Problems solved by technology

At present, there are many address matching technologies in the existing technology. Some address matching technologies do not use word segmentation to process addresses, resulting in very limited types of addresses that can be processed, and high pre-processing requirements.
There are also some address matching technolog

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with specific embodiments.

[0026]An address matching method, which adopts a layered and progressive matching method, specifically includes four steps of fast matching, latitude and longitude matching, fuzzy matching and manual judgment:

[0027] a. Quick match:

[0028] Import the address information to be matched with the pre-test confidence index that meets the standard into the fast matching channel, perform precise matching on each address element, and use the chain supplementary mechanism to appropriately supplement the matching;

[0029] If the other elements are successfully matched except for the missing item, the entire address is judged as a successful match, and the posterior confidence index is recorded and calculated. If any item does not match, the match is judged as a failure;

[0030] The address information that fails to match and the address information that does not meet the pre...

Abstract

The invention discloses an address matching method. A step-by-step progressive matching method is adopted. The method concretely comprises four steps of fast matching, longitude and latitude matching, fuzzy matching and manual judgment, wherein in the fast matching step, high-quality target addresses are subjected to precise matching, and a chain type complementary mechanism is used for proper complementary matching; in the longitude and latitude matching step, the target addresses and adjacent cells are matched according to longitude and latitude information provided by a map service provider; in the fuzzy matching step, a fuzzy index is used for matching the target addresses and similar cells; and a manual judgment mechanism is used for checking and controlling the matching result. The address matching method also comprises an address word segmentation technology and an address matching accuracy confidence index mechanism. The address matching method has the advantages that the matching efficiency is improved under the condition of ensuring the high matching success rate; the problem of multiple-address matching technology composition application is solved; the success rate and the fault tolerance of the address matching are improved to a great degree; and meanwhile, a series of optimization mechanisms are used for ensuring the program running efficiency.

Description

technical field [0001] The invention belongs to the technical field of geographic information, and in particular relates to an address matching method. Background technique [0002] Address matching is the process of establishing a correspondence between a literal description address and its geographic location coordinates. The address matching service follows specific steps to find a match for an address. First, the address is standardized; then the server searches address matching reference data to find potential locations; assigns a score to each candidate location based on its proximity to the address, and finally The highest value matches this address. At present, there are many address matching technologies in the prior art, and some address matching technologies do not use word segmentation to process addresses, resulting in very limited types of addresses that can be processed and high requirements for pre-processing. There are also some address matching technologi...
