| 摘 要： | 提出一种基于句子相似度的论文抄袭检测模型。利用局部词频指纹算法对大规模文档进行快速检测,找出疑似抄袭文档。根据最长有序公共子序列算法计算句子间的相似度,并标注抄袭细节,给出抄袭依据。在标准中文数据集SOGOU-T上进行的实验表明,该模型具有较强的局部信息挖掘能力,在一定程度上克服了现有的论文抄袭检测算法精度不高的缺点。

| Abstract: | A new model for plagiarism-identification of scientific papers based on sentence similarity is presented.Large-scale texts are quickly detected with Local Word-Frequency Fingerprin（tLWFF） to find suspected plagiarism ones.Sentence similari-ty is computed according to the Longest Sorted Common Subsequence（LSCS） between source texts and destination texts.The algorithm can mark plagiarism details,and show evidence.The identification experiments on the SOGOU-T database are done with this model.The results show it has higher information mining capacity,and partly overcomes the shortage of low-er precision on existing plagiarism-identification of scientific papers. |
