Google’s search results sometimes show information that comes from our Knowledge Graph, our database of billions of facts about people, places, and things. The Knowledge Graph allows us to answer factual questions such as “How tall is the Eiffel Tower?” or “Where were the 2016 Summer Olympics held.” Our goal with the Knowledge Graph is for our systems to discover and surface publicly known, factual information when it’s determined to be useful.
Where do Knowledge Graph facts come from?
Facts in the Knowledge Graph come from a variety of sources that compile factual information. In addition to public sources, we license data to provide information such as sports scores, stock prices, and weather forecasts. We also receive factual information directly from content owners in various ways, including from those who suggest changes to knowledge panels they’ve claimed.
How does Google correct or remove Knowledge Graph information?
Google processes billions of searches per day. Automation is the only way to handle this many searches. This means the best way to improve our results is to improve our automated systems, our search algorithms.
Our systems automatically strive not to show information that would violate our policies listed below. However, the scale of search is so large that no system can be perfect. This is why we provide public reporting systems.
We carefully analyze the data captured through our public reporting systems and work to remove content that violates our policies. This data is also used to inform improvements to our algorithms. We also manually remove policy-violating information that comes to our attention, especially prioritizing issues relating to public interest topics such as civic, medical, scientific, and historical issues or where there’s a risk of serious and immediate harm.
How to request a knowledge panel change or report a Knowledge Graph issue
Knowledge Graph information about people, places, or things is often presented within knowledge panels.
If you’re the subject or an official representative of an entity depicted in a knowledge panel, you can claim this panel and suggest changes. More information about these processes are available in the following articles:
Businesses have special Business Profile panels and should use Business Profile to create, claim, and make suggestions to those.
Beyond official entities, anyone can send feedback about issues with knowledge panels, Business Profiles, or Knowledge Graph information in general. Such displays have feedback options.
- On desktop, select Feedback at the bottom of displays to send feedback.
- On mobile, select Feedback at the bottom of displays, or use the three vertical dots menu option at the top, to send feedback.
