Abstract
The visibility of shared documents in a collaborative recommender system is managed by analyzing both the document's substance and user actions that are performed on the document. The document's substance includes both metadata and content. User actions include both user ratings and semantic actions. The visibility of the shared documents is updated when either a user action or an event occurs.
