摘要

En 中文

地球观测（EO）数据的发布和传播随着卫星发射数量的增加而持续增长。openEO是使用Web API查询EO数据（以数据立方体形式）的最知名平台之一。为了真正体现价值，EO数据通常需要与其他数据源结合，特别是关系数据库。知识图谱提供了一种弥合EO数据与这些附加源之间语义差距的方法。然而，由于EO数据量巨大，集成查询的执行可能会遇到可扩展性问题。在本文中，我们提出通过使用虚拟知识图谱来应对这一挑战——一种将数据呈现给终端用户的知识图谱范式，同时保持数据在其原始来源中，而不是将其物化成图形形式。我们通过实现一个原型解决方案来展示我们方法的可行性，并在真实世界的openEO示例上对其进行测试。
