Hope you enjoyed the lunch (I also had a dinner). So, I roughly describe now my usecase: automatic audiovisual content annotation. Several organisations like digital libraries, museums, companies, archives but also personal users have digital audiovisual content that need to be annotated in order to be easily accessed. This is, in general, a time-consuming and costly process, so automatic (or semi-automatic) systems for this aim are in the main focus of the research in the area of image, video and audio processing and analysis. Lately, the proposed techniques focus in knowledge-based analysis and the need for rules is obvious in several steps like object and event recognition, alignment of different multimedia ontologies (for example two different domain ontologies that have some same concepts) etc. Of course in the above cases, we need both a rule language (there are many) and a rule interchange format between different systems (if I understand correctly the terminology). The most important thing is that we need efficient tools, since the process of recognition is really complicated and the data sources contain really huge data. Thus, it is necessary to start from a quite restrictive core rule language and then extend it. On the other hand, it is also important that in order for the automatic analysis tools to be realistic there is need for more sophisticated characteristics like uncertainty handling, context-based reasoning, temporal reasoning, etc. Thus, we need to keep this language ready to be extended for covering these issues. Regards, Giorgos
