Abstract
The electronic dictionary disclosed herein is organized for expeditious search based on partial spelling by assigning words to blocks having a predetermined maximum size, the blocks being represented by respective partial spelling sequencer. The words are assigned to blocks by progressing through successive possible sequences in order and, for each sequence, determining the number of words in the set of words corresponding to that sequence. If the number of words is less than the maximum, all of the words in the set are assigned to a corresponding terminal block. Otherwise words up to a preselected number are assigned to a non-terminal block and the partial spelling sequence is extended. As a result of the organization only one call to the dictionary needs to be made for each extension of the sequence.
