10. The method of claim 1 wherein the step of determining resource transition probabilities based on the identification of users, the identification of resources, and the defined sessions includes sub-steps of: i) counting a number of different sessions in which a first resource was referenced to generate a first count; ii) counting a number of different sessions in which a second resource was referenced after the first resource was referenced, to generate a second count; and iii) determining a transition probability from the first resource to the second resource based on the first and second counts.
