Patent Searching and Data


Title:
PARTIAL COINCIDENCE RETRIEVING METHOD USING SIMILAR WORDS
Document Type and Number:
Japanese Patent JPS6299830
Kind Code:
A
Abstract:

PURPOSE: To prevent the increase of data on an index by providing a table which stores the data showing whether or not a pattern emerges in any area of the data on a character string to be retrieved.

CONSTITUTION: The similar word group identifiers S1 and S2 of the line containing a word ending in 'RICA' on a column 202 storing similar words are extracted with reference to a similar word table 106. Then the words 'AMERICA' and 'AFRICA' are extracted as the words having the identifier S1 or S2 on a column 201 storing the similar word identifiers and also having the existing flag set at '1' for a column 203 storing the existing flags with reference to the table 106. A single piece of the data 210 to be retrieved is extracted out of a storing area 107 fro data to be retrieved. Then a partial coincidence detecting mechanism 108 checks whether or not the data 210 contains 'AMERICA' or 'AFRICA'. If the partial coincidence is detected, the corresponding data 210 is displayed at a terminal 103 as one of retrieving data.
