Abstract

For the issues of the similarity calculation and plagiarism detection from documents written in Uyghur, this paper proposed a content-based Uyghur plagiarism detection(U-PD) method. Firstly, it segmented the Uyghur texts, deleted the stop words, extracted the stems and replaced synonyms through the preprocessing stage, of which extraction stems were based on n-gram statistical models. Then, it calculated the hash value of each text block through the BKDRhash algorithm and constructed the hash fingerprint information of the entire document. Finally, according to the hash fingerprint information, it matched the document and document library at the document level, the paragraph level and the sentence level based on the RKR-GST matching algorithm, and obtained the similarity of the document, so as to realize plagiarism detection. The experimental evaluation in Uyghur documents shows that the proposed method can detect plagiarism documents accurately and is feasible and effective.
