What is the logic behind the recommendations in the Daily Digest?

Description: 

I would like to know what the logic is for the recommendations in the Daily Digest.  How does Degreed decide what to include?

Answer:

The Daily Digest uses algorithms that match the Home page of the user, which is based on Skills, trends in the organization, and external content that many internal users are completing. Additionally, the Daily Digest includes an overview of stats, items completed, items shared with the user, points earned, new followers, learning recommendations, Degreed activity, and recent shares with the user.
