Abstract

This paper presents a technology for information portals that supports multimedia retrieval while focusing at the same time on different ecologies of information provider and content owner environments. This means it addresses cross-media information provision and cross-owner content building. The technology was developed under the FP5 project IRAIA 1 and was applied to two different areas: economic information and cultural information related to puppetry 2. The first area puts more emphasis on multimedia retrieval while the latter one has special requirements in respect to cross-owner content building and content delivery. IRAIA enriches the implementation of multimedia, cross-media, and cross content owner retrieval with a design flexibility that enables an information provider to adapt the delivery channel as well as the content building process to requirements specific to its service. Leading through IRAIA applications in the areas mentioned above we present IRAIA’s system design and architecture, its human-computer interaction modes, and its powerful semantic layer that links the different facets of cross-media delivery and of cross-content building. Context-aware computing, cross-media information provision, cross-owner content building, intecreation. 1 The project IRAIA (IST-1999-10602) was co-funded by the European Commission under the 5th framework programme.
