ITR/IM: A National Earth Science Knowledge Node for Research and Education

作为这一信息技术研究项目的一部分，PIS将设计和开发一个美国地球科学知识节点，它由多样化的、区域规模的、经审查的、高质量的地球科学数据集以及相关的可通过网络访问的信息检索和知识提取工具组成。这一系统将协助(1)地球科学家的研究，(2)课堂上的教育工作者和课程开发，(3)学生的学习和自我发现过程，(4)公众好奇心驱动的终生学习努力，与影响他们日常生活的地球科学现象有关，以及(5)决策者的个案评价和评估。有组织的知识节点将成长为更大规模的、信息技术驱动的研究努力的持久节点，以建立分布式、可互操作、多学科的数据和信息网络，这些研究努力由不同的团体进行，例如美国国家科学基金会的国家科学数字图书馆(NSDL)、地球系统教育数字图书馆(DLESE)、地球信息学的地球科学研究倡议以及建设数字地球的更广泛努力。数据和信息管理一直是共享和访问数据的主要障碍。在规划的知识节点中，高质量、有组织、可随时使用的数据集将消除问题，帮助研究人员节省时间，并有效地交流生成和可用的知识。然而，这一知识系统的最大好处将来自于它能够通过提供数据集和数据处理/分析工具来实现多学科地球科学研究，这些数据将被用来了解复杂的地球系统动力学。该储存库将包括那些不希望长期管理其数据的研究人员的数据集。此外，个人信息系统将开发一个基于网络的地图绘制和分析界面，使用户能够无缝访问感兴趣的数据集，并帮助用户快速有效地检索信息。***

0112655SeberAs part of this Information Technology Research project, the PIs will design and develop a US Earth Science Knowledge Node that is composed of diversified, regional scale, reviewed, high quality earth science data sets, and related web-accessible information retrieval and knowledge extraction tools. This system will assist (1) earth scientists in their research, (2) educators in their classrooms and curriculum development, (3) students in their learning and self discovery process, (4) the public at large in their curiosity driven life-long learning efforts related to earth science phenomena that affect their daily lives, and (5) decision makers in their case evaluations and assessments. The organized knowledge node will grow to become a persistent node to larger scale, information technology driven research efforts undertaken to build distributed, interoperable, multidisciplinary data and information networking by various groups, such as the NSF's National Science Digital Library (NSDL), Digital Library for Earth System Education (DLESE), the earth science research initiative of Geoinformatics, and the broader efforts of building a Digital Earth. Data and information management has always been a major obstacle in sharing and accessing data. High quality, organized, and ready-to-be-used data sets in the planned knowledge node will eliminate problems and help researchers save time and to effectively communicate generated and available knowledge. However, the maximum benefit of this knowledge system will come from its ability to enable multidisciplinary earth science research by providing data sets and data manipulation/analysis tools that will be used to understand complex earth system dynamics. The repository will include data sets from those researchers who do not wish to manage their data for longer terms. In addition, the PIs will develop a web-based mapping and analysis interface that will allow seamless access to data sets of interest and help users retrieve information fast and efficiently. ***
