Abstract

The present application relates to a method and apparatus for obtaining similar trademarks, a computer device and a storage medium. The method is based on the longest common subsequence, the longest common string, and the edit distance to determine the similarity of the character string integrity of the word mark and the prior trademark, thereby screening out similar trademarks with higher similarity and treating them again. The similarity between the word and the glyph is determined by the difference characters between the character trademark to be detected and the similarly preceding trademark. the comprehensive similarity is calculated by the overall character string judgment result and the character independent judgment result, and the prior trademark having high similarity degree is fed back to the user, the quick acquisition of the approximate trademark of the trademark to be detected is realized, and the efficiency of the approximate trademark search is improved. At the same time, the approximation judgment between the detected word mark and the prior trademark is synthesized by the overall judgment result of the string and the independent judgment result of the character. The results are determined to effectively improve the accuracy of the approximate trademark search.

Description

technical field

[0001] The present application relates to the technical field of information data processing, and in particular to a method, device, computer equipment and storage medium for acquiring similar trademarks. Background technique

[0002] At present, the similarity determination of word trademarks in the industry mainly relies on manual search of similar trademarks in the trademark database and judgment on the similarity between trademarks. The trademarks in the results are judged by similarity, and the processing speed of manual retrieval and judgment of similar trademarks is limited, resulting in low efficiency of trademark retrieval and examination. Contents of the invention

[0003] Based on this, it is necessary to provide a similar trademark acquisition method, device, computer equipment and storage medium for the technical problem that the processing speed of manual retrieval and determination of similar trademarks is limited, resulting in low efficiency...

Embodiment Construction

[0062] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0063] The method for obtaining similar trademarks provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The user sends the word mark to be detected to the server 104 through the terminal 102. After receiving the word mark to be detected, the server 104 screens out similar prior marks with higher character string similarity from the previous marks in the trademark database according to the word mark to be detected. trademark, and calculate the s...
