Plagiarism is considered as a major problem these days especially in case of academic institutions. Very often students present someone else’s work as their own and they are given credit for it. Therefore, we have to integrate plagiarism checking into the submission process which includes usage of plagiarism detection software. In this paper we focus on vulnerabilities of this software from the...

Academically dishonest behavior, such as cheating and plagiarism, presents a challenge on college campuses, exacerbated by new technologies which have increased the ease of academic dishonesty. The first section below provides material for promoting academic integrity in higher education. The second section focuses on resources for preventing and dealing with plagiarism in on-campus and online ...

In this paper we describe our approach at the PAN 2010 plagiarism detection competition. We refer to the system we have used in PAN’09. We then present the improvements we have tried since the PAN’09 competition, and their impact on the results on the development corpus. We describe our experiments with intrinsic plagiarism detection and evaluate them. We then discuss the computational cost of ...

Research in external plagiarism detection is mainly concerned with the comparison of the textual contents of a suspicious document against the contents of a collection of original documents. More recently, methods that try to detect plagiarism based on citation patterns have been proposed. These methods are particularly useful for detecting plagiarism in scientific publications. In this work, w...

In this paper, we describe our approach at the PAN 2012 plagiarism detection competition. Our candidate retrieval system is based on extraction of three different types of web queries with narrowing their execution by skipping certain passages of an input document. Our detailed comparison system detects common features of input document pair, computing valid intervals from them, and then mergin...

This paper is a deep investigation of cross-language plagiarism detection methods on a new recently introduced open dataset, which contains parallel and comparable collections of documents with multiple characteristics (different genres, languages and sizes of texts). We investigate cross-language plagiarism detection methods for 6 language pairs on 2 granularities of text units in order to dra...

This study uses purpose-built test data and empirical experiments to report on the performance of four web plagiarism detection systems: TurnitIn, SafeAssignment, Plagiarism-Finder and EVE. In addition to measuring accuracy of detection, we evaluated the extent to which these systems produce false detections. We obtained the test data from multiple sources and edited it in several ways to conce...

Plagiarism is a problem in many education institutions around the world. Preventing digital plagiarism requires enormous amount of work from educator. In this paper we concentrate on implementation of well known anti-plagiarism algorithm for local and global search for the original source of plagiarized assignment. We first discuss problems in the implementation of existing anti-plagiarism syst...
