Knowledge Graphs on the Web -- an Overview

Understand

Knowledge Graphs are an emerging form of knowledge representation.

• While Google coined the term Knowledge Graph first and promoted it as a means to improve their search results, they are used in many applications today.
• In a knowledge graph, entities in the real world and/or a business domain (e.g., people, places, or events) are represented as nodes, which are connected by edges representing the relations between those entities.
• While companies such as Google, Microsoft, and Facebook have their own, non-public knowledge graphs, there is also a larger body of publicly available knowledge graphs, such as DBpedia or Wikidata.
