摘要

PROBLEM TO BE SOLVED: To provide a questionnaire method and system, allowing verification of whether or not a sample group of a questionnaire target represents a population, and allowing extraction of the sample group from the population without deviation.

SOLUTION: A sample database 1 stores a large number of users Ui and the number ki of kith thereof. A target storage part 2 stores a target degree property. A sample group selection part 3 selects the sample group Uj of the questionnaire target from the sample database 1. A kith number acquisition part 4 obtains the number kj of kith of the selected sample group Uj from the sample database 1. A degree property calculation part 5 calculates a degree property related to the number kj of the kith of the sample group Uj based on the obtained number kj of the kith. A verification part 6 compares the degree property of the sample group Uj and the target degree property to verify adaptability between this sample group Uj and a social network structure, and outputs a verification result thereof.
