Abstract: Information delivery system and methods detects and organizes information into canonical topics, such as who, what, when, where, price, etc., and facilitates a user to persistently subscribe to topics, web users, web resources, event streams, etc. The system facilitates a user to register devices and applications on which to receive information, as it becomes available, related to the subscription(s). The system facilitates users to specify preferences for the topics, web users, web resources, and registrations, which prioritize delivery of information. The system senses information, aggregates the user's registrations, subscriptions, and preferences, and filters information a topic-interest basis. The system notifies a user based on the preferences.
