Knowledge Graph – Introductory Notes-----Overall Concept
1. What is a knowledge graph?
Describes the relationship between various entities or concepts in the real world, which constitutes a massive semantic network graph. Nodes represent entities or concepts, and edges represent attributes or relationships.
2. Three nodes in the knowledge graph
(1) An entity refers to something that is distinguishable and exists independently, such as a person, a class, a city, etc. Different entities have different relationships.
(2) There is not much to say about attributes. For example, if a country is an entity, then its area, population, capital and other factors are its attributes.
3. Architecture of knowledge graph
(1) Logical structure of knowledge graph
(2) Technical architecture of knowledge graph
4. Key technologies of knowledge graph
(1) Knowledge extraction
(2) Knowledge representation learning
(3) Knowledge integration
