Aside from interest, other things influence a consumer's desire to interact with content or make a purchase, but it all points back to the mood of the individual. An Apple patent describes a method to analyze the data behind a person's mood associated with specific characteristics over time. The technology infers the user's mood by applying rules to compare their current mood-associated data to at least one baseline mood profile for the user. A little geeky -- but it brings behavioral data into more than one type of ad or content targeting.
