Secondly , we analyse general criteria of data classification , the definition and representation method of conceptual hierarchy , and criteria of evaluating classification scheme . according to the analysis , we briefly provede the architecture of data classifier 而后，分析了数据分类的一般标准、概念层次的定义和表示方法、评价分类模式的标准等问题，并给出了数据分类器的结构框架。
In the implementation of data classifier , we describe extraction and management of conceptual hierarchy for data , also design an automatic extraction algorithm for numeric data . in this section , we still provide the two algorithms of concept - based attribute - oriented induction and evaluating classification scheme and the visualization of classification rule . finally , the data classifier is tested in databas the results show that it is practical and its performance meet the requirement of designing 然后，在数据分类器的实现中，论述了数据的概念层次提取和管理，并对数值型数据给出了一个自动提取概念层次算法；同时给出了基于面向属性归纳的分类算法、分类模式的评价算法和分类规则的可视化方法。
First , a model of automatic text classification system is described , which includes five aspects : the information pretreatment 、 the features denotation 、 the features extraction 、 making use of text mining technique extracting classified model ( involve text clustering and classification ) and evaluating model quantity 论文首先阐述了文本分类器的总体模型，包括：信息预处理、特征表示、特征提取、利用文本挖掘技术提取分类模式（其中涉及到文本聚类、分类）和对模式进行质量评估等五个方面。
Therefore it can support the reuse of higher level of gis component . aiming at the two key technology in gis rcl ? ? classification and searching , the paper discussed emphatically : based on the faceted classification scheme , gis ' s spatial geographic speciality , the integrating speciality of spatial attribute and non - spatial attribute , and requirement of interaction , the paper introduces gis components " classification system . the faceted classification scheme is < level , function , object , style > 论文针对gis组件库的两个关键技术? ?分类和查询进行了重点讨论：基于组件刻面分类策略并结合gis的空间地理特性和空间属性与非空间属性相结合的特性和对互操作的需求建立了适合gis要求的gis组件分类体系，对gis组件提出了<层次、功能，对象，格式>的刻面分类模式。
Moreover , for chinese banks and researchers , both the requisite technologies and experiences in this field are just in the beginning steps , yet somewhat lagged behind . the main purpose of this paper is to give a complete and systematic discussion on the theoretic basis , methods and formalities of the five - class system of credit assets , which is currently used in the people ' s bank of china , together with the introduction and comparison of other contemporary formalities of credit assets adopted by other commercial banks . then we give a deep and concrete analysis of the situation and problems in the current operation of the credit assets five - class system in the b city commercial bank in anhui province 本文的主要目的就是针对目前中国人民银行正在推行的信贷资产五级分类的理论基础、方法及程序进行了较为全面和系统的论述,并对同时期国内外商业银行所采取的信贷资产分类模式做了相应的介绍和比较,进而具体剖析了现阶段安徽省b市商业银行在信贷资产五级分类操作中的具体步骤,同时,借鉴了贷款风险评估的相关理论和模型,对安徽省b市商业银行目前的贷款风险分类方法的现状和存在的问题进行了较为深入的、系统的分析。
This paper analyzed shaman ' s identity of communication with spirit from an angle of structural classification , or alternative classification , confirming that the people in the tribe born unconventionally or that who can self - cured from the disease were thought as shaman with identity of communication with spirit , which was a necessary supplement to dualism in classification of levi - strauss 本文从结构主义分类学的角度对萨满通灵身份进行分析，或者通过“另类”分类模式，认定部落中出生异常或有病自愈的人，为具有通灵身份的萨满，这种分类法是对列维?斯特劳斯二元分类法的一个必要补充。
The research on website retrieval will be benefited from the solution of subject analysis , index and retrieval put forward in this thesis . it can avoid the conflict between multi - needs of user and the single - structure of categorization , while overcame some questions that may appear in the traditional information retrieval mode and can offer a series of particular themes tracing and searching service 本文提出的网站主题分析、标引与检索技术为网站检索提供了新的解决方案,提供了更适于传统信息检索模型与用户检索习惯的标引技术,使之避免了传统分类问题中构建类别体系的单一性与用户需求的多样性之间的矛盾,克服了传统信息检索与分类模式中可能出现的部分问题,可以提供一系列特定主题的跟踪、检索服务。
