What are Vertical Knowledge Graphs?
Google has multiple Vertical Knowledge Graphs. Many people think only of the Main Knowledge Graph (which at Kalicube we also call the Knowledge Vault). There are, however, multiple Vertical Knowledge Graphs including Google Podcasts, Google Maps, Google Books, Google Scholar.
At Kalicube we have identified these distinct ways:
- Google Books and Google Scholar are human curated,
- Google Podcasts is human curated in that it takes information from publicly available podcast feeds,
- Google Maps is partially human curated by businesses, and by Google employees, with additional information added using Machine Learning algorithms.
- The Web Index Knowledge Graph is built from information in Google’s Web Index using Machine Learning.
Using Kalicube’s three step process, getting an Entity into the Web Index Knowledge Graph is relatively simple. From there, getting it into the Knowledge Vault is a question of keeping the Entity Home up to date, adding additional corroboration and identifying meaningful (truthful) relationships with Entities already in the KnowledgeVault.
It is only when your entity is in the Knowledge Vault that you can get this type of result (everything in yellow is the Knowledge Panel):
In the Knowledge Panel Course in the Kalicube Academy we cover how these Vertical Knowledge Graph function, and how you can use them to trigger Knowledge Panels, and also how to move the entity fomrthe verticals to the Main Knowledge Graph.
