基于局部词频指纹的论文抄袭检测算法
Plagiarism-detection Algorithm for Scientific Papers Based on Local Word-frequency Fingerprint
摘要
Abstract
An algorithm for plagiarism-detection of scientific papers based on local word-frequency fingerprint is presented. Sentence is regarded as the basic component elements of a document, and extracting efficient keywords, sorting and reconstructing them. According to the code and word-frequency, the fingerprints are get to compute text similarity degree. The identification experiments on SOGOU-T database are done with the algorithm. Experimental results show that it partly overcomes the shortage of existing plagiarism-detection of scientific papers, and it has better performance on identification precision and identification speed.关键词
