03/14/2017 - Focused on the country and post code information. Extracted country and post code information from addrline1 and addrline2 columns for patents from Japan and South Korea. The problem needed to be solved is that the post code from some countries follows the same pattern of the street code. For example, based on the pattern of [three digits-three digits], records from South Korea and German(some) are extracted.
