已经提出了许多用于评估链路发现系统性能的真实和合成基准。到目前为止，只有有限数量的链接发现基准针对链接地理空间实体的问题。然而，链接开放数据网的一些最大的知识库，如LinkedGeoData，包含大量的空间信息。已经开发了一些管理空间数据并考虑空间资源的拓扑以及它们之间的拓扑关系的系统。为了评估这些系统处理大量空间数据的能力，并在链接的地理数据云中执行急需的数据集成，必须制定地理空间链接发现的基准。在本文中，我们提出了空间基准生成器SPgen，该生成器可用于测试链路发现系统的性能，该系统处理现有技术DE-9IM（维度扩展九相交模型）中提出的拓扑关系。SPgen实现了二维空间中LineStrings和Polygons之间DE-9IM的所有拓扑关系。提供了与使用SPgen生成的基准的比较分析，以评估和识别AML、OntoIdea、RADON和Silk空间链路发现系统的能力

| 课程简介: |
A number of real and synthetic benchmarks have been proposed for evaluating the performance of link discovery systems. So far, only a limited number of link discovery benchmarks target the problem of linking geo-spatial entities. However, some of the largest knowledge bases of the Linked Open Data Web, such as LinkedGeoData contain vast amounts of spatial information. Several systems that manage spatial data and consider the topology of the spatial resources and the topological relations between them have been developed. In order to assess the ability of these systems to handle the vast amount of spatial data and perform the much needed data integration in the Linked Geo Data Cloud, it is imperative to develop benchmarks for geo-spatial link discovery. In this paper we propose the Spatial Benchmark Generator SPgen that can be used to test the performance of link discovery systems which deal with topological relations as proposed in the state of the art DE-9IM (Dimensionally Extended nine-Intersection Model). SPgen implements all topological relations of DE-9IM between LineStrings and Polygons in the two-dimensional space. A comparative analysis with benchmarks produced using the SPgen to assess and identify the capabilities of AML, OntoIdea, RADON and Silk spatial link discovery systems is provided
