Google has a long history of April Fools' Day hoaxes, but this year they’re somewhat different:
Google Japan released an April Fools’ joke by adding a special Universal Search result for Dajare, "a kind of comic Japanese wordplay, similar in spirit to an English pun relying on similarities in the pronunciation of words to create a simple joke". A search for 国内線 (which the Google translator says means “Domestic flights”, though that may be inaccurate) shows the onebox is live in Japan, indeed.
Google China's blog describes a social search engine that would replace Google's algorithms. "We sort of search results purely from a human decision, [without] machine's intervention."
Google Australia announces gDay, a new feature of Google that lets you search today the web pages published tomorrow. "Google spiders crawl publicly available web information and our index of historic, cached web content. Using a mashup of numerous factors such as recurrence plots, fuzzy measure analysis, online betting odds and the weather forecast from the iGoogle weather gadget, we can create a sophisticated model of what the internet will look like 24 hours from now. We can use this technique to predict almost anything on the web – tomorrow's share price movements, sports results or news events. Plus, using language regression analysis, Google can even predict the actual wording of blogs and newspaper columns, 24 hours before they're written!"
Google Korea found a new technology for translating dialects that was integrated in Gmail and Google Talk.
