多年来，抄袭和相似性检测软件在大学里广为人知。尽管在抄袭检测中使用的方法和途径多种多样，但算法的速度和可靠性之间的典型权衡仍然存在。我们介绍了一种新的两步法来检测抄袭，该方法结合了高算法性能和成对文件比较的质量。我们的系统使用快速检测方法来只选择可疑文件，然后调用精确(和较慢的)算法来获得可靠的结果。我们的结果表明，该方法在提供更好的速度特性的同时，并没有显著降低两两比较机制的质量。
Plagiarism and similarity detection software is well-known in universities for years. Despite the variety of methods and approaches used in plagiarism detection, the typical trade-off between the speed and the reliability of the algorithm still remains. We introduce a new two-step approach to plagiarism detection that combines high algorithmic performance and the quality of pairwise file comparison. Our system uses fast detection method to select suspicious files only, and then invokes precise (and slower) algorithms to get reliable results. We show that the proposed method does not noticeably reduce the quality of the pairwise comparison mechanism while providing better speed characteristics.
