A Source Code Similarity System for Plagiarism Detection

Source code plagiarism is an easy to do task, but very difficult to detect without proper tool support. Various source code similarity detection systems have been developed to help detect source code plagiarism. Those systems need to recognize a number of lexical and structural source code modifications. For example, by some structural modifications (e.g. modification of control structures, mod...

Evaluating the Performance of LSA for Source-code Plagiarism Detection

Latent Semantic Analysis (LSA) is an intelligent information retrieval technique that uses mathematical algorithms for analyzing large corpora of text and revealing the underlying semantic information of documents. LSA is a highly parameterized statistical method, and its effectiveness is driven by the setting of its parameters which are adjusted based on the task to which it is applied. This p...

A relentless pursuit of plagiarizing or the ineffective attempt to completely suppress all communication in the classroom are certainly as inadequate approaches as the installation of an offline plagiarism detection tool without a proper feedback mechanism for the ...

Normalization based Stop-Word approach to Source Code Plagiarism Detection

This paper is a report of PES Institute of Technology’s participation in the Cross Language Detection of Source Code Reuse (CL-SOCO) task at FIRE 2015 [1]. We approach this task as text document plagiarism task, without considering formal programming language grammatical structure. We use normalization of commonly used identifiers to detect pair of programs which have the same objective. We als...
