Space Technology

ling system, Wolfram Alpha, showcased at Harvard University in the US last week, takes the first step in the direction that many consider to be the Holy Grail of the Internet – a global store of information that comprehends and responds to regular language in the same manner a person would.

Although the program is still new, it has already generated massive interest and excitement with technology experts and internet aficionados.

Computer professionals predict that the new search engine will an extraordinary leap in the advancement of the internet. Nova Spivack, an internet and computer expert, advised that Wolfram Alpha could prove equally as popular as Google. "It is really impressive and significant," he wrote. "In fact it may be as important for the web (and the world) as Google, but for a different purpose."

Tom Simpson, of the blog www.convergenceofeverything.com, said: "What are the wider implications exactly? A new paradigm for using computers and the web? Probably. Emerging artificial intelligence and a step towards a self-organizing internet? Possibly... I think this could be big."

Wolfram Alpha can not only provide a direct answer to questions like "how high is Mount Everest?", but it will also produce a neat page of related information – all accurately sourced – such as geographical location and nearby towns, and other mountains, complete with graphs and graphs.

The real ingenuity, however, is in its ability to sort things out "on the fly", according to its British inventor, Dr Stephen Wolfram. If you ask it to compare the height of Mount Everest to the length of the Golden Gate Bridge, it will tell you. Or ask what the weather was like in London on the day John F. Kennedy was assassinated, it will cross-check and offer the answer. Ask it about D sharp major, it will play the scale. Type in "10 flips for four heads" and it will guess that you need to know the probability of coin-tossing. If you need to know when the next solar eclipse over Chicago is, or the exact current location of the International Space Station, it can work it out.

Dr. Wolfram, an award-winning physicist who is currently.

"I\'ve wanted to make the knowledge we\'ve accumulated in our civilization computable," he said last week. "I was not sure it was possible. I\'m a little surprised it worked out so well."

Dr. Wolfram, 49, who was educated at Eton and had completed his PhD in particle physics by the time he was 20, added that the premier of Wolfram Alpha later this month would be only the beginning of the project.

"It will understand what you are talking about," he said. "We are just at the beginning. I think we\'ve got a reasonable start on 90 per cent of the shelves in a typical reference library."

The engine, which will be free to use, computes by drawing on the knowledge of the internet, as well as private databases. Dr. Wolfram said he expected that about 1,000 employees would be needed to keep its databases updated with the latest discoveries and information.

Wolfram Alpha has been designed with experts and intellectuals in mind, so its grasp of popular culture is, at the moment, comparatively weak. The term "50 Cent" caused "absolute horror" in tests, for example, because it confused a discussion on currency with the American rap artist. For this reason alone it is unlikely to provide an immediate threat to Google, which is working on a similar type of search engine, a version of which it launched last week.

"We have a lot number of popular culture information," Dr Wolfram said. "In some senses popular culture information is much more easily computable, so we can figure out who\'s related to who and how tall people are. I fully predict we will have lots of popular culture information. These are linguistic terrors because if you put in books and music a lot of the names collide with other concepts."

He added that to help with that Wolfram Alpha would be using Wikipedia\'s popularity index to decide what users were likely to be interested in.

With Google now one of the world\'s top brands, worth $100bn, Wolfram Alpha has the potential to become one of the biggest names on the planet.

Dr. Wolfram, however, did not rule out working with Google in the future, as well as Wikipedia. "We\'re working to partner with all possible organisations that make sense," he said. "Search, narrative, news are complementary to what we have. Hopefully there will be some great synergies."

Just pretend that someday all information, like historical facts, and important statistics will be kept in computers!
