An Introduction to the World of Knowledge Graphs

There have been quite a few well-established general knowledge graphs.Knowledge engineering with respect to knowledge graphs and graph data in general is becoming a more and more essential component of intelligent systems. Besides entity-centric knowledge, usually organized as Knowledge Graph (KG), events are also an essential kind of knowledge in the world, which trigger the spring up of event-centric knowledge representation form like Event KG (EKG).Specific challenges include understanding knowledge graphs and automation, user experiences of creating and using knowledge graphs for a diverse set of contributors, .Early use of knowledge graphs, before the start of this century, related to building a knowledge graph manually or semi-automatically and applying them for semantic applications, such as search, browsing, personalization, and advertisement.Knowledge graphs (KGs) have emerged as a compelling abstraction for organizing the world’s structured knowledge and for integrating information extracted from multiple data sources. Still, the researc h .Knowledge AssessmentThe knowledge graph (KG) describes the objective world’s concepts, entities, and their relationships in the form of graphs. That is why two years ago we .
