1. A method for user controlled multi-dimensional navigation of multimedia data, comprising: generating or extracting a multiplicity of node elements out of multimedia data to be registered, a node element comprising one or more extracted search terms, generated search terms or weighting terms that can be logically combined; determining a relevance index parameter for each multimedia data element to be registered for each paired combination of node elements and that is allocated to the respective pair of node elements; determining, in dependence on the relevance index parameters, one- or multi-dimensional distance factors, the absolute value of the corresponding distance factor becoming smaller with increasing relevance of two paired multimedia data elements with respect to one another; generating and graphically displaying, on the basis of at least one of the registered multimedia data elements or node elements, a topological navigation map in dependence on the respective one- or multi-dimensional distance factors; and wherein the topological navigation map is navigable through use of an input device to permit user access to at least one of desired multimedia data elements and node elements, wherein following user-specific selection of at least one of an initiating node element and multimedia data element and produced clusters of node elements and multimedia data elements, the topological navigation map is corrected in a perspective of at least three-dimensions with respect to at least one of the initiating node element and multimedia data element and clusters, and displayed accessible to the user, the topological navigation map displays a dynamic and moveable at least three-dimensional perspective for user navigation therethrough in order to respond in real-time by displaying changes in the distance factors of the relevance index parameters indicative of changes in said relevance of two paired multimedia data elements with respect to one another.
8. The method as claimed in claim 1 , wherein one or more search terms, which can be logically combined, are stored in a data memory, a computing unit accesses network nodes connected to source databases via a network, and data of the source databases are selected on the basis of the search terms, in a data memory, at least one weighting parameter is stored and allocated to a search term or a logical combination of search terms, wherein by a filter module of the computing unit, a multiplicity of source databases of the network nodes are accessed and a weighting list with found data records is generated for each weighting parameter in conjunction with the associated search terms, at least one or more of a source database type or a time information of the occurrence of the documents in this source database or location information of the source database is stored and allocated to each of the data records found, and wherein, by a parameterizing module, one or more variable mood variables are generated at least partially dynamically on the basis of at least one or more of the weighting list, the associated source database types or the time information or location information for the respective weighting parameter, which variable mood variables correspond to temporal mood fluctuations of users of the network, the generated search terms or node elements comprising at least the mood variables.
