Abstract
Knowledge graphs have shown great application value in many fields. A geospatial knowledge graph is proposed in this paper to facilitate site selection and environmental monitoring of thematic facilities. A data model of the knowledge graph which integrates thematic geospatial data products and the Internet information is put forward firstly. Then a two-layer logical framework consisting of a schema layer and a data layer is designed for the geospatial knowledge graph. Design of the schema layer and ontology of the knowledge graph is investigated, through which entity and attribute characteristics and relation structure of the thematic facilities are examined carefully. The techniques to construct the data layer of the knowledge graph including information extraction, knowledge fusion, update, reasoning as well as knowledge storage are also investigated and discussed. The future key research work of the geospatial knowledge graph for thematic facilities is provided at the end.
