Abstract: A system and method for generating and publishing inferential newsfeeds captures actively and passively provided user data elements which are processed into user facts. A Cache Management Module maintains updated cached copies of rules and execution plans. The cached copies of rules and execution plans are applied to the user facts, to inferentially generate newsfeed posts. An Inferential Data Mining Module runs each execution plan in a multi-threaded process for each user, and processes each rule within the context of the execution plan to generate the newsfeed posts. A Newsfeed Generation Module applies newsfeed templates to format the newsfeeds for various platforms. The Inferential Data Mining Module mines the Data Store for a determination of which user facts should be used to create the newsfeed posts, and of which users should be designated as subscribers to the newsfeed posts, said determination taking place independently of individual users' direct actions.
