Research Of Paper Originality Detection Technology Based On The Citation

In recent years,academic misconduct controversy is often seen and widely criticized.Plagiarism is so widespread that it is poisoning our life silently like a cancer.At present existing plagiarism detection systems extract text features based on characters almost.They are capable of detecting verbatim and moderately disguised copies of text reliably.However,the cleverly veiled and re-structured real-world plagiarism more commonly found in research contains insufficient character based similarities,making it undetectable by current plagiarism detection system.On the basis of summarizing the domestic and foreign text plagiarism and citation analysis,this paper researches plagiarism from the perspective of citation,and designs the citation characteristics of the text to analyze the citation.Firstly,the experimental data are processed,then the text is separated from the references.Segment the reference string to create a bibliography list.According to the author and the publication year of the bibliography to locate citation,and use the parser to extract citation.Next analyze the list of bibliographies,and proceed to the next stage if the shared bibliography exceeds a certain threshold.Immediately analyze the longest public reference sequence.And it is eliminated from the experimental corpus if the score is less than the certain score.Finally conduct the citation analysis.Measure the degree of text plagiarism by comparing the maximum overlapping number of citation block.At last the proposed method is applied to the experimental data,and the good results verify the effectiveness of the proposed method.
