PageRank

PageRank
Algorithm used by Google Search to rank web pages PageRank (PR) is an algorithm used by Google Search to rank web pages in their search engine results. It is named after both the term "web page" and co-founder Larry Page. PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. Currently, PageRank is not the only algorithm used by Google to order search results, but it is the first algorithm that was used by the company, and it is the best known.[2][3] As of September 24, 2019, all patents associated with PageRank have expired.[4] Description[edit] A PageRank results from a mathematical algorithm based on the webgraph, created by all World Wide Web pages as nodes and hyperlinks as edges, taking into consideration authority hubs such as cnn.com or mayoclinic.org. History[edit] The eigenvalue problem behind PageRank's algorithm was independently rediscovered and reused in many scoring problems. Algorithm[edit] where At Related:  davidchernofsky

Exclusive: How Google's Algorithm Rules the Web | Wired Magazine Want to know how Google is about to change your life? Stop by the Ouagadougou conference room on a Thursday morning. It is here, at the Mountain View, California, headquarters of the world’s most powerful Internet company, that a room filled with three dozen engineers, product managers, and executives figure out how to make their search engine even smarter. This year, Google will introduce 550 or so improvements to its fabled algorithm, and each will be determined at a gathering just like this one. You might think that after a solid decade of search-market dominance, Google could relax. Still, the biggest threat to Google can be found 850 miles to the north: Bing. Team Bing has been focusing on unique instances where Google’s algorithms don’t always satisfy. Even the Bingers confess that, when it comes to the simple task of taking a search term and returning relevant results, Google is still miles ahead. Google’s response can be summed up in four words: mike siwek lawyer mi.

Deep Web Intelligence We are finding many different industries are able to capitalize on Data-as-a-Service (DaaS). In this post we’ll uncover how a mining company is using BrightPlanet’s Data-as-a-Service model to monitor the Ebola health outbreak to keep their expatriates informed and out of harm’s way with the use of one dataset. You’ll see what type of data is harvested and how it is enriched to make it usable. Continue reading At BrightPlanet, we receive a number of questions about how BrightPlanet’s technology differs from our biggest competitors. People will commonly see companies like Kapow and Connotate and assume that our technologies are in direct competition. In this post, we hope to give you an understanding of how extraction companies and BrightPlanet’s harvesting technology don’t compete, as one may think, and explore the advantages of each individual technology.

New York Times Exposes J.C. Penney Link Scheme That Causes Plummeting Rankings in Google Today, the New York Times published an article about a search engine optimization investigation of J.C. Penney. Perplexed by how well jcpenney.com did in unpaid (organic) search results for practically everything the retailer sold, they asked someone familiar with the world of search engine optimization (SEO) to look into it a bit more. The investigation found that thousands of seemingly unrelated web sites (many that seemed to contain only links) were linking to the J.C. The New York Times presented their findings to Google. J.C. So where did J.C. “Link Schemes” and the Google Webmaster Guidelines The web is big. Google was launched on a foundation of PageRank: the idea that people link to things they like and find valuable, so a page with a lot of links to it is probably more useful than a page without very many links. Over time, as site owners realized how valuable it was to rank well in Google search results, some began hatching “link schemes”. Everyone, that is, except Google.

How Google made the world go viral The first thing ever searched on Google was the name Gerhard Casper, a former Stanford president. As the story goes, in 1998, Larry Page and Sergey Brin demoed Google for computer scientist John Hennessy. They searched Casper’s name on both AltaVista and Google. The former pulled up results for Casper the Friendly Ghost; the latter pulled up information on Gerhard Casper the person. What made Google’s results different from AltaVista’s was its algorithm, PageRank, which organized results based on the amount of links between pages. Google officially went online later in 1998. This year, The Verge is exploring how Google Search has reshaped the web into a place for robots — and how the emergence of AI threatens Google itself. There is a growing chorus of complaints that Google is not as accurate, as competent, as dedicated to search as it once was. For two decades, Google Search was the largely invisible force that determined the ebb and flow of online content. But it wasn’t an anomaly.

The Small-World Phenomenon: An Algorithmic Perspective 1 Jon Kleinberg 2 Abstract: Long a matter of folklore, the ``small-world phenomenon'' -- the principle that we are all linked by short chains of acquaintances -- was inaugurated as an area of experimental study in the social sciences through the pioneering work of Stanley Milgram in the 1960's. This work was among the first to make the phenomenon quantitative, allowing people to speak of the ``six degrees of separation'' between any two people in the United States. Since then, a number of network models have been proposed as frameworks in which to study the problem analytically. But existing models are insufficient to explain the striking algorithmic component of Milgram's original findings: that individuals using local information are collectively very effective at actually constructing short paths between two points in a social network. The Small-World Phenomenon. Milgram's basic small-world experiment remains one of the most compelling ways to think about the problem. The Present Work. .

Google bomb A Google bomb on March 31st, 2013. Despite Google's intervention, some of the first search results still refer to Bush. The terms Google bomb and Googlewashing refer to the practice of causing a web page to rank highly in search engine results for unrelated or off-topic search terms by linking heavily. In contrast, search engine optimization (SEO) is the practice of improving the search engine listings of web pages for relevant search terms. It is done for either business, political, or comedic purposes (or some combination thereof).[1] Google's search-rank algorithm ranks pages higher for a particular search phrase if enough other pages linked to it use similar anchor text (linking text such as "miserable failure"). By January 2007, however, Google tweaked its search algorithm to counter popular Google bombs such as "miserable failure" leading to George W.

Howard Rheingold's insight:

Every time you Google, you are using an augmented collective intelligence engine. PageRank is the algorithm that weights the inbound links to web pages as "votes" for that page's significance. Certainly no blogger thinks "I'm making Google more intelligent and contributing to its value" when adding a link to a website. More likely, they think "this is a valuable link for the attention of my public." By figuring out how to measure the informational value of websites through a mathematical manipulation of its inbound links, Google created a collective intelligence engine (and, to the benefit of Google's stockholders, created an attention magnet for displaying advertising messages -- a case of a public good that is also a concentrator of private wealth. by noosquest Mar 30
