Image data information systems require both database and visual capabilities but there is a gap between these systems. Database systems usually do not deal with multidimensional pictorial structures and vision systems do not provide database query functions. In terms of these points the evaluation of content-based image retrieval systems became a focus of research interest. One can find several system evaluation approaches in literature however only few of them go beyond precision-recall graphs and do not allow a detailed evaluation of an interactive image retrieval system. Apart from the existing evaluation methodologies we aim at the overall validation of our knowledge-driven content-based image information mining system. In this paper an evaluation approach is demonstrated that is based on information-theoretic quantities to determine the information flow between system levels of different semantic abstraction and to analyze human-computer interactions. Keywords and phrases image information mining CBIR evaluation information theory human-computer interaction. 1. INTRODUCTION In recent years the growth of data collected and stored in archives and the access via the .
