gbdt_divider = GBDTNameDivider() # GBDTNameDivider is slow but accuracy is 99.9%
divided_name = gbdt_divider.divide_name("菅義偉")

NameDivider API

NameDivider API is a Docker container that provides a RESTful API for dividing the Japanese full name into a family name and a given name.

        [
            {"family":"竈門","given":"炭治郎","separator":" ","score":0.3004587452426102,"algorithm":"kanji_feature"},
            {"family":"竈門","given":"禰豆子","separator":" ","score":0.30480429696983175,"algorithm":"kanji_feature"}
