Text Plagiarism Checker Using Friendship Graphs

The paper proposes a method to check whether two documents are having textual plagiarism or not. This technique is based on Extrinsic Plagiarism Detection. The technique that is applied here is quite similar to the one that is used to grade the short answers. The triplets and associated information are extracted from both texts and are stored in friendship matrices. Then these two friendship matrices are compared and a similarity percentage is calculated. This similarity percentage is used to take decisions on the plagiarized paper. This technique can detect copy paste plagiarism and disguised plagiarism.
