A Student plagiarism is an ever-increasing problem for academic institutions. A growing number of students are using material from the Web in their submissions, without properly acknowledging the source. This paper reviews the need for wide spread plagiarism detection systems and evaluates available Web based detection services. Four services are discussed: the Measure of Software Similarity (MOSS) service for program source code and the, Integriguard and services for free-text submissions. The downloadable Essay Verification Engine (EVE) tool for free-text detection of Web plagiarism is also evaluated. The paper finds that all five could be invaluable resources for academic institutions as they strive for a pro-active anti-plagiarism policy. The paper concludes by looking at the authors’ current work to combat plagiarism.

According to Teacher Courses in Mumbai Plagiarism in the sense of “theft of intellectual property” has been around for as long as humans have produced work of art and research. However, easy access to the Web, large databases, and telecommunication in general, has turned plagiarism into a serious problem for publishers, researchers and educational institutions. In this paper, we concentrate on textual plagiarism as opposed to plagiarism in music, paintings, pictures, maps, technical drawings, etc. We first discuss the complex general setting, then report on some results of plagiarism detection software and finally draw attention to the fact that any serious investigation of value to all researchers, educators and students in plagiarism turns up rather unexpected side-effects. There are many definitions of what constitutes plagiarism, and we below. However, according to research resources at, the things that will look at some of them in more detail immediately come to mind as description of plagiarism are:

  • turning in someone else’s work as your own
  • copying words or ideas from someone else without giving credit
  • failing to put a quotation in quotation marks
  • giving incorrect information about the source of a quotation
  • changing words but copying the sentence structure of a source without giving credit the sentence structure of a source without giving credit
  • In some areas law a scholarly paper may well Consist of a conjecture followed by hundreds of quotes from other sources to verify or falsify the thesis. In such case, any attempt to classify something as plagiarized vs. not-plagiarized just based on a Count of lines of words that are taken literally from other sources is bound to fail. In other areas like in a paper in ma it may be necessary to quote standard literature just to make sure that readers have enough background to understand the important part, the proof of a new result whose length may well be below one third of the paper. In other disciplines like engineering or computer science the real value of contribution may be in the device or algorithm developed that may not even be explicitly included in the paper rather than the description of why the device or algorithm is important that may well be spelled out in a number of text books. In this summary we believe that there is no valid definition of even textual plagiarism that is not somewhat domain dependent, complicating the issue tremendously.
