Current barriers hindering data-driven discoveries in deep-time Earth (DE) include: substantial volumes of DE data are not digitized; many DE databases do not adhere to FAIR (findable, accessible, interoperable and reusable) principles; we lack a systematic knowledge graph for DE; existing DE databases are geographically heterogeneous; a significant fraction of DE data is not in open-access formats; tailored tools are needed. These challenges motivate the Deep-Time Digital Earth (DDE) program initiated by the International Union of Geological Sciences and developed in cooperation with national geological surveys, professional associations, academic institutions and scientists around the world. DDE’s mission is to build on previous research to develop a systematic DE knowledge graph, a FAIR data infrastructure that links existing databases and makes dark data visible, and tailored tools for DE data, which are universally accessible. DDE aims to harmonize DE data, share global geoscience knowledge and facilitate data-driven discovery in the understanding of Earth''s evolution. 相似文献

ABSTRACT The Department of Energy (DOE) Carbon Sequestration Regional Partnerships are generating the data for a “carbon atlas” of key geospatial data (carbon sources, potential sinks, etc.) required for rapid implementation of carbon sequestration on a broad scale. The NATional CARBon Sequestration Database and Geographic Information System (NatCarb) provides Web-based, nation-wide data access. Distributed computing solutions link partnerships and other publicly accessible repositories of geological, geophysical, natural resource, infrastructure, and environmental data. Data are maintained and enhanced locally, but assembled and accessed through a single geoportal. NatCarb, as a first attempt at a national carbon cyberinfrastructure (NCCI), assembles the data required to address technical and policy challenges of carbon capture and storage. We present a path forward to design and implement a comprehensive and successful NCCI. 相似文献

ABSTRACT We live in a time of great change, an increasingly global society, knitted together by pervasive communications and transportation technologies and driven by the exponential growth of new knowledge. It is a time of challenge and contradiction, as an ever-increasing human population threatens global sustainability; a global, knowledge-driven economy places a new premium on workforce skills through phenomena such as off-shoring; governments place increasing confidence in market forces to reflect public priorities even as new paradigms such as open-source technologies challenge conventional free-market philosophies; shifting geopolitical tensions driven by the great disparity in wealth and power about the globe, national security, and terrorism. (Friedman, 2005) Yet it is also a time of unusual opportunity and reason for optimism as these same technologies enable the formation of new communities and social institutions, better able to address the needs of our society. 相似文献

ABSTRACT The future of research libraries will be shaped by broader developments at research universities in the areas of creating, sharing, disseminating, and curating knowledge. Universities face fundamental policy choices in all of these areas that have been recast by developments in information technology. This article discusses trends in digital scholarship practices across the humanities, science, and social science disciplines and examines implications for academic institutions and their research libraries as a means of framing these policy choices. This article originally published in Journal of Library Administration, Vol. 49, Issue 3, pages 227–244, 2009. doi:http://dx.doi.org/10.1080/01930820902785041. 相似文献

2007年开始的美国金融危机不可避免地影响到高等教育信息化的发展路径和战略选择。美国高等教育信息化专业协会EDUCAUSE下属的应用研究中心(ECAR)自2007年之始的一系列报告表明美国高等教育信息化发展呈现出如下的新特点和趋势:高等院校之间越来越积极地开展跨院校的信息技术协作,将信息技术服务外包,充分利用赛博基础设施促进高等院校的教学和科研,积极推进绿色IT和对身份管理(IdM)的日益重视。 相似文献

赛博基础设计作为一个统一的技术平台,具有技术推动、社群牵引、专长拓展等显著优势,为教育打造了一个把有形的物质资源和无形的人力资源整合在一起的新型学习环境——赛博学习环境。赛博学习环境的构建要吸收和借鉴复杂性科学的思想方法,以社会系统工程的方式进行建构。赛博学习环境的基本架构由赛博基础设施、赛博技术工具、数字化学习资源和软件平台以及个性化交互界面等部分组成,借助于数字化通信技术和高性能运算技术,构造了一个新型的数字化学习共享空间。以系统集成为核心特征的赛博学习空间具有开放性和分布式的显著特征,为我们提供了前所未有的学习机遇,比如协作、建模、可视化等。 相似文献
