MATCHING METHOD FOR BUILDING AND MAP, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To highly accurately relate a specified building to a building in map information by calculating an index value for indicating the probability of the pair relation of the specified building and a building name in the map infor mation based on the values of both character string matching rate and address matching degree and relating them. SOLUTION: A link reliability calculation program 12 calculates link reliability between a record read from a database 7 and the building read from a map database 9 and a map matching processing program 5 relates the building judged as corresponding in the map database 9 based on the value calculated by the link reliability calculation program 12. A link reliability calculation method setting program 13 specifies a calculation method when the link reliability calculation program 12 calculates the link reliability. Normally, it is not required to change the setting of the calculation method of the link reliability, however, the calculation method of the link reliability is adjusted matched with the characteristics of the database 7.
