A data processing system for dynamically computing weighted relations between data representing information in at least one data inventory, in which data processing system means are provided which are configured and/or adapted such that an relation as link between at least one data item representing at least one information of at least one data inventory and at least one other data item representing at least one information of at least one data inventory will also be gathered as a data item representing an information, wherein the relations will be automatically determined and kept updated by the data processing system, and wherein the relations will by dynamically determined as n-to-n links, wherein n is a natural integer, wherein the link will be generated by means of a syntactic comparison of the data representing the information of an relation request and the data representing the information of the at least one data inventory, wherein the syntactic comparison is carried out on the base of describable rules by calling keys in the sense of attributes which describe which information modules and data types shall be used for retrieving relations, wherein the data processing system comprises an analyser component which is configured for composing a filter from the rules, which filter is appropriate to search the data representing the information of the at least one data inventory for matching character strings of those keys which correspond to the data representing information of the relation request. at least one data item representing at least one information of at least one data inventory and at least one other data item representing at least one information of at least one data inventory the relations will be automatically determined and kept updated by the data processing system, the relations will by dynamically determined as n-to-n links, wherein n is a natural integer, of the data representing the information of an relation request and the data representing the information of the at least one data inventory, wherein the syntactic comparison is carried out on the base of describable rules by calling keys in the sense of attributes which describe which information modules and data types shall be used for retrieving relations, wherein the data processing system comprises an analyser component which is configured for composing a filter from the rules, which filter is appropriate to search the data representing the information of the at least one data inventory for matching character strings of those keys which correspond to the data representing information of the relation request. the syntactic comparison is carried out on the base of describable rules by calling keys in the sense of attributes which describe which information modules and data types shall be used for retrieving relations, the data processing system comprises an analyser component which is configured for composing a filter from the rules, which filter is appropriate to search the data representing the information of the at least one data inventory for matching character strings of those keys which correspond to the data representing information of the relation request. <EOS>
