We propose a method of content-based multimedia retrieval of objects with visual, aural and textual properties. In our method, train- ing examples of objects belonging to a specific semantic class are associ- ated with their low-level visual descriptors (such as MPEG-7) and textual features such as frequencies of significant keywords. A fuzzy mapping of a semantic class in the training set to a class of similar objects in the test set is created by using Self-Organizing Maps (SOMs) trained from automatically extracted low-level descriptors. We have performed sev- eral experiments with different textual features to evaluate the potential of our approach in bridging the gap from visual features to semantic concepts by the use textual presentations. Our initial results show a promising increase in retrieval performance.
