A METHOD OF CHARACTERISTIC CHARACTER STRING MATCHING BASED ON DISCRETENESS, CROSS AND NON-IDENTICAL

摘要

A method of characteristic character string matching based on discreteness, cross and identical, with steps of: A, user setting discreteness number, cross number and non-identical number by user interface, or information processing device automatically setting the discreteness number, cross number and non-identical number; B, for a specified text, based on the keyword input by user, the information processing device taking the discreteness number, cross number and non-identical number set in step A as restraint conditions of the matching, processing character string matching operation based on the 3 kinds of characteristic, outputting the matching result, which is one of 8 kinds of retrieval manners, i.e. exact retrieval, discrete retrieval, cross retrieval, cross discrete retrieval, non-identical retrieval, discrete non-identical retrieval, cross non-identical retrieval, discrete cross non-identical retrieval. The method achieves a completely new information retrieval operating idea, and provides 8 kinds of retrieval manner. Furthermore the method may process qualitative retrieval, quantitative retrieval, faulttolerant retrieval or retrieval which has automatically set parameters. The operation is simply, flexible and convenient.
