2. document clustering techniques have been received more and more attentions as a fundamental and enabling tool for efficient organization, navigation, retrieval, and summarization of huge volumes of text documents . the aim of document clustering is to cluster the documents into different semantic classes in an unsupervised manner
   文本聚类作为一种对大规模文本信息进行有效地组织、导航、检索和概括汇总的关键的、基本的技术而日益受到关注,其主要目的是在语义空间里以无监督的方式将文本集中的文本划分成不同的类。
3. document clustering techniques have been received more and more attentions as a fundamental and enabling tool for efficient organization, navigation, retrieval, and summarization of huge volumes of text documents . the aim of document clustering technique is to cluster different documents into different semantic classes based on their content in an unsupervised manner
   文本聚类作为一种对大规模文本信息进行有效组织、导航、检索和概括汇总的基础、关键技术而日益受到关注,其主要目的是以无监督指导的方式根据文本的内在关系将内容近似的文本分成不同的类。
4. firstly, it presents the storing arithmetic based on the mapping policy between xml data modal and object-oriented modal . reference to the arithmetic of extracting object-oriented database schemas from xml dtds using inheritance and other commercial tools for xml storing, it improves mapping policy from xml to object, which optimizes the new semantic classes, what's more, it present object clustering policy to resolve the uncertainty of xml schema and the complexity of information intergration, which simultaneously focuses on the semanteme and structure of new object classes . on the other hand, it presents method to realize exchanging from object to xml
   本文研究构造基于xml信息集成系统结构的面向对象数据库包装器，提出面向对象数据库包装器的系统结构；根据该结构提出xml的数据模式与面向对象数据库对象数据模式的映射策略及相互存储转化算法，一方面我们借鉴基于dtd模式的继承对象映射提取算法及各种商业工具，提出dtd简化算法和基于dtd简化结构的对象图映射算法，优化了生成的对象类、提高了对象类的语义表达能力，也改进了对象映射提取策略；同时采用模糊聚类策略，提出对象聚类处理算法，改善了xml语义定义的随意性给对象类提取及信息集成带来的复杂性；另一方面本文提出对象到xml的转化算法，采用系统自动定义对象到xml的转化方法实现对象到xml的转化处理。
5. for each high frequency affix head, its morphological rules are automatically derived . the semantic types of their modifiers are obtained as the restriction on the rules for compounds . then the propriety of an unknown compound is estimated by the similarity measure between the semantic class of its morpheme and the semantic restriction posted in the respective rules
   我们以复合词为例，从语料库中，自动抽取各类复合词中的词干意类，用以训练规则，透过比对一未知词词干意类与规则意类间的相似度，判断其是否为合理的复合词。
