项目摘要

Making data discovery more efficient, comprehensive and user-friendly is a critical challenge articulated by geoscientists as well as researchers in other fields. While information discovery portals and search engines have been developed for many data repositories, and systems that simultaneously search multiple resources have been created, cross-disciplinary data discovery remains a serious issue. It becomes especially acute with rapid increases in the volume and diversity of observations, reflecting different components of the Earth System and collected by multiple research groups, government organizations and commercial companies. The main goal of the EarthCube Data Discovery Hub project is to greatly reduce the time and effort necessary to locate and evaluate geoscience information resources across disciplines, and increase the value of investment in data generation by promoting data reuse and reducing duplication of effort. Project outcomes will benefit a wide group of scientists by providing them a user-friendly and powerful gateway to information resources across multiple data facilities and community contributions, and mechanisms for improving the system to answer their research queries in a consistent manner. The project will also benefit geoscience research in several ecosystems that are being used as examples to test the data tools being developed, including rivers, coral reefs and other marine ecosystems, and the critical zone where rock, soil, water, air and living organisms interact.The EarthCube Data Discovery Hub will be developed as a comprehensive data discovery and content enhancement system, which will leverage improved and community-curated metadata descriptions and integrate previously unregistered information sources. The project will further extend, improve and operationalize the inventory catalog developed in an earlier CINERGI (Community Inventory of EarthCube Resources for Geoscience Interoperability) project, which currently includes over 2 million metadata documents from multiple sources. The key technological innovations include: pioneering the development of an automated cross-domain metadata augmentation and curation pipeline enabled by a large integrated geoscience ontology; mechanisms for ?deep registration? of geoscience data from different sources based on a novel data type registry; an online use case management system; and a methodology for processing several types of complex geoscience queries that cannot be answered by existing systems. In addition, the project will support scientific progress in several representative cross-disciplinary research scenarios, using the contexts of river geochemistry, coral reef and other marine ecosystem analysis, and critical zone science. The project will implement innovative community engagement mechanisms, including community annotation of automatically curated metadata, iterative improvement of geoscience ontology based on community feedback, and joint development of cross-disciplinary use cases semantically aligned with data descriptions.

让数据发现更加高效、全面和用户友好是地球科学家以及其他领域的研究人员提出的一项关键挑战。尽管已经为许多数据存储库开发了信息发现门户和搜索引擎，并且创建了同时搜索多个资源的系统，但跨学科的数据发现仍然是一个严重的问题。随着反映地球系统不同组成部分并由多个研究小组、政府组织和商业公司收集的观测数据的数量和多样性迅速增加，这一问题变得尤其严重。 EarthCube数据发现中心项目的主要目标是大大减少跨学科定位和评估地球科学信息资源所需的时间和精力，并通过促进数据重用和减少重复工作来增加数据生成的投资价值。项目成果将为广大科学家提供一个用户友好且强大的门户，以获取跨多个数据设施和社区贡献的信息资源，以及改进系统以一致的方式回答他们的研究问题的机制，从而使广大科学家受益。该项目还将有利于几个生态系统的地球科学研究，这些生态系统被用作测试正在开发的数据工具的例子，包括河流、珊瑚礁和其他海洋生态系统，以及岩石、土壤、水、空气和生物体相互作用的关键区域EarthCube数据发现中心将被开发为一个全面的数据发现和内容增强系统，它将利用改进的和社区策划的元数据描述，并集成以前未注册的信息源。该项目将进一步扩展、改进和实施早期 CINERGI（地球科学互操作性地球立方资源社区清单）项目中开发的清单目录，该目录目前包括来自多个来源的超过 200 万个元数据文档。关键技术创新包括：率先开发由大型综合地球科学本体支持的自动化跨域元数据增强和管理管道； “深度注册”机制基于新型数据类型注册表的不同来源的地球科学数据；在线用例管理系统；以及一种处理现有系统无法回答的几种复杂地球科学查询的方法。此外，该项目还将利用河流地球化学、珊瑚礁和其他海洋生态系统分析以及关键区域科学的背景，支持几个代表性跨学科研究方案的科学进展。该项目将实施创新的社区参与机制，包括自动管理元数据的社区注释、基于社区反馈的地球科学本体的迭代改进，以及在语义上与数据描述一致的跨学科用例的联合开发。
