DBpedia is a knowledge graph that uses rule-based mappings to extract entities and relations from semi-structured sources [1], faces limitations with batch updates requiring full recomputation of the knowledge graph [2], and has been empirically evaluated to enhance knowledge graph data quality through crowdsourcing and microtasks [3].

claimKnowledge graph solutions often use rule-based mappings to extract entities and relations from semi-structured sources, as seen in DBpedia, Yago, DRKG, VisualSem, and WorldKG.
claimDBpedia and Yago are limited to batch updates that require a full recomputation of the knowledge graph.
referenceEmpirical evaluation on DBpedia by Acosta et al. [234] shows that combining expert crowdsourcing and paid microtasks on Amazon Mechanical Turk is a complementary and affordable way to enhance knowledge graph data quality.
