Facebook's semantic heart is the Social Graph . This is where the news feed algorithm is supplied with relationship information in order to deliver the hopefully most relevant news from the social environment in the respective user's feed. The intensity of interaction between users plays an important role here.
Amazon has also left the delivery of information to a complex algorithm that uses relationship structures to create context.
All of these systems are about representing relationships between entities or people, topics, terms, documents, user-related information... With the aim of putting a search query or a current situation into context, for example, and assigning relevance to information, offers, documents... accordingly. Only those who provide relevant information according to the context will remain interesting as gatekeepers.

"Relevance is a term for the significance or importance that someone attributes to something in a certain context.

The semantic web is designed to categorize and contextualize the large amount of data and information.
