brin and Page were joined to download and analyze Web links. It took longer to get the data that Page had planned, but he desperately wanted to see through. His drive to discover the importance of these ties also attracted the attention of Brin adviser, Motwani, as it held the promise of improving the investigation of the cloth. Brin was prepared for the project by the opportunity to work with Page and for his own interest in the mining giant amounts of random data.

From his research, Page developed a theory: counting the number of links pointing to a Web site is a way of ranking the popularity of the site. While the popularity and quality do not always go together, he and Brin has grown both in homes valued up to academic research published in academic journals with citations (references to other works). Links, in a sense, Page reminded of appointments.

The scientists cite the publication of the documents of his work was based on, and these appointments are a useful way to monitor credit and influence in academic and research communities. A large number of citations in scientific literature, he said, "means that their work was important, because other people thought it was worth mentioning."
