Abstract

This paper is concerned with the part of the system dedicated to the processing of the user's designation activities for multimodal search of information. We highlight the necessity of using specific knowledge for multimodal input processing. We propose and describe knowledge modeling as well as the associated processing architecture. Knowledge modeling is concerned with the natural language and the visual context; it is adapted to the kind of application and allows several types of filtering of the inputs. Part of this knowledge is dynamically updated to take into account the interaction history. In the proposed architecture, each input modality is processed first by using the modeled knowledge, producing intermediate structures. Next a fusion of these structures allows the determination of the referent aimed at by using dynamic knowledge. The steps of this last process take into account the possible combinations of modalities as well as the clues carried by each modality (linguistic clues, gesture type). The development of this part of our system is mainly complete and tested.
