Conceptually-grounded mapping patterns for Virtual Knowledge Graphs

Virtual Knowledge Graphs (VKGs) constitute one of the most promising paradigms for integrating and accessing legacy data sources. A critical bottleneck in integration process involves definition, validation, maintenance mapping assertions that link sources to a domain ontology. To support management mappings throughout their entire lifecycle, we identify comprehensive catalog sophisticated patterns emerge when linking databases ontologies. do so, build on well-established methodologies studied management, analysis, conceptual modeling. These are extended refined through analysis concrete VKG benchmarks real-world use cases, considering inherent impedance mismatch between We validate our considered scenarios, showing it covers vast majority present therein.
