The data sorting or recognition system of Specification 1,034,814 is modified by the provision of means for recording in the store a plurality of separate sets of information signals and for comparing an input information signal with the first information of each set and with other information signals of sets selected by the result of previous comparisons with information signals in the same set. The input information signal is sorted by this procedure and the arrangement is such that the number of comparisons involved in each sorting tends to be the same in every case. A response signal is recorded with each information signal in the store and the response signal corresponding to the information signal most closely matching the input information signal is selected as the recognition output.
