Rule of inference logic

WebbIf we want to apply logic rules in KG inference, we must first pre-define a rule set for KGs and use it to infer the facts that are already present in the KGs. However, the set of rules used in this approach is usually incomplete when dealing with KGs with more complex structures, and different rules always infer some utterly contradictory conclusions.
