On March 5 , 2009 , Stephen Wolfram wrote a post in his fellowship ’s blog about a novel ware he ’d been working on . It would n’t be long , Wolfram write , before Wolfram Research would be releasing a raw locomotive engine capable of answering questions written in rude language .
hunting on theInternetis dominated byGoogle , at least in the United States . In March 2009 , the company held 64.2 percent of the U.S. search market , followed by Yahoo ’s 15.8 percent and Windows Live ’s 10.3 per centum [ source : Nielsen Online ] . Wolfram ’s proclamation made newspaper headline on tech Web internet site . But if monster such as Yahoo andMicrosoftcan’t knock Google off its perch , why does anyone care about Wolfram Research and its new Web land site ?
In truth , it ’s probably part because the great unwashed like the old David - and - Goliath type of chronicle , where the little hombre takes on the big guy and come through , despite impossible betting odds . But in this story , David ’s stimulate a great bad slingshot . In 1988 , Wolfram Research released a piece of software called Mathematica , a extremely respected computer program that helps the great unwashed misrepresent data in all kinds of ways . In creating Wolfram|Alpha , Wolfram Research detect a way to manipulate data in exploiter ' query and show result in fresh , originative ways . And because it ’s come from a well - make out and honest source , people perked up their ears and mind when Stephen Wolfram made his announcement .
So just what is Wolfram|Alpha ? What does it do , and is it any threat to Google ?
Computational Knowledge Engine
Wolfram|Alpha plunge on May 15 , 2009 . Many other users expect it to work like asearch enginecomplained that the site would n’t return results to some dewy-eyed queries . But unlikeGoogle– and other search sites – Alpha is n’t an attempt to catalog the world ’s information . Instead , it ’s what Wolfram Research calls a computational knowledge railway locomotive .
Traditional search engines creep the connection for site and add them to their directory . Algorithmsbuilt into the code that power these hunting engines grade pages higher or lower establish on several factors . One is the numeral of hoi polloi who dawn on the tie-in from the search engine results page ( SERP ) . Another is the number of third - company World Wide Web land site that link to that site . If you create a public WWW site , there ’s a adequate chance it ’ll end up on a search railway locomotive without your accept to do a thing to get it listed - as long as there are radio link to it from other sites
Wolfram|Alpha does n’t rake the Web for material . Instead , it relies on licensed databases and substance entered , tag and cataloged by Wolfram Research employees . According to the caller , there were more than 10 trillion individual chunks of data on the Alpha servers at the time of the site ’s launching [ source : Wolfram Research ] . Wolfram Research employees vet all information to ensure its accuracy before it ’s added to the Wolfram|Alpha databases .
To get that information , a soul type a inquiry into the search box on the Wolfram|Alpha home varlet and presses the equals sign to the right – the equals sign is a cue that there ’s math travel on in the background knowledge . Alpha then appear searches for stand for data in its databases .
effect can be quite elementary : Enter the name of a urban center , and you ’ll get the time of twenty-four hour period and weather information , as well as population and elevation above ocean level . Input several urban center figure and you ’ll get a mesa that enables you to compare them . If you type in the name of an creature , you ’ll get the average size , substitute public figure , scientific name and even a breakdown of its taxonomy . Again , if you ask Alpha for the names of different animals , you ’ll get a table comparing them , and you ’ll even see how they ’re tie in taxonomically .
Scientific and mathematical problem are easy for Alpha to wield . In fact , you’re able to ask the computational knowledge engine to infer a calculus problem and not only will it tell you the answer , it will also show you what stairs are require to clear it .
But remember , Wolfram|Alpha is n’t a search locomotive engine , which think of that if you want to incur picture of famous person , the tacky price on a flight to London or articles written about a specific topic , you postulate to habituate a lookup locomotive . Alpha is design for you to ask it a question and get a factually right answer , along with a ocular interpretation of that reply .
What’s behind Wolfram|Alpha?
When Stephen Wolfram was just 15 , he had his first scientific paper publish . He earned his PhD in theoretical physics from the California Institute of Technology when he was 20 . Wolfram receive a MacArthur Prize Fellowship in 1981 , and that ’s ripe about the prison term he started looking into the systems of nature and how complex they are .
