ProGOMap: Automatic Generation of Mappings From Property Graphs to Ontologies
IEEE Access, 2021 Property Graph databases (PGs) are emerging as efficient graph stores with flexible schemata. This raises the need to have a unified view over heterogenous data produced from these stores.

Ontology-driven map generalization [PDF]
Journal of Visual Languages & Computing, 2005 Different users of geospatial information have different requirements of that information. Matching information to users' requirements demands an understanding of the ontological aspects of geospatial data. In this paper, we present an ontology-driven map generalization algorithm, called DMin, that can be tailored to particular users and users' tasks ...
