Combing the available iir technologies , we designed a comprehensive contend - based iir system with friendly interface for users , which implemented metadata retrieval , text retrieval and vision - based retrieval . this system offers an effective and efficient retrieval mechanism for the army to study all the available weapons and equipments with military images 最后综合以上技术,设计实现了一个综合的基于内容的图像检索系统,集成了元数据检索、全文检索、基于视觉特征检索等多种检索方法,为用户提供了友好的使用界面,本系统为军队使用军事图片研究各种武器装备的性能提供了一种有效的检索机制,大大提高了检索效率。
The article does some research of the full text retrieval technology . 1 、 the article summarize the development of the web search technology in the domestic country and aboard . it will refer to not only the common document retrieval in the web , but also the query of concept information , hypertext information , multimedia information and the data mining 本文对全文检索技术进行了以下几方面的研究: 1 、介绍了国内外检索技术的发展过程,讨论了普通文本检索、概念信息检索、超文本信息检索、多媒体信息检索、数据挖掘等的技术特点。
Automatic texts classification is an intelligent technology of information processing , and the foundation of text retrieval , which applied to news categorization , electronic conference , e - mail categorization and information filtering etc . automatic texts classification plays an important role in traditional intelligence retrieval , foundation of web index architecture , web information retrieval , and so on 文本数据分类是一项重要的智能信息处理技术,是文本检索技术的基础,在新闻机构分类、电子会议、电子邮件自动分类和信息过滤等方面极具应用价值。文本数据分类在传统的情报检索、网站索引体系结构的建立和web信息检索等方面也占有重要地位。
There are two kinds of retrieval model , full text retrieval and content retrieval , and the vector space model ( vcm ) of the latter is a widely - used method with better effect . the best excellence of vcm is the predominance of knowledge presentation , which expresses documents with vectors in vector space and changes the comparability issue to the distance of vectors , and thus reduces the complexity of documents matching . however . we can not affirm the absolute effect of it , and in this thesis we prove its nonproficiency through experiments 向量空间模型最大的优点在于知识表示方法上的巨大优势,用n维空间的向量表示文档,用向量之间的夹角表示文档的相似度,从而将文档信息的匹配问题转化为向量空间中的矢量匹配问题,将难以计算的文字量化成很容易计算的实数,使问题的复杂性大大减小。但是,并不能够说目前的向量空间模型是最理想的,本文通过实验证明了vcm表达信息的不精确性。
The software bases on unicode and cjk + which included chinese , japanese and korean characters and can run well on multilingual windows systems ( include simplified chinese , traditional chinese , japanese , korean and english ) only with single data and single binary . e - sibucongkan ' s server provides powerful full - text retrieval engine and simplified / traditional / variant chinese characters association or hyperlink for retrieval and checking 0 )和中、日、韩汉字大字符集文字平台C J K的基础上,经过切分、 ocr 、软件校对处理,使一套数据一套软件,能够运行于多文种视窗平台(即在中文简体、中文繁体、日文、韩文和英文等不同视窗平台运行同一数据和软件) 。
