SYSTEM AND METHOD FOR USER-CONTROLLED, MULTI-DIMENSIONAL NAVIGATION AND/OR SUBJECT-BASED AGGREGATION AND/OR MONITORING OF MULTIMEDIA DATA

A system and method for user-controlled multi-dimensional navigation and/or subject-based aggregation of multimedia data, a multiplicity of node elements being generated and a node element including one or more search terms and/or weighting terms that can be logically combined. For each multimedia data element to be registered, a relevance index parameter is determined for each paired combination of node elements and allocated to the respective pair of node elements. In dependence on the relevance index parameters, one- or multi-dimensional distance factors are determined. Based on the registered multimedia data elements and/or node elements, a topological navigation map is generated and graphically displayed in dependence on the respective one- or multi-dimensional distance factors so that the user can navigate in the topological navigation map by an input device and can access required multimedia data elements and/or node elements.
