Abstract

The invention provides a thesis plagiarism detection method and system. The method comprises the following steps: recording materials by a comparison library; recording segmented words and corresponding word classes by a segmented word library; carrying out word segmentation by a word segmentation module; generating segmented word class characteristic values by a segmented word characteristic value generation module; determining segmented word free vector dimensions by a segmented word free vector dimension determination module; generating segmented word simplified vector dimensions by a segmented word simplified vector dimension generation module; generating segmented word characteristic vectors by a segmented word characteristic vector generation module; carrying out word segmentation on a to-be-authenticated document by a to-be-authenticated document word segmentation module so as to obtain a segmented word result; determining segmented word free vector dimensions by a to-be-authenticated document segmented word free vector dimension determination module; generating to-be-authenticated document segmented word simplified vector dimensions by a to-be-authenticated document segmented word simplified vector dimension generation module; generating to-be-authenticated document segmented word characteristic vectors by a to-be-authenticated document segmented word characteristic vector generation module; and carrying out similarity comparison.

Description

technical field [0001] The invention belongs to the field of text detection, in particular to a method and system for detecting plagiarism of papers. Background technique [0002] Paper plagiarism detection refers to judging whether a paper is suspected of plagiarizing the text content of one or more other documents. However, plagiarism is not exactly the same as copying, but it is possible to plagiarize the text content of other documents through various means such as semantic transformation, synonym replacement, or translation of foreign language documents. [0003] At present, there are two main methods of plagiarism detection technology in papers: one is through fingerprint recognition detection method, and the other is through the detection method based on the word frequency statistics of paragraphs in the text. The so-called fingerprint recognition refers to extracting some data characteristic strings called fingerprints from the submitted original text content, and j...
