Fuzzy Chinese address geographic evaluation method based on matching rule

Abstract

The invention relates to a fuzzy Chinese address geographic evaluation method based on a matching rule, which belongs to the field of the address evaluation of a geographic information system. The method comprises the following steps: firstly, reading in an address character string and a standard address base; inquiring and dividing administrative division parts in the address character string and filtering reduced target data sets; then realizing the segmentation and the matching of an address by means of a matching rule tree and a rule base in allusion to the fuzzy problems of address element incompletion, address ambiguity and the like frequently appearing in the address character string, and returning a matching record meeting requirements. The invention integrates two important links of address segmentation and database matching in geographic evaluation, realizes that the database matching of the address is completed while in segmentation, effectively solves the address matching problem of the fuzzy Chinese address and improves the accuracy and correctness of address matching.

Description

A Geographic Assignment Method of Fuzzy Chinese Addresses Based on Matching Rules technical field The invention belongs to the field of geographic information systems and relates to an address assignment method for fuzzy Chinese addresses. Background technique With the application and popularization of electronic maps, there are a large number of Chinese address data described by natural language in all walks of life, which need to be mapped to geographic coordinates and positioned on the electronic map, so that the original non-spatial data can obtain spatial coordinate information , Realize the integration and sharing of data from various departments and geographical areas. This requires the use of geographic (address) assignment technology, that is, the technology of converting text addresses into geographic coordinates. The geographic assignment method is generally divided into several steps such as address standardization, address word segmentation, database matching...

Problems solved by technology

The second reason is that our country's existing place names and address system are extremely complicated, and the address system is chaotic, disorderly, lacking regularity and unified standards.

Therefore, the existing foreign geographical assignment technology is not suitable for China's national conditions, and it is not feasible to directly apply foreign geographical assignment technology
