We track where Google is getting the Knowledge Panel attributes from. Although Google corroborates the information it shows on multiple authoritative, trustworthy third party sources, we can identify what the initial source is - incredibly valuable information for anyone wanting to ensure the accuracy of the information Google shows about their Entity (brand, person, film, product…)
The actual root sources for these attributes is no longer a mystery: the distinction between the sources Google is using is clear to us at Kalicube.
What Sources Does Google Use for Knowledge Panel Attributes?
The titles of the sources are ours, not Google's. But the distinction between them is 100% clear.
3rd Party sources – curated by humans such as Wikipedia and Wikidata.
Google sources – curated by humans through Google products such as Google Business and Google Podcasts.
WebFacts – deduced by Google’s Knowledge Graph algorithms from the information taken from a seed set of trusted sources.
WebFacts 2nd Gen. – deduced by Google’s Knowledge Graph algorithms from the information in Google’s web index. This is the key to the future of Knowledge Panel management that we are aiming to master at Kalicube SAS.
