In this paper , one kind of chaotic - sequence - based text digital watermarking technology in light of the characteristics of text is put forward which can be used to protect the digital - text - related copyrights 摘要针对文本的特点提出了基于混沌序列的文本数字水印技术，并通过实验验证了该水印技术的实用性。
Based on the careful analysis of present clustering algorithm , we give two text clustering algorithms : ek ( exact k - means algorithm ) and dbtc ( density - based text clustering ) , and discuss the results of clustering experiments 对现有聚类算法进行了仔细分析，给出了两个文本聚类算法： ek算法和dbtc算法。对这两种算法进行了详细介绍，并分析了聚类实验的结果。
However , instead of simply scanning for page - based text which can be manipulated by site publishers through meta - tags , google s technology analyzes the full content of a page and factors in fonts , subdivisions and the precise location of each word 但是， google并非只是简单地扫描网页文字网站出版者可透过中继标记操控这些文字， google的技术会分析网页的完整内容，以及字型分支和每个字词的确切位置等因素。
Nevertheless , the underlying electron - specimen interactions are common to many techniques and in view of the fact that a range of hybrid instruments is now available it seems appropriate to provide a broad - based text for users of these electron beam facilities 但是，电子样本互动的依据与许多技术类似，并且，事实所表现的是，为这些电子束设备的使用者提供广泛的文本看来似乎也是可行的，一部分混合工具也出现了。
The original tcp / ip protocol suites were developed for narrow band based text data . with the flourish development of the global internet , the demands for better network performance are increasing , and the conflicts caused by tcp / ip layered architecture are emerging 最初的tcp / ip协议栈本来是为了窄带文本数据而开发的,但是随着全球互联网的蓬勃发展,人们对网络的利用和依赖的增加,各种新的网络服务不断涌现,从而对网络的性能提出了更高的要求。
Content - based text management is one of them . and the text classification is the foundation of content - based text management . so text classification is researched on three levels : the theoretical , the technological and the application level and it is used to solve some problems in the information retrieval , management and gathering in " chinese american digital academy library ( cadal ) " and " chinese scientific digital library ( csdl ) " - projects 笔者认为原因之一是现有的信息系统还没有能够对信息资源进行有效的组织管理，解决此问题的途径很多，内容管理是其中之一，而文本分类则是所有基于内容的文本信息管理的基础，因此笔者在参与“中美百万册书数字图书馆” 、 “国家科学数字图书馆”等研究项目的同时，从理论、技术和实践三个方面对文本分类进行了深入的探讨，并采用文本分类技术来辅助解决了信息系统建设中资源服务、管理和采集方面的一些问题。
