17. A processing system comprising: a processor; a memory coupled to the processor and containing a program that, when executed by the processor, performs an operation for parsing an address, comprising: separating an address into a plurality of tokens; performing an initial pass on the plurality of tokens based on geographic region-specific configuration information for the address to determine at least one candidate classification for each of the tokens in the plurality of tokens, wherein the initial token meaning discovery pass is performed without context-specific information for the address; and performing one or more additional passes on the plurality of tokens based on the geographic region-specific configuration information for the address to determine a final classification of each token in the address, wherein the final classification is selected from the determined candidate classifications for the token, and wherein the one or more additional passes are performed with context-specific information relating the token to one or more other tokens in the plurality of tokens.
