Using Microsoft SQL Server platform for plagiarism detection

The paper presents an approach for plagiarism detection using Microsoft SQL Server platform in a large corpus of documents. The approach was used for participation in the first international plagiarism detection competition that was held as a part of PAN’09 workshop. The main advantages of the proposed approach are its high precision, good performance and readiness for deployment into a production environment with relatively low cost of the required third party software. The approach uses fingerprinting-based algorithm to compare documents and Levenstein’s metric to markup plagiarized fragments in the texts.
