WorldWideScience.org is a global science search engine ( Academic databases and search engines) designed to accelerate scientific discovery and progress by accelerating the sharing of scientific knowledge. Through a multilateral partnership, WorldWideScience.org enables anyone with internet access to launch a single-query search of national scientific databases and portals in more than 70 countries, covering all of the world’s inhabited continents and over three-quarters of the world’s population. From a user’s perspective, WorldWideScience.org makes the databases act as if they were a unified whole.
WorldWideScience.org implements federated searching to provide its coverage of global science and research results. Federated searching technology allows the information patron to search multiple data sources with a single query in real time. It provides simultaneous access to " deep web" scientific databases, which are typically not searchable by commercial search engines. In June 2010, WorldWideScience.org implemented multilingual translations capabilities. Using Microsoft's Bing Translator, Multilingual WorldWideScience.org offers the user the ability to search across databases in ten languages and then have the results translated into their preferred language. "One to many" and "many to one" machine translations can be performed for Arabic, Chinese, English, French, German, Japanese, Korean, Portuguese, Russian, and Spanish.
