Abstract: Emotions are utilized as the basis for categorizing and searching content, including creating reviews, characterizing existing Internet items through automated and manual analysis, creating user profiles for behavioral targeting applications, matching consumers to items, searching for items, and recommending items. Content is first classified or characterized by emotion. A person's emotional needs are then determined. These emotional needs are then utilized to search for and provide content to that person.

Abstract: An improved inter-module communication facilitation mechanism (CFM) is disclosed, which provides improved scalability, improved efficiency, and enhanced functionality and performance. In one aspect, the CFM enables a subscriber to subscribe to multiple events using a single namespace specification and a single subscription request. In another aspect, the CFM enables publishers to broadcast, rather than unicast, events to multiple subscribers concurrently. In yet another aspect, the CFM enables message exchange between senders and recipients to be conducted reliably, while at the same time ensuring that a message will be delivered to a recipient at most once. These and other aspects give rise to the many benefits offered by the CFM.
