The Google Knowledge Graph is a system that helps Google understand the relationships between different pieces of information. It organizes data about people, places, and things, allowing users to find relevant information quickly. For example, when you search for a celebrity like Taylor Swift, the Knowledge Graph can display her biography, albums, and related artists. This tool enhances search results by providing a more comprehensive view of a topic. Instead of just showing links, it presents facts and connections, such as the relationship between Taylor Swift and her music label or her awards. This makes it easier for users to get the information they need.
