Semantic processing of conceptual models is a focus of research since several years, bridging the disciplines of knowledge-based systems, conceptual modeling, and model-driven software engineering. With the uptake of Knowledge Graphs, the research in this area gained further momentum. In this paper, we introduce a generic and extensible platform that enables the automated transformation of conceptual models into Knowledge Graphs. The platform can transform any model created by a state-of-the-art metamodeling platform (EMF and ADOxx) into standardized Knowledge Graph representations like GraphML, RDF, and OWL. In the paper at hand, we introduce our platform and evaluate it with a corpus of 5.000 UML models that we transform into Knowledge Graphs and subsequently exemplify the rich functionalities enabled by the graph structure by an automated detection of UML model smells.
