    随着信息技术的飞速发展,特别是互联网的发展,网络上的资源日渐丰富,获取信息也变得更加的方便和快捷,同时抄袭也变得更加的容易。使用文章比对系统能够实现对论文的自动比对,能够高效、快捷的帮助检测人员查找出存在抄袭嫌疑的文章。同时,在刊物审稿过程,实现文章比对能进一步提高编辑部的审稿速度与质量。并且文章比对还可以辅助鉴别文章内容的版权归属等不足。因此,对于文章比对的研究具有一定的实用价值和现实意 义。本文以粗糙集和粒计算理论为核心,研究中文文章比对的策略。首先,介绍了粗糙集理论、粒计算理论等基本知识,尤其是基于相容关系粒计算模型理论。讨论了粒计算的相关概念、中文分词技术、文本特点值提取,以及中文词语相似度计算等关键不足;其次,研究了基于相容粒计算模型的文章比对策略和设计了相应算法。给出文章相容粒、段落相容粒和粒空间信息表的定义,粒空间信息表的构建策略。根据粒计算理论中相容粒之间的外延关系和复合关系来计算文章相容粒之间和段落相容粒之间的相似度,并给出了示例说明。描述了基于相容粒计算模型的文章比对流程和提出了相应的算法;再次,在真实数据集下对所提出的算法进行不同方面的测试,并对测试结果进行的浅析浅析。测试结果和浅析浅析评估表明所提出的基于相容粒计算模型的文章比对策略是有效的,它基本能满足用户对相似性文章的查找需求。最后,对所研究的工作进行了总结和展望。将粗糙集和粒计算理论应用于文章比对中不仅扩展了理论在新领域的应用,而且为实现文章比提供了新的技术。

    【Abstract】WwW.zIdiR.coM With the rapid development of information technology, the development of Internet specially, the source of Internet is much more plenty day by day, and then it’s much more convenient to obtain information, at the same time it’s much easier to copy something from others. Article Comparing System is used to compare articles automatically, and help testing staffs to search the questionable articles effectively and rapidly. Meanwhile, in the process of editing, the method of article comparing can be used to improve the editing of speed and quality. Also, it can assist editor to distinguish the problem of copyright ownership and so on. Therefore, in term of the study of article comparing have some valuable of realistic and utility.The core concept of this paper is the theory of Rough Set and Granular Computing, the method of article comparing is researched. Firstly, the basic concept of RS and GrC theory is introduced, the theory of GrC model based on tolerance relation especially. Key problems, such as the concept of GrC, the technology of chinese segmentation, text feature extraction and similarity of chinese words, are discussed. Secondly, the method of article comparing based on tolerance granular computing model is researched, and relevant arithmetic is given. Including the definition and constructing method of article tolerance granule, paragraph tolerance granule and granule space information table. Meanwhile, according to relationship of extension and complex between the tolerance granules of GrC theory, the similarity degree of article tolerance granule and paragraph tolerance granule are computed, and examples are provided. The procedure and arithmetic of article comparing based on tolerance granular computing model are elaborated on. Again, with the real data set, the arithmetic is test in different aspects, and the experimental results are analysed. In term of the experimental result, the method of article comparing based on tolerance granular computing model is effective, and satisfied with the users’ requirement of finding similar articles basically. Finally, all of researches and work in the paper are summarized and prospected. The Application of Rough Set and Granular Computing in article comparing is not only extending the application of theory in the new field, but also provide a new technology for article comparing.
