ABSTRACT:
Disclosed are a document retrieval method and system for separately performing a process for correcting erroneously recognized characters existing in characteristic character strings within a seed document or the documents to be registered and a process for tolerating erroneously recognized characters existing in the documents targeted for retrieval. The process for correcting erroneously recognized characters existing in characteristic character strings extracts characteristic character strings from a read document, replaces the extracted characteristic character strings containing erroneously recognized characters with character strings appropriate for document retrieval, and selects characteristic character strings for use in actual document retrieval.
