DOMIR - Diálogos e Ontologias para Recuperação de Informação Multimédia

The manipulation of large quantities of information, once a task for specialists, is currently required of people in all areas, not only in their professional life but in most of everyday. The notion of document is however changing, as multimedia documents are commonly created by ordinary applications and audiovisual information needs to be managed. The retrieval system must be able to process documents and create descriptions that can relate these items, using words, underlying ontologies and the analysis of audio and visual items. To go beyond text retrieval, the analysis of document components such as audio or image segments is required. Ontologies will be used at this point: both the inclusion of audiovisual descriptors in ontologies and their combination with domain ontologies will be explored. The retrieval task can also be significantly improved by gathering information from the user interaction and analyzing the dialog to extract user intentions and plans.
