Embodiment Construction

[0030] As described in the background art, there is an urgent need for a text matching method that can improve the matching accuracy.

[0031] In the prior art, an unsupervised algorithm is usually used to extract the keywords contained in the text, and then directly based on the word vector of the keywords in the text, the similarity between the texts is calculated, and finally the matching result of the text is determined by the similarity. After research, it is found that using such a scheme, when the length of the text is long, there may be a lot of redundancy in the content of the text, which will cause the characteristics of the text to not be prominent. At this time, the similarity between the texts is obtained according to the word vector. The actual degree of similarity between texts cannot be accurately characterized.

[0032] In addition, in the prior art, a method based on deep learning is usually used for text matching. Specifically, training samples are used to ...

Abstract

The invention discloses a text matching method and device, a storage medium and a terminal. The method comprises the steps of obtaining a first text; constructing an element graph of the first text; semantic information of the first text is extracted; semantic information and structural information of a second text are obtained, the structural information of the second text comprises an element graph and / or graph embedding feature information of the second text, and the graph embedding feature information is obtained through calculation according to the element graph; and determining a matching result of the first text and the second text according to the semantic information and the element graph of the first text and the semantic information and the structure information of the second text. Through the scheme provided by the invention, the text matching accuracy can be improved.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, and in particular, to a text matching method and device, a storage medium and a terminal. Background technique [0002] With the development of artificial intelligence technology, the application of natural language processing (NLP) technology in various fields has become more and more extensive, and text matching technology has emerged as the times require. Among them, text matching is a technique used to measure the similarity or relatedness between texts. In the prior art, the accuracy of text matching still needs to be improved, especially when the length of the text is long, the matching accuracy is obviously reduced. [0003] Therefore, there is an urgent need for a text matching method that can improve the matching accuracy. SUMMARY OF THE INVENTION [0004] The technical problem solved by the present invention is how to improve the accuracy of text matching...
