Abstract: In a database system for map information, matching and retrieving operations are carried out between an attribute database associated with a business and a map database. A matching key word is separated into a common noun part and a proper noun part, a synonym and an abbreviated word are inferred by employing rules respectively. Furthermore, a candidate key word is inferred by employment of a rule for combining these results at an optimum state, whereby a matching process is performed. Another address database is employed so as to realize a mutual retrieving operation even when the attribute database is not matched with the map database.
