TRACEABILITY MANAGEMENT APPARATUS, TRACEABILITY MANAGEMENT METHOD, AND TRACEABILITY MANAGEMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To make it easier to ensure traceability between documents.SOLUTION: An exclusion character string data creation unit 105 of a traceability management apparatus 200 acquires a character string indicated by data stored in a traceability information database 106 as a first character string. The exclusion character string data creation unit 105 searches for the first character string in a document 301, and excludes some character strings from the first character string to create a second character string if the number of occurrences of the first character string is lower than a threshold value. Then, the exclusion character string data creation unit 105 searches for the second character string in the document 301, and updates the data stored in the traceability information database 106 to data indicating the second character string instead of the first character string if the number of occurrences of the second character string exceeds the threshold value.SELECTED DRAWING: Figure 1
