Abstract: As points of interest (POI)on the internet, exists widely incomplete addresses and inconsistent literal expressions, a fast standardization processing method of network POIs address information based on spatial constraints was proposed. Based on the model of the extensible address expression, first of all, address information of POI was segmented and extracted. Address elements are updated by means of matching with the address tree layer by layer. Then, by defining four types of positional relations, corresponding set are selected from standard POI library as candidate for enrichment and amendment of non-standard address. At last, the fast standardized processing of POI address information was achieved with the help of backtracking address elements with minimum granularity. Experiments in this paper proved that the standardization processing of an address can be realized by means of this method with higher accuracy in order to build the address database.
