Abstract: A method for obtaining trademark similarity is disclosed, and includes: obtaining character information of a first trademark and character information of a second trademark; constructing a feature information set according to the character information of the first trademark and the character information of the second trademark; and obtaining a degree of similarity between the first trademark and the second trademark based on the feature information set. By automatically constructing multiple pieces of feature information for evaluating trademark similarity, the method can quickly and accurately obtain a degree of similarity between trademarks, and at the same time, can also avoid the problems of manual design rules or inaccurate calculation of manual design rules.
