Embodiment Construction

[0042] The present application will be described in detail below in conjunction with the accompanying drawings, and the specific operation methods in the method embodiments can also be applied to the device embodiments.

[0043] In the prior art, when determining whether two enterprise names match, in addition to manual comparison, a computer can also be used to perform full-character matching. However, this approach may be subject to misjudgment. For example, if the two company names to be matched are "Lenovo Company" and "Baidu Company", the existing full-character matching method is used, because the word "company" in the string "Lenovo Company" It is equal to the word "company" in the character string "Baidu Company", so the prior art may consider that "Lenovo Company" and "Baidu Company" match. Obviously, this perception is wrong.

[0044] Based on this, an embodiment of the present invention provides a string matching method, such as figure 1 As shown, it is a schemat...

Abstract

The invention discloses a string matching method and device. The method comprises: after obtaining the first string and the second string, word segmentation is performed on two strings, fields corresponding to the words included in the two strings are determined, the matching degree between the two strings can be determined according to the weight value of each field, if the matching degree is greater than the preset threshold value, the two strings can be considered to match. The matching degree of the two strings can be determined according to the weight value of each field. The weight valueof each field can be determined according to the sample string. Thus, by setting the weight values of different fields, the accuracy of matching between different strings can be improved. Further, compared with the manual comparison method in the prior art, the embodiment of the invention does not require manual comparison, effectively reduces the human cost, can simplify the operation of matching the enterprise name, and can also shorten the matching time.

Description

technical field [0001] The present invention relates to the field of data science, in particular to a character string matching method and device. Background technique [0002] Enterprise name matching is a very important technology in the field of risk control. For example, in the financial industry, especially in the credit industry, customers are often required to fill in the company name for risk management, and the company name filled in by the customer is matched. For example, you can use the company name filled in by the customer to match it with the company name in the credit report to see if the customer worked for the company before; Whether the customer has colleagues who are also customers of this institution. [0003] When matching enterprise names in the prior art, manual comparison is usually used for matching, that is, different enterprise names are considered to be matched. Obviously, this method has high labor costs, and the operation is complicated and ...
