Skinner , Page and Brin reasoned that low cost pigeon clusters PCs could be used to compute the relative value of web pages faster than human editors or machine-based algorithms. And while Google has dozens of engineers working to improve every aspect of our service on a daily basis, PigeonRank continues to provide the basis for all of our web search tools. Why Googles patented PigeonRank works so well PigeonRanks success relies primarily on the superior trainability of the domestic pigeon Columba livia and its unique capacity to recognize objects regardless of spatial orientation . The common gray pigeon can easily distinguish among items displaying only the minutest differences, an ability that enables it to select relevant web sites from among thousands of similar pages. By collecting flocks of pigeons in dense clusters, Google is able to process search queries at speeds superior to traditional search engines, which typically rely on birds of prey, brooding hens or slow-moving waterfowl to do their relevance rankings. When a search query is submitted to Google, it is routed to a data coop where monitors flash result pages at blazing speeds. When a relevant result is observed by one of the pigeons in the cluster, it strikes a rubber-coated steel bar with its beak, which assigns the page a PigeonRank value of one. Those pages receiving the most pecks, are returned at the top of the users results page with the other results displayed in pecking order. Integrity Googles pigeon-driven methods make tampering with our results extremely difficult. While some unscrupulous websites have tried to boost their ranking by including images on their pages of bread crumbs, bird seed and parrots posing seductively in resplendent plumage, Googles PigeonRank technology cannot be deceived by these techniques. A Google search is an easy, honest and objective way to find high-quality websites with information relevant to your search.
PigeonRank Frequently Asked Questions How was PigeonRank developed? Brin and Page were the first to recognize that this adaptability could be harnessed through massively parallel pecking to solve complex problems, such as ordering large datasets or ordering pizza for large groups of engineers. Page and Brin experimented with numerous avian motivators before settling on a combination of linseed and flax lin/ax that not only offered superior performance, but could be gathered at no cost from nearby open space preserves. This open space lin/ax powers Googles operations to this day, and a visit to the data coop reveals pigeons happily pecking away at lin/ax kernels and seeds. Pigeons naturally operate in dense populations, as anyone holding a pack of peanuts in an urban plaza is aware. This compactability enables Google to pack enormous numbers of processors into small spaces, with rack after rack stacked up in our data coops. While this is optimal from the standpoint of space conservation and pigeon contentment, it does create issues during molting season, when large fans must be brought in to blow feathers out of the data coop. Removal of other pigeon byproducts was a greater challenge, until Page and Brin developed groundbreaking technology for converting poop to pixels, the tiny dots that make up a monitors display. The clean white background of Googles home page is powered by this renewable process. While no pigeon has actually been confirmed for a seat on the Supreme Court, pigeons are surprisingly adept at making instant judgments when confronted with difficult choices. This makes them suitable for any job requiring accurate and authoritative decision-making under pressure. Among the positions in which pigeons have served capably are replacement air traffic controllers, butterfly ballot counters and pro football referees during the no-instant replay years. Google uses only low-cost, off-the-street pigeons for its clusters. Gathered from city parks and plazas by Googles pack of more than 50 Phds Pigeon-harvesting dogs, the pigeons are given a quick orientation on web site relevance and assigned to an appropriate data coop. Google exceeds all international standards for the ethical treatment of its pigeon personnel. Not only are they given free range of the coop and its window ledges, special break rooms have been set up for their convenience. These rooms are stocked with an assortment of delectable seeds and grains and feature the finest in European statuary for roosting. Google continues to explore new applications for PigeonRank and affiliated technologies. One of the most promising projects in development involves harnessing millions of pigeons worldwide to work on complex scientific challenges.
