Use-cases and Scenarios for Developing Knowledge-Based Systems

The development of knowledge-based systems requires the availability of domain and problem-solving knowledge. This knowledge must be acquired from domain experts. For this purpose the paper proposes to adopt the concept of scenarios known from requirements engineering and object oriented modelling to enrich the set of acquisition techniques. In RE and OO scenarios are used to define a vision of a future system. In knowledge engineering their scope has to be extended, but their advantages (ease of understanding, support of communication, focus on relevant aspects etc.) still hold for knowledge-based systems.
