Abstract
An analysis system analyzes known user affinities to identify particular objects that serve as useful predictors of whether a given user will have an affinity for a given topic, even if the user has not previously expressly specified an affinity for that topic. Specifically, both the topic group of users associated with a given topic and the category group of users associated with the topic's more general category are identified. For each of a set of objects, degrees of divergence between the topic group and the category group are evaluated for a criterion evaluated with respect to the object. A topic profile is created based on objects for which there is a high degree of divergence.
