Plagiarism detection is the process of locating text reuse within a suspicious document. The plagiarism detection corpora are used for evaluating plagiarism detection systems. In this paper, we present a bilingual PersianEnglish plagiarism detection corpus. We provide our corpus for the task of text alignment corpus construction in the PAN 2015 competition. Our approach is based on parallel cor...

We present our hybrid system for the PAN challenge at CLEF 2010. Our system performs plagiarism detection for translated and non-translated externally as well as intrinsically plagiarized document passages. Our external plagiarism detection approach is formulated as an information retrieval problem, using heuristic post processing to arrive at the final detection results. For the retrieval step...

The simple access to texts on digital libraries and the WWW has led to an increased number of plagiarism cases in recent years, which renders manual plagiarism detection infeasible at large. Various methods for automatic plagiarism detection have been developed whose objective is to assist human experts to analyze documents for plagiarism. Unlike other tasks in natural language processing and i...

Extrinsic plagiarism detection gathered the attention of many researchers lately. Plagiarism process began to be more and more difficult to be detected due to appearance of other sophisticated plagiarism approaches other than direct copy and paste such as (phrase rephrasing, word shuffling, semantic substitution, etc...). In this paper, we present RDI system for extrinsic plagiarism detection (...

Plagiarism; an un-attributed reuse of text, is very significant problem specifically for higher education institutions. Consequently, a number of automated plagiarism detection system have been developed to cater this problem. The comparison of these automated plagiarism detection systems is difficult sue to problem in collecting real cases of plagiarism by students / scholars. This paper descr...

In this paper we present an approach to detect external plagiarism based on textual similarity. This is an efficient and precise method that can be applied over large sets of documents. The system that we have developed contains a first phase of document selection that uses a variant of tf -idf applied over the terms that appear in the two documents of the pair being compared. After this is don...

Plagiarism detection systems comprise various approaches that aim to create a fair environment for academic publications and appropriately acknowledge the authors’ works. While the need for a reliable and performant plagiarism detection system increases with an increasing amount of publications, current systems still have shortcomings. Particularly intelligent research plagiarism detection stil...

The problem of academic plagiarism has been present for centuries. Yet, the widespread dissemination of information technology, including the internet, made plagiarising much easier. Consequently, methods and systems aiding in the detection of plagiarism have attracted much research within the last two decades. Researchers proposed a variety of solutions, which we will review comprehensively in...

The automated detection of plagiarism is an information retrieval task of increasing importance as the volume of readily accessible information on the web expands. A major shortcoming of current automated plagiarism detection approaches is their dependence on high character-based similarity. As a result, heavily disguised plagiarism forms, such as paraphrases, translated plagiarism, or structur...
