Managing evidential reasoning for identity information fusion

A case study in which the Dempster-Shafer evidential reasoning theory is applied to a naval identity and attribute fusion problem is described. Two identity information fusion architectures are discussed: the first concerns the fusion of identity declarations where the sources are expected to provide only useful and complete results such as an identity declaration, and the second architecture addresses the fusion of incomplete attribute information coming from various sources. The emphasis is put on the second architecture. The use of fuzzy logic for proposition generation is described as well as techniques for managing the number of propositions generated.
