The design and implementation of address matching engine

摘要

In real life there are various types of information, not all information contains a clear geographical coordinates of the spatial information, a large portion of non-spatial information is relevant to space location, such as address, ID card number, telephone number, postcode, and so on, such information does not directly contain spatial coordinates, but implicit location information. In this paper, a engine, which natural language matches address, based on the word segmentation technology has been put forward. The engine can extract address name, ID card number, telephone number information from natural language and convert them to a clear geographical coordinates or the bounds of geographical coordinates. It will be the vital link between non-spatial information and spatial information.
