New plagiarism detection system to clamp down on thieves and cheats
Tuesday 26 July 2011
IP theft has been characterised as a £9.2 billion problem in the UK alone that is “greatly assisted by an ‘insider’” according to a recent report from Detica, a specialist security firm which is part of BAE Systems, and Cabinet Office.
The detection of leaked Intellectual Property presents an interesting challenge because you’d want to be able to search for things without revealing the set of queries that you want to use.
The plagiarism detection task, running for a third year as part of the 5th International Workshop on Uncovering Plagiarism, Authorship, and Social Software Misuse (PAN'11), involves identifying the precise extent of passages plagiarized from source documents and inserted into other documents either as they are or with some attempts made to modify the plagiarised text.
This task, referred to as external detection, involves both source and suspicious documents being provided, with last year’s competition involving the search for some 68,558 plagiarism cases across 27,073 documents.
Dr Lee Gillam, Lecturer in the Department of Computing, said: “Our aim in undertaking the competition was to show that the novel approach being employed by Surrey could cope quickly with the volume of competition data, which itself provides a challenge to other competitors, and still attain very competitive detection performance.”
