Text Reuse and Plagiarism Detection

With ever more electronic text being created by word processors and ever wider access to electronic text via the Internet, wider incidence of plagiarism was inevitable and is now occurring. Higher education institutions charged on the one hand with embracing new technology and widening access through increased participation and use of distance learning, and on the other hand with maintaining quality and standards, need tools to help combat this form of fraud. Computerised techniques that analyse lexical and phrasal features of texts can help to identify likely incidents of plagiarism and draw tutors attention to texts that should be more closely examined to determine whether plagiarism has or has not occurred.

This project will develop new techniques for automatically identifying text reuse and plagiarism. Several different types of text reuse (and plagiarism) can occur, for example when the original document has been translated from another language or rewritten to avoid detection. The project will focus on a subset of these types.
