Problems solved by technology

The information given by the address matching technology in the existing technology is usually relatively obscure, not intuitive enough, and the index weight setting is not close to the actual situation, reflecting that the quality of the address is not accurate enough
In the prior art, there is no perfect confidence index mechanism for address matching accuracy. Even if there is a similar approximation technology, the index weight setting is not close to the actual situation, and the address quality is not accurate enough, which leads to an increase in The work intensity of address auditors reduces work efficiency

Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with specific embodiments.

[0010] A confidence index mechanism for address matching accuracy, which is a point-based address quality marking mechanism. Each address element is assigned a fixed initial score based on its contribution to the successful address matching in the entire address information Or set a fixed weight, and then properly weight the initial score of each address element according to the information completeness and accuracy of the element to obtain the weighted score. For example: if the successful matching of an element must be achieved through fuzzy matching, then the integral of this element should be multiplied by a confidence coefficient, the confidence coefficient takes a value between 0 and 1, and the specific value of the confidence coefficient depends on Depending on the degree of fuzziness, the sum of the weighted scores of each address element of an address information...

Abstract

The invention discloses a confidence index mechanism of address matching accuracy. According to the confidence index mechanism, a fixed initial score is distributed, or fixed weight is set for each address element according to the contribution degree of the address element to successful address matching in a whole piece of address information; appropriate weighting is performed on the initial score of the address element according to the integrity and accuracy of the information of the address elements, so that a weighted score can be obtained; if the successful matching of a certain element is realized only through fuzzy matching, and the integral of the element should be multiplied by a confidence factor; and the sum of the weighted scores of the address elements in one piece of address information is the confidence index of the address information. With the confidence index mechanism of the invention adopted, intuitive and understandable indication can be provided for the accuracy of each piece of address information; a good condition can be created for the visualization of matching results; technical problems in intuitive display of address quality can be solved; and audit personnel can be assisted to make decisions, and work intensity can be reduced, and work efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of geographic information, and in particular relates to a confidence index mechanism for address matching accuracy. 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. The information given by the address matching technology in the prior art is usually relatively obscure and not intuitive enough, and the setting of the index weight is not close to the actual situation, which reflects the quality of the address is not accurate enough. In the prior art, ...
