Similarities and writing style features are computed with the help of predefined document models and might represent false positives. PDSes are not capable of reliably identifying plagiarism without human judgment. This approach aims to recognize changes in the unique writing style of an author as an indicator for potential plagiarism. Intrinsic PDSes solely analyze the text to be evaluated without performing comparisons to external documents. īased on a chosen document model and predefined similarity criteria, the detection task is to retrieve all documents that contain text that is similar to a degree above a chosen threshold to text in the suspicious document. Įxternal detection systems compare a suspicious document with a reference collection, which is a set of documents assumed to be genuine. Systems for text similarity detection implement one of two generic detection approaches, one being external, the other being intrinsic. A 2019 systematic literature review presents an overview of state-of-the-art plagiarism detection methods. Software-assisted plagiarism detection Ĭomputer-assisted plagiarism detection (CaPD) is an Information retrieval (IR) task supported by specialized IR systems, which is referred to as a plagiarism detection system (PDS) or document similarity detection system. TMS does not actually detect plagiarism per se, but instead finds specific passages of text in one document that match text in another document. Text-matching software (TMS), which is also referred to as 'plagiarism detection software' or 'anti-plagiarism' software, has become widely available, in the form of both commercially available products as well as open-source software. This can be a lengthy and time-consuming task for the reader and can also result in inconsistencies in how plagiarism is identified within an organization. Human detection is the most traditional form of identifying plagiarism from written work. ĭetection of plagiarism can be undertaken in a variety of ways. The widespread use of computers and the advent of the Internet have made it easier to plagiarize the work of others. Plagiarism detection or content similarity detection is the process of locating instances of plagiarism or copyright infringement within a work or document.
