Chinese address processing method and system

Abstract

The invention is applicable to the field of data processing and provides a Chinese address processing method and system. The method includes the steps that N first word segment sets of a to-be-segmented address are obtained through N preset algorithms, and each preset algorithm is used for segmenting the to-be-segmented address on the basis of a kind of character statistical characteristics; the N first word segment sets are gathered through a word segment combination algorithm to obtain a second word segment set; the second word segment set with abnormal segmentation conditions is processed through the segmentation correction algorithm to obtain a third word segment set; the word segment, ended with an address factor, in the third word segment set serves as a first segmentation result, and word segments ended without address factors are corrected and combined to obtain a second segmentation result; aggregate output of the first segmentation result and the second segmentation result is a final segmentation result of the to-be-segmented address. Word segments not conforming to actual semanteme can be adjusted stage by stage, address word recognition precision is improved, and the problem that an existing segmentation method is low in segmentation accuracy is solved.

Description

technical field [0001] The invention belongs to the field of data processing, in particular to a Chinese address processing method and system. Background technique [0002] In daily production and life, addresses are one of the most common reference systems that use natural language to describe geographic locations. In GIS (Geographic Information System, Geographic Information System), address coding (Geocoding) is the process of spatially locating the information described by the address and establishing the connection between spatial information and non-spatial information. [0003] The core technology of urban geocoding includes address element analysis. It is the process of splitting a complete address described in natural language into a set of address elements with a clear spatial range. This process can be regarded as a specific Chinese address word segmentation task. In terms of automatic address parsing, Chinese addresses are usually described using natural langua...
