CREST-Cyber-ShARE Center of Excellence: A Center for the Sharing of Cyber-Resource to Advance Science and Education

网络共享中心将汇集计算机科学、计算数学、教育、地球科学和环境科学方面的专家，以应对向科学家和网络基础设施（CI）的其他用户提供信息的挑战，使他们能够对他们检索的资源做出明智的决定，并有信心使用基于CI的应用程序的结果。Cyber-Share团队将进行创新研究，以促进基于CI的应用程序的开发，并通过增强CI结果的出处信息，信任建议和不确定性水平（被认为是CI成功的关键领域）来增加科学家的使用;通过创建以科学家为中心的工具和工件;并通过将CI资源贡献给适当的CI门户网站。此外，协同和多学科的子项目将增进以下方面的知识：（一）来源，利用学科专家的成果获取关于不确定性和信任的知识;（二）通过研究基于CI的技术和方法，以不同的准确度和敏感度整合数据，从而了解地球的物理特性; iii）通过针对环境现象和过程的改进表征，优化生态和环境网络中的数据流和传感器阵列。

The Cyber-ShARE Center will bring together experts in computer science, computational mathematics, education, earth science, and environmental science to address the challenge of providing information to scientists and other users of cyber-infrastructure (CI) that allows them to make informed decisions about the resources that they retrieve and to have confidence in using results from CI-based applications. The Cyber-ShARE team will conduct innovative research to facilitate the development of CI-based applications and increase their use by scientists by enhancing CI results with provenance information, trust recommendations, and uncertainty levels (areas that are recognized as essential for the success of CI); by creating scientist-centered tools and artifacts; and by contributing CI resources to appropriate CI portals. In addition, the synergistic and multi-disciplinary subprojects will advance knowledge in i) provenance to capture knowledge about uncertainty and trust using results from discipline experts; ii) the physical properties of the Earth by studying CI-based techniques and approaches for integrating data with varying accuracy and sensitivity; iii) optimization of data streams and sensor arrays in ecological and environmental networks by targeting improved characterization of environmental phenomena and processes.
