However, in practical applications, there may be a certain difference in length between the address provided by the user to the merchant and the receiving address reserved by the user on the platform, but in fact it is still the same address
Therefore, in this case, when the platform determines whether the two addresses are the same, there may be misjudgment

Embodiment Construction

[0051] In related technologies, when determining whether two character strings (such as detailed addresses) are the same character string, it is usually by calculating the similarity between the two character strings, and then judging the two character strings by the similarity Is it the same.

[0052] Among them, when calculating the similarity between two strings, it can usually be achieved in the following ways:

[0053] In one embodiment shown, word segmentation can be performed on two character strings that need to be judged the same, the two character strings can be converted into structured data, and then the two characters can be calculated based on the structured data The similarity of strings; for example, you can set a word segmentation length, and perform text segmentation on the two strings according to the word segmentation length to obtain several text segmentation units with the same length, and then these text switching units obtained based on text segmentatio...

Abstract

The invention provides a same character string judgment method and apparatus. The method comprises the steps of calculating an editing distance between a first character string and a second character string; performing adaptation on the lengths of the first character string and the second character string based on the editing distance, and calculating the similarity based on the adapted lengths of the first character string and the second character string; and judging whether the first character string is the same as the second character string or not based on the similarity. According to the method and the apparatus, the accuracy of similarity calculation can be improved; and when whether the first character string is the same as the second character string or not is judged based on the similarity, the accuracy of a judgment result can be remarkably improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for judging identical character strings. Background technique [0002] On the e-commerce platform, in order to avoid fraud caused by users uploading false address information, the platform usually helps merchants verify the work address or home address uploaded by the user to determine whether the address uploaded by the user is the real and valid address of the user. For example, the platform can compare the address provided by the user to the merchant with the real receiving address reserved by the user on the platform to determine whether it is the same address. However, in practical applications, there may be a certain difference in length between the address provided by the user to the merchant and the receiving address reserved by the user on the platform, but in fact they are still the same address. Therefore, in this case, when the platform det...
