A text similarity analysis method and system for copyright authentication

Abstract

The invention provides a text similarity analysis method for copyright authentication, including: obtaining an original first text content and a second text content of an alleged infringement; performing feature extraction on the first text content to generate a text feature vector; using a pre-trained vector matching model to match the first text content with a sample in a sample library according to the text feature vector to obtain a target sample, wherein the sample comprises a sample editing text and a sample original text corresponding to the sample editing text; determining a model by using a pre-trained editing rule mode according to the consistency of the text features between the sample original text of the target sample and the corresponding sample editing text, and determiningan editing rule mode; judging whether the second text content conforms to the editing rule mode according to the editing rule mode, and judging that the text is similar if the second text content conforms to the editing rule mode. The invention judges whether the litigated infringement text content belongs to the original text content obtained by certain editing process, so as to solve the technical problems of low efficiency, poor accuracy and large subjective arbitrariness existing in the prior art through manual comparison.

Description

Technical field [0001] This application relates to the field of Internet application technology, and in particular to a text similarity analysis method and system for copyright authentication. Background technique [0002] With the rapid development of online media such as blogs and official accounts, more and more attention is paid to the copyright protection of online original text content. At present, online media often reproduce, excerpt, and even plagiarize text content without the permission of the original author, which seriously infringes the legal rights of copyright owners and is very detrimental to the healthy growth of online media platforms. [0003] At present, the copyright protection provided by online media for original authors mainly relies on the complaint mechanism. The original author is required to provide the infringer’s network address or registered official account, infringing text content, and original text content originally published by the author, which...
