摘要：

【目的】对地观测领域仅共享科学数据还不能为用户直接提供解决问题的方案,还需要实现面向问题或者应用提供知识共享支持,对地观测知识枢纽的建立能有效支持共享对地观测领域的知识要素,促进对地观测知识（特别是模型、算法表达的隐性知识）的重用,提升应用对地观测知识解决重大问题的能力。【文献范围】本文通过文献调查,获取了知识枢纽以及对地观测领域知识枢纽的主要文献。【方法】采用文献分析法,分析了对地观测知识枢纽的概念内涵、实现技术和方法。【结果】总结了对地观测知识枢纽的主要内容、特点和功能,归纳了对地观测知识枢纽的实现方法,展望了对对地观测知识枢纽的应用。【局限】由于目前尚无公开可用的对地知识枢纽系统,可能对目前知识枢纽的具体实现技术表述不全。【结论】对地观测知识枢纽是对地观测数据共享的发展新趋势,能有效促进对地观测知识重用,将成为未来对地观测领域广泛应用的知识共享基础设施。

Abstract:

[Objective] The sharing of scientific data in the field of earth observation cannot directly provide users with solutions to problems, it is necessary to provide knowledge sharing support for problems or applications. The establishment of an earth observation knowledge hub can effectively support the sharing of knowledge elements in the field of earth observation, promote the reuse of earth observation knowledge (especially the implicit knowledge expressed by models and algorithms), and improve the ability to apply earth observation knowledge to solve major problems. [Coverage] This paper obtains the literature on knowledge hub and earth observation field knowledge hub through the literature survey. [Methods] The concept connotation, implementation technology, and method of earth observation knowledge hub are analyzed utilizing the literature analysis method. [Results] The concept, main content, characteristics, and functions of the earth observation knowledge hub are summarized. The realization methods of the earth observation knowledge hub are presented. The application of the earth observation knowledge hub is forecasted. [Limitations] Since there is no publicly available knowledge hub system, the specific realization technology of the knowledge hub may not be fully described. [Conclusions] Earth observation knowledge hub is a new development trend of earth observation data sharing, which can effectively promote the knowledge reuse of earth observation and will become a knowledge sharing infrastructure widely used in the field of earth observation in the future.

Key words: knowledge hub, earth observation, knowledge sharing
