Title:
LACKING DATA COMPLEMENTING METHOD AND LACKING DATA COMPLEMENTING SYSTEM
Document Type and Number:
Japanese Patent JP3654193
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lacking data complementing method and a lacking data complementing system capable of automatically computing the complementary data of a lacking part of sample data to minimize an operator's labor.
SOLUTION: This lacking data complementing method and system comprise a lack detecting and dividing processing step (part) for detecting lacking data with the lack of partial feature out of a sample data group stored in a database, and dividing the sample data in the lacking data and normal data without a lack, and a complementary processing step (part) for obtaining the normal data similar to the lacking data using a prescribed similarity scale, using the data of a feature corresponding to the lacking feature of the lacking data, in the obtained normal data, as complementary data, and substituting the complementary data for the lacking feature of the lacking data to complement the lacking data.
