An ontology formally defines the concepts (the cognitive elements) of a specific domain, usually via defining properties including “is-a” relationships between concepts and other necessary attributes needed to differentiate concepts for a given purpose. There are a number of problems related to knowledge graph completion. Named-entity linking (NEL) [] is the task of linking a named-entity mention from a text to an entity in a knowledge graph.Usually a NEL algorithm is followed by a second procedure, namely relationship extraction [], which aims at …A knowledge graph, also known as a semantic network, represents a network of real-world entities—such as objects, events, situations or concepts—and illustrates the relationship …Chapter 2 details how knowledge graphs are built, implemented, maintained, and deployed.
