"Under this project, we studied and developed technologies to 'score' entities to build models that will produce an estimate of the likelihood that an entity exhibits some characteristic. For example, a social network may include malicious individuals. Suspicion scoring assigns a numeric value to each entity in the network, representing the estimated likelihood that the entity is malicious. We have focused on scoring entities that are interconnected in some sort of a network (e.g., a social network) and on techniques for building and using scoring models when important information is unknown, but may be acquired at a cost. This project has also produced 20 published technical papers."
