Abstract

The present invention is applicable to the technical field of data processing, and provides a method for acquiring text similarity, a terminal device, and a medium. The method comprises: after acquiring a plurality of word segments corresponding to each to-be-analyzed text, storing the word segments in a word bag; acquiring TF-IDF information of each word segment in a word bag model; based on theTF-IDF information associated with each to-be-analyzed text, generating text set feature matrices corresponding to the plurality of comparison texts and text vectors corresponding to the reference texts respectively; performing singular value decomposition on the text set feature matrices, and according to the obtained word feature matrices and the feature vector weight matrices, performing inverse mapping processing on the text vectors to obtain second feature vectors; and respectively calculating the similarity between each second feature vector and the first feature vector, and outputting acalculation result as the similarity between the preset text and the comparison text matched by the second feature vector. According to the technical scheme of the present invention, the calculationaccuracy of the text similarity is improved, and the comparison efficiency of the text is improved.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method for acquiring text similarity, a terminal device and a computer-readable storage medium. Background technique [0002] Text similarity is used to measure the degree of similarity between texts. In the traditional way, the text similarity can be determined by human judgment. However, manually judging a large number of similar texts is often a time-consuming and cumbersome task. Therefore, in order to solve this problem, with the continuous development of scientific research, word frequency statistics and vector space models such as simhash have been derived. These vector space models calculate text similarity by identifying words that are common in two articles, and based on information such as the presence or absence of words and the word frequency of each word. Therefore, only when there are a large number of identical words in two articles, the ca...
