There is no single commonly accepted definition of a knowledge graph. Most definitions view the topic through a Semantic Web lens and include these features: • Flexible relations among knowledge in topical domains: A knowledge graph (i) defines abstract classes and relations of entities in a schema, (ii) mainly describes real world entities and their interrelations, organized in a graph, (iii) allows for potentially interrelating arbitrary entities with e… WebBipartite Graph Co-Clustering for Ontology Mapping A bipartite graph has two disjoint vertex sets. Co-clustering a bipartite graph is to simultaneously group several vertices into similar clusters for each vertex set. We use this technique here in order to be able to establish many-to-many mappings between concepts of two ontologies.
