美国能源部、英国图书馆以及其他8个参与国22日共同开启了从15个国家入口接入的在线科学信息全球通道。 网址为http://www.WorldWideScience.org 它可以为人们、研究人员以及任何对科学感兴趣的人提供科学信息搜索入口，以便他们能够轻松访问那些使用普通搜索技术不能访问的网站。例如Google、雅虎和许多其他商业搜索引擎所使用的搜索技术。 美能源部科学部副部长雷蒙德·奥尔巴奇称：“许多通过普通搜索引擎无法获知和得到的信息都可以在过剩的资源中通过全球性科学搜索得到结果。”他继续称：“这种国际伙伴关系将通过快速和便利的方式创建一个知识宝库，它将使我们现有的知识获得更大程度的增值。” 依赖于一种被称之为联合搜索的创新技术，WorldWideScience.org将为科学信息用户提供一种单入口点，仅通过一次询问就能更进一步搜索平行的科学入口，既节省时间又不费力。随着WorldWideScience.org的不断扩展，它将利用现有的技术搜索更广泛的分布于全球的科学信息集群，并利用一些迫切的通道将一些更小的、不为人知的却具有较高价值的科学资源连接起来。 依照美国机构间科学入口Science.gov模式（这种模式的科学信息依赖于美国各参与机构所出版的刊物），WorldWideScience.org也将依赖于每个参与国所出版的科学资源。 美国对WorldWideScience.org的贡献就是Science.gov。它原本是美国政府的一次性可搜索入口，可连接主要的美联邦科学机构的科学数据库。除美国和英国以外，刚刚创立的WorldWideScience.org入口还为澳大利亚、巴西、加拿大、丹麦、法国、德国、日本和荷兰提供了英语信息搜索权限。 创建WorldWideScience.org的意图在于使其成为世界级的网络工具，让任何地方的任何一位科学家或任何人都能轻松地获得任一种语言或任一国家的搜索结果。 作为美能源部科学办公室的一个项目，WorldWideScience.org是由美科技情报办公室开发的，现在该机构也负责它的维护工作。科技情报办公室在提供分布、纵深的网络数据库搜索方面有着丰富的经验，它同时在Science.gov和其他一些网络产品的研发工作中扮演着重要的角色。这些网络产品每年为科学家和公民提供5,000多万次的搜索服务。 美能源部科学办公室是国家自然科学基础搜索方面唯一的最大支持者。它帮助美国通过广泛的科学规程确保其世界领导地位。想获知更多信息，请登录美能源部科学办公室网站。 http://www.WorldWideScience.org |

http://www.doe.gov/news/5153.htm Global Science Gateway Now Open WorldWideScience.org opens public access to more than 200 million pages of international research information WASHINGTON, DC—The U.S. Department of Energy (DOE) and the British Library, along with eight other participating countries, today opened an online global gateway to science information from 15 national portals. The gateway, WorldWideScience.org, gives citizens, researchers and anyone interested in science the capability to search science portals not easily accessible through popular search technology such as that deployed by Google, Yahoo! and many other commercial search engines. “Scientific research results are archived globally in a plethora of sources, many unknown and unreachable through usual search engines,” Dr. Raymond L. Orbach, DOE Under Secretary for Science, said. “This international partnership will open up this vast reservoir of knowledge in a rapid and convenient manner, something that will add great value to our existing knowledge.” Relying on a novel technology called federated search, WorldWideScience.org gives science information consumers a single entry point for searching far-reaching science portals in parallel, with only one query, saving time and effort. As WorldWideScience.org grows, it will capitalize on existing technology to search vast collections of science information distributed across the globe, enabling much-needed access to smaller, less well-known sources of highly valuable science. Following the model of Science.gov, the U.S. interagency science portal that relies on content published by each participating U.S. agency, WorldWideScience.org will rely on scientific resources published by each participating nation. The U.S. contribution to WorldWideScience.org is Science.gov, the U.S. government’s one-stop searchable portal to major science databases of federal science agencies. In addition to the U.S. and the U.K., the inaugural WorldWideScience.org portal provides access to research information in English from Australia, Brazil, Canada, Denmark, France, Germany, Japan and the Netherlands. The intent is for WorldWideScience.org to become a world-class Web facility that lets any scientist, any citizen, anywhere, easily find the research results of any nation in any language. WorldWideScience.org was developed and is maintained by the Office of Scientific and Technical Information (OSTI), a program within DOE’s Office of Science. OSTI has extensive experience in offering searching of distributed, deep Web databases, having played a central role in the development of Science.gov and other Web products that scientists and citizens access over 50 million times per year. DOE's Office of Science is the single largest supporter of basic research in the physical sciences in the nation and helps ensure U.S. world leadership across a broad range of scientific disciplines. Additional information is available at the Office of Science. |
