The validation of requirements specifications by the stakeholders, i.e. the end users, still is one of the weakest steps in the software life cycle. This is mainly due to the fact that there is no standard modeling and representation method for requirements which is transparent and easy enough to be understood intui tively by the end user. Neither natural language repre sentation nor the traditional conceptual modeling language proved appropriate for that purpose. With our project NIBA1 we aim to attack this problem by introducing an "interlingua" for requirements model ing between the language of the end user and the con ceptual level. This approach is accompanied by a set of heuristics supporting an automated mapping of both, from natural language requirements specifica tions to interlingua representations, and from the latter to conceptual schemata. This paper discusses recent project results concerning the modeling and mapping of behavioral aspects of a given Universe of discourse.
