In NKRL, templates take the form of combinations of quadruples connecting together the ‘symbolic name’ of the template, a ‘predicate’ – as BEHAVE, MOVE, OWN, PRODUCE… – and the ‘arguments’ of the predicate (concepts or combinations of concepts) introduced by named relations, the ‘roles’ (like SUBJ(ect), OBJ(ect), SOURCE, BEN(e)F(iciary), etc.). The quadruples have in common the ‘name’ and ‘predicate’ components. If we denote then with Li the generic symbolic label identifying a given template, with Pj the predicate used in the template, with Rk the generic role and with ak the corresponding argument, the NKRL core data structure for templates has the following general format (Li (Pj (R1 a1) (R2 a2) … (Rn an))). Templates are included in an inheritance hierarchy, HTemp(lates), which implements NKRL’s ‘ontology of events’.

Abstract
In this paper, we evoke first the ubiquity and the importance of the so-called ‘non-fictional narrative’ information, with a particular emphasis on the terrorism- and crime-related data. We show that the usual knowledge representation and ‘ontological’ techniques have difficulties in finding complete solutions for representing and using this type of information. We supply then some details about NKRL, a representation and inferencing environment especially created for an ‘intelligent’ exploitation of narrative information. This description will be integrated with concrete examples to illustrate the use of this conceptual tool in a terrorism context.
