Abstract: A mathematical model to represent multiple role events of a threat scenario, and a methodology to score the events given the data or evidence contained in a knowledge base is provided. The multiple role event can include any action encompassed by an independent clause having multiple syntactical roles (subject, object, location, etc. . . . ) and containing multiple entities (person A, person B, object C, place D, etc. . . . ). Multiple role events are represented as elements of a tensor space, and are scored using tensor operators built from the semantic graph associated with the knowledge base.