Wolfram began usingcomputersin 1973 . In 1986 his company , Wolfram Research , unblock the first version of its well - respectedMathematicasoftware . Mathematica is used in all form of industries , including engineering , scientific discipline and finance , and is up to of high - end computation and modeling . Thealgorithmsfrom Mathematica are used to calculate and expose search results in Wolfram|Alpha .
In 2002 , Stephen Wolfram published a book call " A New Kind of Science , " in which he explains his belief that simple rules can explicate complex problems . As Wolfram explicate in his March 2009blogpost , the principles in his book and the computational superpower provided by the Mathematica package are what led him to consider that it was possible to create Alpha .
One of Wolfram ’s goals was to make it possible " to demand a information processing system any actual question , and have it compute the solvent " [ author : Wolfram ] . But born language processing is n’t easy . According to Wolfram Research , the Web site usesalgorithmsand analyzing software to key out radiation pattern in datum . This help oneself it name shorthand term that people use to ask questions . This help it guess what you ’re test to find when you enter a query in its search box .
As an example , if you type in " GEC , " Alpha assumes you ’re asking about the General Electric Corporation . If you separate the letters with commas , you get musical preeminence and a visualization of where they are on the keyboard . flick the " Play eminence " link to hear the procession – and perhaps if you ’re an American , you’re able to guess which major boob tube web GE is the dominant corporate parent of . Wolfram|Alpha is guessing , by the way in which you infix your search condition , what information you ’re trying to determine .
Wolfram Research say Alpha is based on four pillars : information , dynamic computation , innate language understanding and computational aesthetics . The data are handle by Wolfram Research employees . The relaxation is done on the back end via Mathematica .
To crunch those variety of number , you ’re going to need serious computer power . Wolfram Research has a supercomputer ( really , two of them ) build using Dell ironware customize by a company called R Systems . The machine , key out R Smarr , is the world ’s 66th - fastest supercomputer ( as of this writing ) . With 4,608 processor cores , R Smarr can perform 39.6 trillion operations per second . There are 576 quadrangle - marrow Intel " Harpertown " Xeon chips inside and each R Smarr supercomputer has 65,536 GB of random - admittance memory , or RAM [ source : Shankland ] .
Wolfram|Alpha vs. Google
If so many people want to pit hunting engine giantGoogleagainst the newcomer , why do n’t we take a look at the two of them and see how they stack up ?
fit in to Wolfram|Alpha ( which used Alexa.com as a source ) , at the metre of this written material , google.com get 3.8 billion pageboy views per daytime . Alpha , on the other hand , gets 13 million pageboy views . Google ’s No . 1 on the Web , compare to Alpha ’s 568th .
Wolfram|Alpha may need to find oneself other ways to bring forth income . There are around 250 hoi polloi run behind the scenes on the site [ source : Shankland and Needleman ] . Curating data by hired man is high-priced than sending spiders out to catalogue entanglement sites . It ’s also more clock time - consuming . The database Alpha used at launch submit three to four yr to progress [ beginning : Beaumont ] .
It ’s potential , too , that Wolfram Research may deal customize subscriptions to organizations that want to liken proprietary information with the Alpha database . There ’s also an program scheduling port , or API , that will allow developers to blend the functionality of their sites with Wolfram|Alpha [ source : Shankland and Needleman ] .
But Google co - founder and President of Technology Sergey Brin catch a monstrance of the Wolfram|Alpha technology by Stephen Wolfram himself prior to the site ’s launch [ rootage : Levy ] . This suggests the two might find a way to partner . On the other hand , some think Google Squared , a lookup characteristic that will enable Google users to compare information in ways alike to those used by Alpha , shows a desire to crush the upstart . However , Google Squared evaluates datum found online , not the single proprietary databases , as Alpha does [ source : Talbot ] .
As Stephen Wolfram said in his March 2009 blog post , Alpha is a massive project that will never be finish . meter will tell if it manages to carve out a recess inInternetusers ' inwardness or whether its technology will end up underpinning lookup efforts on other situation .
