VISITOR PROFILE MODELING

Methods, systems and computer program products for inferring a value of a visitor property for a visitor to a web destination are described. A set of traversals indicating visits to web destinations are received, including scored and unscored traversals. Initial destination scores for the web destinations visited by the scored traversals are inferred based on the known scores of the scored traversals. Initial scores for the unscored traversals are estimated based on the initial destinations scores. Revised destination scores for the web destinations visited by the scored traversals and initial destination scores for the web destinations only visited by the unscored traversals are inferred. Revised scores for the unscored traversals are estimated based on the revised destination scores and initial destination scores. Revised destination scores for all of the web destinations are inferred based on the scores of the scored traversals and the revised scores of the unscored traversals.
