In this paper, we describe an approach to create monolingual English plagiarism detection corpus for the task of text alignment corpus construction in PAN 2015 competition. We propose two different obfuscation methods to fragment obfuscation for creating the cases of plagiarism. The first method is an artificial obfuscation which consists of variety of obfuscation strategies such as synonym substitution, random change of order, POS preserving change of order and addition/deletion. The second obfuscation method is a simulated obfusca- tion, in which the SemEval dataset is used for creating the cases of plagiarism by using pairs of sentences with their similarity scores.
