A New Method of Chinese Address Extraction Based on Address Tree Model

Address is a spatial location encoding method of individual geographical area.In China,address planning is relatively backward due to the rapid development of the city,resulting in the presence of large number of non-standard address.The space constrain relationship of standard address model is analyzed in this paper and a new method of standard address extraction based on the tree model is proposed,which regards topological relationship as consistent criteria of space constraints.With this method,standard address can be extracted and errors can be excluded from non-standard address.Results indicate that higher math rate can be obtained with this method.
