DATA RELIABILITY CALCULATING DEVICE, DATA RELIABILITY CALCULATING METHOD, AND DATA RELIABILITY CALCULATING PROGRAM

摘要

This data reliability calculating device keeps a data user score for each data user of data, a data provider score for each data provider of data, and data reliability of each data item, and, when calculating the data reliability of a certain data item, calculates the data reliability of the data item on the basis of the data user score of the data user who has used the data item, the data provider score that has used the data item, and the data reliability of the source data of the data item. Specifically, when calculating the data reliability of a certain data item, a value obtained by adding up the sum of the data user scores of data users who are using the data item, the data provider score of the data provider of the data item, and the arithmetic average of the reliability of the source data is calculated as the data reliability of the data item. Thus, it is possible to present, when using a data item, a quantitative indicator of how reliable the data item being considered for use is.
