Embodiment Construction
[0029] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.
[0030] figure 1 It is a schematic flowchart of the method for determining the similarity of documents based on semantic analysis in the embodiment of the present invention, as figure 1 As shown, the method includes the following steps:
[0031] Step 101: Divide each document to be compared into multiple parts;
[0032] Step 102: perform semantic analysis on each part to obtain a semantic analysis result of each part;
[0033] Step 103: Determine the weight value of each part of each document to be compared according to the semantic analysis result of each part; ...

The invention discloses a literature similarity determination method and device based on semantic analysis. The method comprises the following steps: dividing each literature to be compared into a plurality of parts; performing semantic analysis on each part to obtain a semantic analysis result of each part; according to the semantic analysis result of each part, determining a weight value of each part of each to-be-compared literature; according to the weight value of each part of each to-be-compared literature, obtaining a weighted average result of each to-be-compared literature; and determining the similarity between the to-be-compared literatures according to the weighted average result of each to-be-compared literature. According to the method, the weights of different parts of the literature can be accurately determined on the basis of semantic analysis, and then the literature similarity is accurately determined.
Description
technical field [0001] The invention relates to the technical field of artificial intelligence, and in particular, to a method and device for determining the similarity of documents based on semantic analysis. Background technique [0002] This section is intended to provide a background or context to the embodiments of the invention recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, when determining the similarity of documents in the prior art, according to manual experience, different weights are preset for different parts of the documents, and finally, according to the fixed weights set artificially, the result obtained by the weighted summation of the similarity of each part of the content is determined as the document. similarity. The existing methods for determining the similarity of documents set the weights based on experience, and the weight setting is inaccurate, which leads to the pr...
