PURPOSE:To prevent busy state on the way of retrieval and to improve retrieving speed by dispersing storage information with high similarity into a storage space to store it in an information retrieving method by a matching test using storage and input information. CONSTITUTION:A characteristic vector obtained by decomposing a character to stroke and extracting from a reading character pattern is set up in a register 16. While counting up a counter 12 by a signal 18, a comparator 14 reads out dictionary feature vector successively from the leading address of a memory 10, discriminates rough matching at a [ I ] part, and when the matching is obtained, starts precise matching at a [II] part and continues the test also at the part [ I ]. If the matching is obtained by the [ I ] part before the completion of the test at the [II] part, busy state is generated. Therefore, the generation of the budy state is prevented by storing the dictionary feature vector with high similarity in separated addresses of the memory 10. |
