In this paper we present our work on requirements elicitation. The elicitation process is a complex task which necessitates computer support. Elicitation systems should ideally help their users check the correctness of the specifications obtained but also actively guide them in the acquisition of the requirements. We consider hereafter systems that communicate in natural language. We describe a...

Informationen über den jeweiligen Kontext, in dem Nutzeranforderungen an ein interaktives System entstehen, verhelfen nicht nur zu einem besseren Verständnis des Anforderungsinhalts, sondern unterstützen auch den strukturierten Zugriff, die Exploration und Analyse von großen Anforderungsmengen. Dieser Beitrag beschreibt einen Ansatz zur kontextsensitiven Erfassung von Nutzeranforderungen. Es we...

This paper presents an extended version of goal-oriented analysis methods where an idea generation method is combined to reinforce the support of the step for identifying subgoals by a team of stakeholders. To assess our method, experimental results are also discussed.

This paper deals with preference representation and elicitation in the context of multiattribute utility theory under risk. Assuming the decision maker behaves according to the EU model, we investigate the elicitation of generalized additively decomposable utility functions on a product set (GAI-decomposable utilities). We propose a general elicitation procedure based on a new graphical model c...
