This paper covers terminography work in the FF POIROT project, a European research project in which formal and shareable knowledge repositories (i.e. ontologies) and ontology-based applications are developed for the prevention of value added tax carousel fraud in the EU and the detection of securities fraud. The authors emphasize that the knowledge requirements regarding users and applications determine what textual information should be structured at macro- and micro-levels of the FF POIROT multilingual terminology base. Furthermore, the authors present their ideas concerning a multidisciplinary approach in terminography, called ‘Termontography’, for future application-oriented terminology development.
