Spatial principles of knowledge organization have received increasing attention over the past decades due to the fundamental importance of locations in everyday phenomena and a wide variety of emerging spatial data, such as linked open gazetteers and location-based sensor observations. This inspires recent years’ development on knowledge graph–based GeoEnrichment. In this tutorial, we will discuss relevant practices in the KnowWhereGraph, such as how to reuse the OGC GeoSPARQL standard and the Sensor, Observation, Sample, and Actuator (SOSA) ontology in observation-driven geo-ontology engineering, and how the S2 grid system helps achieve spatial data integration across different gazetteers. Participants will learn how knowledge graph—based GeoEnrichment supports knowledge discovery by swiftly answering questions like What is here, What happened here before, and How does this compare to other regions, and builds environmentally intelligent services in application areas, e.g., providing disaster responses for humanitarian relief.
