Our company's chain POI database (Location Technology) has standardized its address data.
The address was obtained from the company's homepage and, in some cases, it is not complete. Specifically, the postcode and prefecture data are not present in the following case.
E.g. 函館市湯川町3丁目14-5 イオン湯川店 1F
We developed a program to substitute the missing components and complete the address.
E.g. 〒042-0932 北海道函館市湯川町三丁目 14-5 イオン湯川店 1F
