Method for converting non-standard address into standard address and encoding standard address

The invention relates to a method for converting a non-standard address into a standard address and encoding the standard address. The conversion method comprises the following steps: extracting the non-standard address; carrying out Chinese word segmentation; carrying out two-segment division on the Chinese word segmentation result, and dividing the non-standard address into a first front segmentdescription and a rear segment description, wherein the first front section description is non-standard description; converting the first front description into GPS coordinates; inversely convertingthe GPS coordinates into a second front description, wherein the second front section description is standard description, the second data file stores a corresponding relation between the GPS coordinates and the specification description; for the second front section description, extracting a standard front section description; and obtaining a standard address through a rear section description which is superposed after th
