Google Knowledge Cards Show What Entity a Search Result is About
The Google patent “Providing Knowledge Panels With Search Results” refers to an earlier Google patent describing Knowledge Cards in depth. The patent provision is titled “Apparatus and Method for Supplying Search Results with a knowledge Card,” It is identified as being Patent Application No. 61/515,305, filed on Aug. 4, 2011.
This provisional patent about knowledge cards is not linked on the Web; otherwise, I would link to it.
It is “incorporated fully” into that later patent filing, but many details about what knowledge cards are have been left out of the later patent filing. I wrote about that patent in a post titled, How Google Decides What to Know in Knowledge Graph Results, but the patent specifically about Google knowledge cards contains information not in the later patent, which is why I created this post.
Knowledge Panel results are part of Google’s Semantic Web search results, including a mix of result types such as Direct Answers, Structured Snippets, Rich Snippets, and are part of an evolution of search results happening at Google and Bing/Microsoft that go much beyond yesterday’s 10-Blue links. I’ll be following this post with one about the rich search results that show up in response to queries at Bing.
The Google Knowledge Cards patent tells us that, “This invention generally relates to user interfaces for presenting search results.”
Search results tend to require a searcher to review several snippets of information “for different links and/or clicking through to several websites.”
Google Knowledge Cards are about the entities in sets of search results; the purpose behind this patent involving knowledge cards is to provide a factual response to a query showing different aspects related to a “single conceptual entity.” Interestingly, Google uses a Card type interface that seems to be more geared toward mobile search results than desktop results like Google Now Cards are.
Query Answers that provide knowledge cards are different than a Direct Answers to a natural language question because They focus upon providing information about a specific entity. Rather than an answer to a particular question.
What is contained in knowledge cards?
The provisional patent tells us that it is comprised of “condensed factual information that is frequently sought by a user in association with a given query.” The factual information in knowledge cards relates to different aspects of that single conceptual entity associated with a query. Knowledge cards may contain the following components:
- facts and
- related searches
For example, a knowledge card for Abraham Lincoln contains his height because he was the tallest US President, and many people query his height.
The Knowledge Cards provisional patent tells us that:
“The name is the most canonical descriptor of an entity. The name will usually be an alias for the entity that is mentioned most often as a title.” And it says that the name of an entity might be different than the name in a query. So the name will often be different than the name in a query and provides an example of the query “Leonardo vinic,” producing a knowledge card for “Leonardo da Vinci.” In response to that query, what is shown is the choice of two different entities: one for “Leonardo da Vinci” and one for “Leonardo vinic.”
The patent tells us that Knowledge cards shouldn’t be distracting to searchers:
“The description should provide an adequate explanation of what the entity is without going into so much detail as to distract from the search results page.” For example, sources of Candidate descriptions might be chosen from “a variety of places, such as prefixes of text from trusted encyclopedia articles or top-ranking web pages.”
Images shown for a knowledge panel might be taken from a “top ranking image for that entity from the search engine.”
Facts about the entity may also be displayed in the knowledge panel. For example, for an individual, those facts may be specified as the date of birth, place of birth, date of death, place of death, and nationality. In addition, related searches may be shown looking at query log information.
How Knowledge Cards Improve search engine experiences?
There are many ways knowledge cards are intended to help searchers.
- Knowledge cards help searchers with queries directed toward learning, browsing or discovery,
- Knowledge cards supply users with basic factual information about a query
- They can help a user navigate to related content seamlessly and naturally
- Knowledge cards supply new content that may not otherwise be encountered
- Knowledge cards help users find information faster than they would by clicking through search results
- Knowledge cards provide social proof that a site has a brand around it
- Knowledge cards provide sentiment-based snippets of reviews
There are a couple of different ways that a knowledge card might be used. One of those is identifying a single conceptual entity, such as a “person, place, country, landmark, animal, historical event, organization, business or sports team.” It may also be used to “distinguish between distinct meanings associated with a query term.” For example, a query of “Phoenix” may produce a knowledge card with disambiguation information about the mythical bird and other disambiguation information about the capital city of Arizona. It may contain content that enables a searcher to choose between 2 different meanings.
Sources of Content for Knowledge Cards
The kind of content shown may depend upon the type of entity. For example, a query involving a person could include a first set of standard information such as:
- birth place
- birth date
- career highlights
A query related to a place may include a second set of standard information, such as:
In both instances, we are often told that “Preferably, the knowledge card includes information from multiple sources. In this way, the knowledge card summarizes information from disparate sources.”
