摘要

文档内容的部分或全部复制在大型数字图书馆中很常见。提出了一种副本检测系统,用于自动检测数字文档中的应用程序。我们提出的系统是基于句子的,它做出了三个贡献:它提出了文档之间相似度的直观定义;它产生重叠文档之间存在的重叠分布;它可以抵抗由于文档大小的巨大变化而导致的不准确性。我们报告了几个实验的结果,说明了系统的行为和功能。

Copy detection systems for digital documents
Partial or total duplication of document content is common to large digital libraries. We present a copy detection system to automate the detection of application in digital documents. The system we present is sentence-based and makes three contributions: it proposes an intuitive definition of similarity between documents; it produces the distribution of overlap that exists between overlapping documents; it is resistant to inaccuracy due to large variations in document size. We report the results of several experiments that illustrate the behavior and functionality of the system.
