|Administering the Community / Understanding the Jive Genius Recommender Service|
The Recommender Service obeys all content permissions and will not recommend content that a user doesn't have permission to view. Therefore, users may not see the same Trending Content or Trending People, depending on their content viewing permissions, when they logged in, and when the last Recommender content poll occurred. Recommended for You is dynamic. Its recommendations change based on a user's shifting interests and affinities. The Recommender will even respond to changes in the org chart.
To understand the architecture of the Recommender Service and its relationship to the Activity Engine, refer to the drawing in What is the Activity Engine?
The Recommender analyzes content and people over a period of time and uses that data to display the Trending People and Trending Content in the system. The Recommender counts the things users do (create content, follow people, join groups, etc.) and, importantly, how users interact with each other's contributions. For example, users liking another user's content, marking answers helpful or correct, and viewing content all count toward the trending status of a user or a piece of content. The Recommender weights the various counts in its equations, and then creates a list of users and content with the highest trending counts over a given time period. Trending People recognizes and rewards users who are a positive influence on the community.These widgets are updated every 15 minutes and display 10 entries by default. These settings are not configurable.
Trending Content and Trending People are based on global algorithms; they are not user-specific. However, users may not see the same trending people or content based on their viewing permissions. For example, if a user does not have permission to see trending content items 1-10, they will instead see items 11-20 if they have the correct viewing permissions for those items. The Trending People will often be the same for all community users, but it can be different depending on when users logged in and when the last Recommender content poll occurred. In addition, a person may be trending because of something they are doing in a secret group. In that case, you would not be able to see why the person is trending by looking at their recent activity.
The number of Likes displayed on a discussion listed in Trending Content is the total number of Likes on that discussion plus the total number of Likes of all the replies to the discussion.
