Moreover , the design procedure , workflow , usage approach , running conditions of the system are detailed . according to the trend of integration of classifications and thesauri , the paper also designed keyword retrieval system , directory search system , and integrated system individually 根据分类主题一体化发展方向，本文还设计了检索型、目录型及分类主题一体化检索系统，并提出基于集成词表的不同引擎间类目体系的兼容互换方案。
This paper elaborates two mistaken domains in application of general problem classes in chinese library classification , points out that general problem classes themselves are not available for classifying , the paper also provides the rule of adding " 0 " in application of general problem classes 摘要论文分析了《中图法》 “一般性问题”类目使用中的两大误区，提出“一般性问题”为非使用类目，不能直接用于类分文献；论文同时还阐明了在类目跨越仿分后，再仿“一般性问题”分时的加“ 0 ”规则。
We analyzed the regular pattern of daily medicine cost change of operation inpatients during hospitalization in every group . the results indicated that the median line of daily medicine cost had similar regular pattern in operations on the nervous system , the musculoskeletal system , the nose , mouth , and pharynx system and the female genital organs system : the top of daily medicine cost median emerged on the day of operations ; the median of daily medicine cost was low in the period after operation , and the lowest in the period before operation . the median line of daily medicine cost of operations on the digestive system and the integumentary system keeped at a high level in the period of 1 - 6 days after operations 手术病人日药费随住院时间的变化规律按icd - 9 - cm类目表的15个系统大类（解剖学分类）将住院手术病人分为15组，分析了各系统手术病人住院期间日药品费用的变化规律，结果显示：神经系统、肌肉骨骼系统、鼻口咽系统和女性生殖系统手术的日药费中位数线图具有相似的变化规律：手术病人住院期间的日药费硕士学位论文中位数的峰值位于手术当日，且手术当日的日药费变异最大；术后住院日的日药费中位数明显降低；术前住院日的日药费中位数很低；消化系统和体被系统手术在手术当日及术后1 6天内的日药费中位数维持在较高的水平。
A method that combines category - based and keyword - based concepts for a better information retrieval system is introduced . to improve document clustering , a document similarity measure based on cosine vector and keywords frequency in documents is proposed , but also with an input ontology . the ontology is domain specific and includes a list of keywords organized by degree of importance to the categories of the ontology , and by means of semantic knowledge , the ontology can improve the effects of document similarity measure and feedback of information retrieval systems . two approaches to evaluating the performance of this similarity measure and the comparison with standard cosine vector similarity measure are also described 介绍了一种综合各层级分类类目和对应关键词来构造概念体系并用于改进信息检索系统效果的方法.为了改进文本聚类的效果,提出了将领域知识本体和文本关键词词频相结合的基于余弦向量的文本相似性测度方法.该本体面向特定领域,将关键词以不同权值对应于各分类类目,通过其语义知识来改进文本相似性测度以及信息检索系统的效果.进一步给出了对基于本体的相似性测度方法进行效果评价的2种策略以及该方法与经典余弦向量测度方法的比较结果
Their common aim is to acquire knowledge , magnify character and form perfect personality . finally , the article investigates the history of practical observation on teacher - student interaction in class , which mainly comes form european , american and chinese scholars " relative practical observation , such as the teacher - students observational detailed item list designed by gallon . w , the small community interaction item system constructed by bales . r . f , the subject constituent of teacher - student intercourse in class constructing and the observational detailed item list to the teachers and students " individual language interaction by wu kang - ning , and the observational detailed item list to the teachers and students " spoken language interactive behavior in class by shen gui - peng . the most influenced one is the interaction category analysis system by flanders . n . a , whose important devotion is the observational category system to teachers and students " language and silence and the relative observational detailed item list 这主要涉及欧美、中国学者的相关实证研究，主要包括高尔顿( galton , w . )等人设计的对教师、学生的观察项目清单、贝尔斯( bales , r . f . )建构的小群体互动行为类目系统、吴康宁等人的课堂教学师生交往的主体构成、师生个体言语交往行为观察清单及沈贵鹏等人的“教师课堂口头言语互动行为”的观察项目清单等，但最具影响力的是弗兰德斯( flanders , n . a . )的互动分类分析体系，弗兰德斯的主要贡献是设计出了教师的语言、学生的语言及沉默等观察类目系统及相应的观察类目清单。
( 3 ) eco - tourism value of wetland landscape resources . for a rational development and protection of the wetland , we studied its landscape resources and its value to created an assessment system of the ecological landscapes , and to evaluated qualitatively and quantitatively the value of wetland to the eco - tourism . we also analyzed the structure , classification and order of the wetland landscapes 同时，根据ahp 、多元分析及数量化理论，科学地提出了南洞庭湖景观生态数字化评价模式，筛选了湿地景观九个因子，制定了景观因子等级标准体系，建立了湿地景观项目( 9 ) -类目( 34 )系统，完成了86个景观样本景观因子的数字化。
Taking managers in enterpri ; e as participants , this research has collected data via interviews , open questions , importance hierai : hical evaluation as well as close questionnaires of the behavior types and of hierarchica evaluativn . forecast analyses and item modification of the questionnaires have been conducted from vari < us angles in terms of factors analyses , test factors analyses , relationship analyses , diligence cst and item analyses to secure a high reliability and validity . then the law of inner factors and he functions on management performa 本项研究以企业管理者为被试，综合运用访谈法、开放性问卷法、重要性等级评定法和封闭式问卷法收集资料，编制了典型管理沟通情境下行为反应类目迫选问卷和等级评定问卷，并采用探索性因素分析、验证性因素分析、相关分析、差异检验、项目分析等多种统计方法，从多角度对问卷进行了预测、项目修改，使正式问卷取得较好的信度和效度。
In the " trec 2002 text filtering compete " , the difference between normal subjects and combine subjects are compared and how to use the text classification technologies into the filtering system is also explained . from the system , we can get the conclusion that only when a system has considered all the related factors in the text classification system , can it get a fine results 在“ 2002年trec文本过滤比赛”案例中，对比了一般类目和组合类目在文本过滤中的不同之处，并通过此案例说明了如何将文本分类技术研究中的成果应用在实际文本过滤系统当中，并得到如下结论：只有将文本分类系统的各方面技术进行综合考虑，才能够最终取得更好的分类效果。
