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
The invention belongs to technical field of geographic information, relate to a kind of confidence index mechanism of matching addresses accuracy specifically.
Background technology
Matching addresses the description address of character property and the geographical position coordinates in its space is set up the process of corresponding relation.Matching addresses service is address search match objects according to specific step, first will by Address Standardization; Then server search matching addresses reference data, searches potential position; Be that each position candidate specifies score value according to the degree of closeness with address, finally with score value the highest mate this address.The information that matching addresses technology of the prior art provides usually is comparatively hard to understand, and not intuitively, index weight arranges not closing to reality situation, and reflection address quality is not accurate enough.In prior art, a kind of confidence index of very perfect matching addresses accuracy is not machine-processed, even if having approximation technique similar with it also to there is index weight arrange inadequate closing to reality situation, the situations such as reflection address quality is not accurate enough, thus cause the working strength adding address auditor, reduce work efficiency.
Summary of the invention
The present invention in order to overcome prior art exist deficiency, provide a kind of can reduce working strength, increase work efficiency matching addresses accuracy confidence index mechanism.
The present invention is achieved by the following technical solutions: a kind of confidence index mechanism of matching addresses accuracy, it is a kind of address quality indication mechanism of integrating system, every Address factor can the contribution degree of successful match distribute fixing initial score value or setting fixing weight to address according to it in whole piece address information, then carries out suitable weighting according to the information integrity of every Address factor and the initial score value of accuracy to this key element and draws score value after weighting; If the successful match of a certain key element just must be achieved by fuzzy matching, then the integration of this key element will be multiplied by a confidence coefficient, described confidence coefficient value between 0 and 1, the concrete of confidence coefficient value is neglected greatly fuzzy degree and determines, and after every Address factor weighting of an address information, the summation of score value is the confidence index of this address information.
Comprise in the confidence index mechanism of described matching addresses accuracy and test confidence index and posteriority confidence index two kinds of confidence indexs in advance, described two kinds of confidence indexs use common integration system, but described two kinds of confidence indexs are used in the different phase of whole matching addresses flow process.
Described test in advance confidence index be used in the address participle stage after, before the Rapid matching stage, whether described confidence index of testing in advance reaches Rapid matching standard for estimating address quality, improve matching efficiency.
After described posteriority confidence index is used in the fuzzy matching stage, before artificial decision stage, described posteriority confidence index is that the artificial selection that judges and decision-making provide support.
The invention has the beneficial effects as follows: the confidence index mechanism of matching addresses accuracy of the present invention comprises two kinds of confidence indexs, both confidence index and posteriority confidence index had been tested in advance, test confidence index in advance and whether reach Rapid matching standard for estimating address quality, improve matching efficiency; Posteriority confidence index is that the artificial selection that judges and decision-making provide support.The machine-processed accuracy for every bar address date of confidence index of matching addresses accuracy of the present invention provides directly perceived, understandable instruction, and creates good condition for matching result is visual.The confidence index mechanism of matching addresses accuracy of the present invention can overcome the defects such as matching addresses information in prior art is hard to understand, directly perceived not, reflection address quality is not accurate enough, solve the technical matters of display address directly perceived quality, auditor is helped to make a decision, decrease working strength, improve work efficiency.
Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
A kind of confidence index mechanism of matching addresses accuracy, it is a kind of address quality indication mechanism of integrating system, every Address factor can the contribution degree of successful match distribute fixing initial score value or setting fixing weight to address according to it in whole piece address information, then carries out suitable weighting according to the information integrity of every Address factor and the initial score value of accuracy to this key element and draws score value after weighting.Such as: if the successful match of a certain key element just must be achieved by fuzzy matching, then the integration of this key element will be multiplied by a confidence coefficient, confidence coefficient value between 0 and 1, the concrete of confidence coefficient value is neglected greatly fuzzy degree and determines, and after every Address factor weighting of an address information, the summation of score value is the confidence index of this address information.
Comprise two kinds of confidence indexs in confidence index mechanism of the present invention: test confidence index and posteriority confidence index in advance, two kinds of confidence indexs use common integration system, but two kinds of confidence indexs are used in the different phase of whole matching addresses flow process.Test in advance confidence index be used in the address participle stage after, before the Rapid matching stage, test confidence index in advance and whether reach Rapid matching standard for estimating address quality, improve matching efficiency.After posteriority confidence index is used in the fuzzy matching stage, before artificial decision stage, posteriority confidence index is that the artificial selection that judges and decision-making provide support.
Finally should be noted that; above content is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; the simple modification that those of ordinary skill in the art carries out technical scheme of the present invention or equivalently to replace, does not all depart from essence and the scope of technical solution of the present invention.
