Dynamic Reconfiguration of Multimodal Architectures

H. Djenidi, A. Ramdane-Cherif, N. Levy, C. Tadj

The multimodal architectures should react to events occurring simultaneously, and possibly redundantly, from different input media. In this paper, intelligent expert agent-based architecture for multimedia multimodal dialog protocols is proposed. The generic components of the multimodal architecture are monitored by an expert agent, which can perform dynamic changes in reconfiguration, adaptation and evolution at the architectural level. Software performance and usability are maintained by the expert agent via a scenario-based methodology. The expert agentís behavior modeled by Petri nets permits a software quality tradeoff between attributes of usability and other software attributes like systemís performance.

Keywords: multimodal architecture, dynamic reconfiguration, multi agents systems.
