摘要：
文档复制检测技术在保护知识产权和信息索引中起重要作用,它可以防止剽窃事件的发生,提高互联网检索效率。目前,英文复制检测技术已经比较成熟,但中文复制检测技术研 究还处于起步阶段。本文提出一种基于关键词的指纹提取方法;提出k-words方法分解句子;定义了数字指纹树概念,并用数字指纹树来存储指纹。最后,用实验验证了所提出的 方法。
关键词: 指纹 剽窃 文本块 匹配
Abstract:
The technique of copy detection plays an important role in intellectual property proteetion and information retrieval, whieh can prevent plagiarism and improve the retrieval effieieney of the Internet.
