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.

The method as claimed in claim 8 , wherein a monitoring module, on the basis of the variable mood variable, triggers following a determinable event, the triggering occurring independence on the time variation of the mood variable.
