Abstract
The development of the so called intelligent multimedia presentation systems (IMMPSs) is currently very actively addressed by research groups worldwide. A common goal of the research community istodevelop mechanisms for the automated generation of multimedia presentations. Up to now, some large-sized prototypes of IMMPSs have been built and user interfaces of some applications already include automated components for certain generation tasks such as text or graphics generation. Unfortunately, there is no common agreement on a generic architecture for IMMPS with clear functional de nitions of involved subcomponents. Moreover, even the terminology used in the descriptions of existing IMMPSs varies considerably across research teams. With the proposal of a reference model for IMMPSs, this paper tries to ll a major methodological gap and thus may provide a sound basis for ongoing and future developments of IMMPSs. In essence, the proposed reference model consists of several layers referring to the particular subtasks which occur in multimedia presentation generation. Following the paradigm of knowledge-based computing, we introduce a minimum set of explicitly encoded knowledge, and assign it to some logically distinct knowledge sources. These sources allow to share knowledge among components of di erent layers in a client-server fashion. In order to demonstrate the use of the reference model, we provide a comparison of two IMMPS by redescribing them in terms of the model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
