METHOD AND DEVICE FOR SEARCH OF IMPORTANT PERSON, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To search for a person important for an arbitrary person in consideration of indirect human relationships and with a smaller calculation amount for the number of persons to be treated.

SOLUTION: An important person search device 100 searches a person important for the arbitrary person by human relationship information showing whether two arbitrary persons have human relationships and hobby information showing hobbies of respective persons with respect to a plurality of persons. A center ID human rank calculation unit 200 uses a prescribed recurrence formula (formula (1)) expressing a Markov process to calculate human ranks representing degree of importance for each of other persons for a central person based on the human relationship information. A center ID hobby vector storage unit 300 generates hobby vectors from the hobby information. A center ID human rank-hobby coupling score calculation unit 400 applies human ranks and hobby vectors to a prescribed human relationship score calculation formula (formula (2)) to calculate human relationship scores of the other persons for the central person.
