General-purpose image database management systems either define visual rele-Operational image databases are subsystems of systems which contain images, structured data, structured data complevance in terms of low level features and give the user tions, and algorithms, all relating to a particular real-world control over how features are used in the distance measure, domain. Traditional notions of image similarity therefore need e.g., , or provide comprehensive suites of relevance meato be extended to handle retrieval of mixed datatypes. In this sures each suitable for specific application areas, possibly paper, we use the structured datatypes to describe a user's with some self-learning capability [8]. In any case, different interests and background knowledge and then to ascribe a value users have different notions of relevance, so the option of to that user of the information in the system. The difference weighting components of the measure is provided, e.g., between the information values in two states of a system leads [9, 10].
