本文针对这类情况给出了一种基于监督学习方法的内部抄袭检测方法
并给出了平台在PAN'09语料上的内部抄袭检测的实验结果
主要研究方向：文本抄袭检测
抄袭检测任务旨在该参考资料集合中搜索与待检测文章的相似度大于一定阈值的文章
内部抄袭检测
） Abstract： Existing research on text plagiarism detection mainly focuses on external plagiarism detection which a reference collection is assumed to be given and the plagiarism detection task aims to compare suspicious documents against the collection to find the plagiarism articles with high similarity
The results of existing study have perfomed well in identifying external plagiarism sections
However, in the real world, the reference collection is impossible to get
This paper focuses on this case and proposes an intrinsic plagiarism detection framework with machine learning approaches
The instances creation and the features selection are presented in detail
The experiment studies are conducted on PAN'09 corpus
The experimental results demonstrate the effectiveness of our approach to intrinsic pagiarism
