Abstract

The invention provides a text comparison method and a text comparison device, which help to solve the technical problems of low efficiency and low accuracy of text comparison in the prior art. The text comparison method of the present invention includes: calculating the Hamming distance between the first text and the second text; if the Hamming distance is less than the preset Hamming distance threshold, using the cosine algorithm to calculate the distance between the first text and the second text The cosine value of the first text and the second text are judged according to the cosine value and the Hamming distance according to preset rules, and then a corresponding prompt message is issued according to the similarity level.

Description

technical field [0001] The invention relates to the technical field of a computer and its software, in particular to a text comparison method and a text comparison device. Background technique [0002] In Internet technology and big data technology, text similarity comparison is often used. For example, in the search results page of a search engine, in order to remove duplicates, the same and similar text comparison will be used; in the product display page of an online shopping mall, in order to judge whether the products are the same or similar products, you can use the same and similar product description text In data mining and data analysis, it is often necessary to use text similarity comparison to judge the similarity between two or more different texts to achieve the corresponding application purpose. Among the existing text similarity query algorithms, the more famous ones are the cosine calculation method and the simhash algorithm proposed by Google. [0003] In ...
