Knowledge Graphs are a type of artificial intelligence (AI) computer system designed to store, organize, and understand large amounts of information. In particular, they are used in applications such as web search, recommender systems, natural language processing, data mining, and other AI tasks. Normally, knowledge graphs consist of a set of nodes, which represent entities in the domain, and edges, which connect the nodes and represent relationships between the entities. The nodes usually represent real-world things, such as people, places, or documents, while the edges represent connections such as family relationships, social connections, or similarity among documents.
Knowledge graphs help computers understand relationships between entities in a way that is more intelligent than traditional databases that store information in tables and rows. They allow computers to understand and answer questions, such as “Who is the mother of Paul?” or “What is the capital of India?”. By modeling relationships between entities, knowledge graphs can store and organize data more effectively than traditional databases, making it easier for computers to process and search information.
In addition, knowledge graphs enable computers to process natural language requests or questions. For example, they can answer questions such as “Who wrote the book Alice in Wonderland?” or “What type of music does Taylor Swift sing?”. The ability to answer these types of questions enables computers to provide a natural language interface between users and large quantities of data stored in databases.
Knowledge graphs are used in a variety of computer applications, such as search engines, e-commerce sites, recommender systems, and natural language processing. For example, Google’s search engine uses its Knowledge Graph to better understand search queries and deliver more accurate search results. Amazon’s Alexa can also use knowledge graphs to answer voice commands.
Overall, knowledge graphs are powerful AI tools that enable computers to better understand relationships between entities and answer natural language queries. As AI technologies continue to become more sophisticated, knowledge graphs will become increasingly important in many computer applications.
