The Knowledge Graph is the knowledge base used by Google and its services to improve search engine results with information collected from various sources. The information is presented to users in the infobox next to the search results. Infobox Graph Knowledge is added to Google search engine in May 2012, starting in the United States, with international expansion by the end of the year. The Knowledge Graph is supported in part by Freebase. The information covered by the Knowledge Graph grows significantly after launch, tripling in its original size in seven months, and capable of answering "about one-third" of the 100 billion Google-processed monthly searches in May 2016. This information is often used in response spoken in Google Now and Google Home search. The Knowledge Graph has been criticized for providing answers without source attribution.

Histori

Google announced the Knowledge Graph on May 16, 2012, as a way to significantly increase the value of information returned by Google search. Originally available in English only, the Knowledge Graph expanded to Spain, France, Germany, Portugal, Japan, Russia and Italy in December 2012. Recently added Bengali support in March 2017.

In August 2014, New Scientist reported that Google had launched Knowledge Vault , a new initiative to succeed Graphic Knowledge skills. Contrary to database-related numbers, Knowledge Vault is meant to handle facts, collect and merge information automatically from across the Internet into a knowledge base capable of answering direct questions, such as "Where Madonna was born". It has been reported that its main function on the Knowledge Graph is its ability to collect information automatically rather than relying on crowdsourced facts compiled by humans, having collected over 1.6 billion facts at the time of the 2014 report; 271 million of these facts are considered "convincing facts", a term for information that is considered to have more than 90% chance of becoming a reality. However, after publication, Google contacts the Land Search Engine to explain that Knowledge Vault is a research paper, not an active Google service, and in its report, the Land Search Engine is an indication referenced by the company that "many models" are being experimented with to test the possibility of collecting meaning from the text automatically.

Description

Information from the Knowledge Graph is presented as a box to the right or top of the search results phone. According to Google, this information is derived from many sources, including CIA World Factbook , Wikidata, and Wikipedia. Knowledge base is growing rapidly in size, tripling its original size within seven months after it was announced to the public, covering 570 million entities and 18 billion facts. In October 2016, Google announced that the Knowledge Graph has over 70 billion facts. There is no official documentation of the technology used for the application of the Knowledge Graph.

Information from the Knowledge Graph is used to answer live spoken questions in Google Now and Google Home voice queries.

Criticism

Lack of source attribution

As of May 2016, the knowledge box appears to "roughly one-third" of the approximately 100 billion monthly searches that the company processes. Dario Taraborelli, head of research at the Wikimedia Foundation, told The Washington Post that Google's omission from sources in his knowledge box "undermines people's ability to verify information and, ultimately, to develop well-informed opinions". The publication also reported that the boxes were "often unassigned," such as a box of knowledge about the age of actress Betty White, who "lacks the resources and absolute as if descended from God".

Reject Wikipedia article, readout

According to the The Register , implementing direct answers in Google search results has led to a significant decline in readership for the online encyclopedia Wikipedia, from which the Knowledge Graph obtains some of its information. The Daily Dot notes that "Wikipedia still has no real contenders as far as the actual content is concerned.All the contested is traffic statistics And as a nonprofit, traffic numbers do not equate to income in the same way they do to commercial media sites ". After the publication of the article, a Wikimedia Foundation spokesperson, who has Wikipedia, reached out to state that "welcomed" the Graphical Knowledge function, that it "looked into" traffic down, and that "We also did not notice significant drops in search engine referrals. We also have ongoing dialogue with staff from Google working in the Knowledge Panel ".
