Three Way Search Engine Queries with Multi-feature Document Comparison for Plagiarism Detection
Original language description
In this paper, we describe our approach at the PAN 2012 plagiarism detection competition. Our candidate retrieval system is based on extraction of three different types of Web queries with narrowing their execution by skipping certain passages of an input document. We have created queries based on keywords extraction, intrinsic plagiarism detection and headers extraction. We have also compared the performance of constructed queries used during the PAN 2012 test process. The proposed methodology was thebest performing one in case of long term operation and also the most cost-effective one. Our detailed comparison system is based on detecting common features of several types (in the final submission, we have used two types of features: sorted word 5-grams and unsorted stop word 8-grams) in the input document pair. We propose a method of computing so called valid intervals from those features, represented by their offset and length attributes in both source and suspicious document.
