Problems solved by technology

[0004] The existing method of expressing text similarity by calculating the distance between word vectors is the similarity of text from the perspective of semantics. Generally, the similarity of words used in the text is not considered, so the effect of evaluating text similarity is not very good

Abstract

A text similarity calculation method is applied to the technical field of computer application and comprises the following steps of respectively performing word segmentation processing on two to-be-processed texts to obtain two first vocabulary sets, and calculating first similarity of the two to-be-processed texts based on the two first vocabulary sets; inputting the two texts into a preset N-gram language model to obtain two second vocabulary sets, and calculating second similarity of the two texts based on the two second vocabulary sets; and calculating the similarity of the two texts basedon the first similarity and the second similarity according to a preset adjustment parameter of the first similarity and a preset adjustment parameter of the second similarity. The invention furtherprovides a text similarity calculation device and a storage medium. In the process, when the text similarity is calculated, the similarity between text semantics is considered, and the similarity of text words is also considered, so that the calculation of the text similarity is more accurate.

Description

technical field [0001] The present disclosure relates to the technical field of computer applications, in particular to a method, device and storage medium for calculating text similarity. Background technique [0002] Text similarity is a way to quantify the similarity between texts. In recent years, it has been widely used in information retrieval, document duplication detection, machine translation, public opinion monitoring and other fields. [0003] In the existing technology for calculating text similarity, the space vector model method is used to map the text into word vectors in the semantic space, and calculating the spatial distance between word vectors is a common practice for calculating text similarity. [0004] The existing method of expressing text similarity by calculating the distance between word vectors is the similarity of text from the perspective of semantics. Generally, the similarity of words used in the text is not considered, so the effect of evalua...
