A reintroduction to our Knowledge Graph and knowledge panelsA reintroduction to our Knowledge Graph and knowledge panelsPublic Liaison for Search
Our systems aim to show the most relevant and popular information for a topic within a knowledge panel. Because no topic is the same, exactly what is shown in a knowledge panel will vary. But typically, they’ll include:
- Title and short summary of the topic
- A longer description of the subject
- A picture or pictures of the person, place or thing
- Key facts, such as when a notable figure was born or where something is located
- Links to social profiles and official websites
Knowledge panels might also include special information related to particular topics. For example:
- Songs from musical artists
- Upcoming episodes from TV shows
- Rosters of sports teams.
Sources of information for the Knowledge Graph
The information about an “entity”—a person, place or thing—in our knowledge panels comes from our Knowledge Graph, which was launched in 2012. It’s a system that understands facts and information about entities from materials shared across the web, as well as from open source and licensed databases. It has amassed over 500 billion facts about five billion entities.
Wikipedia is a commonly-cited source, but it’s not the only one. We draw from hundreds of sources from across the web, including licensing data that appears in knowledge panels for music, sports and TV. We work with medical providers to create carefully vetted content for knowledge panels for health issues. We also draw from special coding that content owners can use, such as to indicate upcoming events.
On mobile, multiple knowledge panels provide facts
When we first launched knowledge panels, most search activity happened on desktop, where there was room to easily show knowledge panels alongside search results. Today, most search activity happens on mobile, where screen size doesn’t allow for a side-by-side display.
To this end, information from the Knowledge Graph is often not presented through a single knowledge panel on mobile. Instead, one or more knowledge panels may appear interspersed among the overall results.
