WolframAlpha, a Fact Search Engine
Yesterday, on 18 May 2009, Wolfram|Alpha is launched. Wolfram Alpha,compared with other search engine, is a little different. If Google try to find the most popular website for certain keyword, Wolfram Alpha is try analize the data we inputed and show the fact about it. Many people predicted that Wolfram Alpha will make Google search engine obsolete. But i doubt it, because those two has its own function.
Fox example, if we type “oil price” on Google, it will show many website about oil price. But if we type “oil price” on Wolfram|Alpha, it will return the oil price, the trends and the convertion rate to the local currency. Personally, i think Wolfram|Alpha is a combination of Wikipedia and Google.
