Abstract: A method, apparatus, system, and computer program product provide an affinity between a first entity and a second entity on a social network. First affinity data for a first entity is determined. The first affinity data is first behavioral data and first categorical data. Second affinity data for the second entity is determined. The second affinity data is second behavioral data and second categorical data. The first affinity data is compared to the second affinity data resulting in an affinity score. The affinity score identifies a probability of similar interests between the first entity and the second entity based on behavioral similarities between the first behavioral data and the second behavioral data, and categorical similarities between the first categorical data and the second categorical data. The affinity score is then provided to the first entity.