Factual Entities in Knowledge Cards
When knowledge cards may contain information about factual entities, such as a person, place, country, landmark, animal, historical event, organization, business, or sports team. a User interface processor might show off the content from those Knowledge Cards in a standard manner, using pre-existing content in a templated form. This is true for different types of entities. The patent provides examples of templates for:
Company Information Queries
Software Application Queries (games)
Highly Disambiguated Queries
For that last one, the example of “California universities” is provided, where there might be many possible results. When the patent was published, its authors mention listing several choices of universities, which Google was doing a few weeks ago but is no longer doing now.

This line was very amusing to read:
“The purpose behind this patent involving knowledge cards is to provide a factual response to a query showing different aspects related to a â€œsingle conceptual entity”.”
Thanks for sharing this. It was very informative.
Google is bound to make things simpler and easier for end users and this can been seen as Google is improving results through patent acquiring and implementation. Where do you see SEO headed to as one day the organic optimization ability for search marketeers would be limited in Google SERP?
Thanks for providing such an awesome update by Google. I have seen factual results in Google earlier and was surprised about how google decides what to show. I just read “https://www.seobythesea.com/2013/05/google-knowledge-graph-results/” this post, and Your post is full of information and I love to read every new post of yours.
Great post, Bill, as usual.
Just to point out: In the case of ‘California universities’ query, Google shows a Knowledge Card about California State and a Carrusell of universities and colleges in California. Probably, it depends on the amount of entities to show for Highly Disambiguated Queries.
It looks like most people-related entity searches produce SERPs without ads; however, searches for “baltimore orioles”, “Statue of Liberty” and “Disney World”, for instance, do provide SERPs with a single ad for tickets. In those instances, Google seems to be anticipating the next step in the searcher’s process. Pretty smart. Thanks, Bill!
Hi Geoff. That is likely planned, see my post: Google Patent on Ads with Named Entities, that combination of a single entity and an action associated with it in the knowledge panel.
I saw the carousel being returned for that query, and decided that I didn’t want to go into describing how Google was using carousels as lists of things like that – I’m glad you mentioned it. Like I said, the first time I performed that searhc, i got a number of schools to choose from in the knowledge panel – I’m glad that Google changed the format to showing eh list in the carousel. for those highly disambiguated queries.
Thank you Lalit – happy to hear that you are enjoying the posts so much -I want to find our everything I can, which is part of why I dig through Google’s patents.
In Google’s 10K Financial Statement for 2014 (pdf), they admitted that direct answers suited searchers better than providing them a list of links to web pages for searchers to search through. What this tells me is that if a website is built upon providing public domain type information or really generalized infomation, (What’s my IP Address? What’s the weather like today?) Google may just answer questions like those then show searchers a link to a page that does.
The provisional patent paper was filled with generalized information – it was fairly broad, and quite possibly couldn’t have stood up to a patent examiner’s prosecution as patentable Intellectual property – I think knowing that information to someone trying to study it, was useful, which is why I decided to write a post about it.
great post, now I know those things. thanks for sharing this.
google are always changing. makes it hard to keep up. nice write up
I am seeing monetised knowledge cads come up for a lot of queries, even some that are only very vaguely related to a song e.g. a lyric etc…
this knowledge card is seeming very helpful card i liked to hear this thanks for sharing this informative information keep posting like that.
This some more info on googles knowledge cards
Explore your search
With a carousel at the top of the results page, you can get a more complete picture of what youâ€™re curious about. Information from the Knowledge Graph is available on desktop, tablet, and your smartphone. So wherever you search on Google, youâ€™ll find that answers and discovery are at your fingertips.
Thank you Shiva. Very true that is about carousels and about different types of queries
Well after reading this complete blog post, I will just say It’s awesome. I really like the way of explanation in this article. Tips are very good and helpful for me. I think other people should also read blog post very seriously because this will help them to learn something new which they need. Hope this post will also help others when they will read it. Thanks for sharing this wonderful blog post.
Thanks for your nice post about Google knowledge cards.
thanks for sharing this awesome post about google updates. everyone need to know about this.
Google is always changing and its difficult to keep up with all the changes. Didnt know about this. Thanks
You’re welcome, Andrew. As far as I could tell, this information wasn’t available for anyone publicly.
Nice post Bill.I an see your every post. Thanks for shearing awesome Googleâ€™s Knowledge Cards post.
This whole emerging concept of semantic entities is really going to improve the web as a whole. Hope to see it keep moving in the right direction.
this is my 3 article that i m reading and i can say that i m in love with this blog to much helpfull too much active and informative
