The Knowledge Graph is the knowledge base Google uses to improve the quality of its search engine. This technology is based on semantic science and information for it is collected from many sources, such as Wikipedia, CIA World Factbook, and Freebase.
The Knowledge Graph is similar in function to other search engines that answer a user’s question, such as Wolfram, Dbpedia, and Alpha. The program network contains more than 570 million different objects, 18 billion specific facts, and, accordingly, relationships between various system objects, which help the program to understand the meaning of the client’s request.
The Knowledge Graph provides the user with detailed information on the subject of the request, as well as a list of third-party sites that may be useful for research. The bottom line is to make it easier for users to collect information about a topic of interest to them and remove the need to independently go to other sites in search of information.
The Knowledge Graph was added to the Google search engine back in 2012, and in 2014 the company integrated the system with the Google Maps program.
