Google Knowledge Graph
The Google Knowledge Graph is a knowledge base that the company uses to provide pertinent information in an infobox that is presented next to its search results. This provides the user with the ability to see the solution at a glance. The data comes from an autonomous process that pulls information from a wide range of sources, including locations, individuals, corporations, and other entities.
Following its first release, Google's Knowledge Graph saw rapid expansion, doubling in size in only seven months after the product's introduction (covering 570 million entities and 18 billion facts). By the middle of 2016, Google said that it had 70 billion pieces of information and had provided a response to "approximately one-third" of the 100 billion queries they processed each month. This had risen to 500 billion information on 5 billion entities by the time May 2020 rolled around.
There is no formal documentation available about the manner in which Google's Knowledge Graph is implemented. Google claims that the information it provides comes from a variety of sources, including the CIA World Factbook and Wikipedia. It is used to provide responses to inquiries that are asked verbally using Google Assistant and Google Home voice searches. It has been criticised for offering responses without attributing or citing any sources for such replies.
On May 16, 2012, Google introduced its Knowledge Graph as a means to greatly boost the value of the information that is returned by Google searches. This was done in order to better serve users. It was initially only offered in the English language, but in December 2012, it was made accessible in Spanish, French, German, Portuguese, Japanese, Russian, and Italian as well. In March of 2017, support for Bengali was added.
Freebase was one of the services that helped fuel the Knowledge Graph.
In August of 2014, New Scientist published an article stating that Google has initiated a project known as Knowledge Vault. Following the article's publication, Google contacted Search Engine Land to clarify that Knowledge Vault was not an operational Google service but rather a study paper. According to Search Engine Land, there are hints that Google is doing research and development on "multiple models" for extracting meaning from text.
The Knowledge Vault from Google was designed to deal with facts by automatically aggregating and combining material from all over the Internet into a knowledge base that is capable of answering direct inquiries, such as "Where was Madonna born?" It was said to be distinct from the Knowledge Graph in that it automatically collected information rather than depending on crowd-sourced data created by individuals. This was one of the claims made about it.
