Problems solved by technology

[0004] The technical problem to be solved in the present invention is to provide an address matching method for the limitations and deficiencies of the prior art, which combines the dictionary-based address matching method with the rule-based address matching method, and then combines natural language processing technology. The address matching method is improved, which solves the problem of ambiguity segmentation in the single address matching method and the low recognition rate of new words, which makes the accuracy of the address matching result low, so as to improve the accuracy of address matching

Embodiment 1

[0033] Embodiment 1: as Figure 1-4 As shown, an address matching method, first establishes word segmentation dictionary, address classification dictionary and common address acronym replacement dictionary; then preprocesses the input address string to be matched; The different word segmentation results based on reverse maximum matching are processed twice with the rule-based address matching method and natural language processing technology; finally, all the word segmentation results are matched to the database and then reweighted to obtain several matching results, and finally through similarity Calculate to obtain the address string with the highest similarity.

[0034] The specific steps are:

[0035] ① Establish word segmentation dictionaries, address classification dictionaries and common address acronyms replacement dictionaries.

[0036] ②Enter the address string to be matched.

[0037] ③Preprocess the input address string to be matched.

[0038] ④Using the rule-ba...

Abstract

The invention relates to an address matching method, belonging to the technical field of geographic information data processing. The method comprises the steps of firstly establishing a dictionary ofword segmentation, a hierarchical dictionary of address and an alternative dictionary of common address abbreviations; and then preprocessing the input address string to be matched; carrying out the secondary processing on the different segmentation results based on forward maximum matching and reverse maximum matching in the pre-procesing by a rule-based address matching method and a natural language processing technology; finally matching all the segmentation results with the database and weighting again to obtain several matching results, finally obtaining the address string with the highest similarity through similarity calculation. The invention mainly solves the ambiguity segmentation of a single address matching method and the low recognition rate of the new words by fusing the address matching method based on dictionary and the address matching method based on rule and combining the natural language processing technology, so that the low accuracy phenomenon of the address matching results is avoided, and the accuracy of address matching is improved.

Description

technical field [0001] The invention relates to an address matching method and belongs to the technical field of geographic information data processing. Background technique [0002] With the rapid development and wide application of geographic information technology, address matching technology can associate text information containing locations with spatial information, thereby providing services such as data analysis, positioning, mapping, and visualization. High-accuracy matching plays an indispensable role in the construction of digital cities and people's lives, and the social and economic benefits are extremely significant. [0003] Generally, although the dictionary-based address matching method can improve efficiency and accuracy to a certain extent, the matching process relies too much on the dictionary, and the accuracy of address matching is low in the case of unregistered words and noise words; , although the rule-based address matching method solves the proble...
