N.: A Framework to Integrate Ubiquitous Knowledge Modeling, (to appear

This paper describes our contribution to let end users configure mixed-initiative spoken dialogue systems to suit their personalized goals. The main problem that we want to address is the reconfiguration of spoken language dialogue systems to deal with generic plug and play artifacts. Such reconfiguration can be seen as a portability problem and is a critical research issue. In order to solve this problem we describe a hybrid approach to design ubiquitous domain models that allows the dialogue system to perform recognition of available tasks on the fly. Our approach considers two kinds of domain knowledge: the global knowledge and the local knowledge. The global knowledge, that is modeled using a top-down approach, is associated at design time with the dialogue system itself. The local knowledge, that is modeled using a bottom-up approach, is defined with each one of the artifacts. When an artifact is activated or deactivated, a bilateral process, supported by a broker, updates the domain knowledge considering the artifact local knowledge. We assume that everyday artifacts are augmented with computational capabilities and semantic descriptions supported by their own knowledge model. A case study focusing a microwave oven is depicted. 1
