WebbIt is shown that complexity of reasoning tasks in atemporal probabilistic KG carry over to the bitemporal setting and coalescing and scalability of marginal and MAP inference are … WebbKnowledge graphs (KG) model relationships between entities as labeled edges (or facts). They are mostly constructed using a suite of automated extractors, thereby inherently leading to uncertainty in the extracted facts. Modeling the uncertainty as probabilistic confidence scores results in a probabilistic knowledge graph.
