Abstract: The system relates to a system and apparatus for a scalable engineering system deployed in production that mines topical interests from multiple social networks and assigns over tens of thousands of topics to hundreds of millions of users on a daily basis. The system extracts and analyzes features for topic inference that extend beyond authored text. The system uses a diverse set of features and cross network information can lead to a better understanding of a user's interests. This system focuses on assigning topics for a user that other users can socially recognize and acknowledge.

Abstract: The techniques, methods and systems described herein facilitate the automated discovery and presentation of content created, published or otherwise made public by “experts” and key influencers on particular topics. As such, users that may be interested in particular topics but may not know who to connect with in order to receive the most pertinent information can receive highly-relevant information. Embodiments of the invention use topics of interest identified by the user and/or automatically identifies topics based on previous postings, communication, contacts, etc. Individuals, companies, organizations and other entities that have been recognized as highly influential in those topics are identified and, without explicit actions by the user, adds content generated by the influential entities to the user's content data feed.
