Workflow is used as the information carrier and delivers task related information along with process flow . users can send information search requests to information search unit with the help of information search client to get the needed information in an efficient and precise way . ( 3 ) some key technologies for enterprise workflow information active sharing based on the proposed system framework , the detailed study on the key technologies of enterprise workflow information active sharing have been made : a directed graph based new workflow modeling method is proposed 该结构采用企业信息索引为系统自动化的信息检索提供支持；企业信息检索机构负责对信息需求进行处理，推动企业信息检索过程，并响应人工推动的企业信息检索请求；以工作流为载体，在过程的自动化推进中主动传递任务所需信息，并通过信息检索客户端向信息检索机构发出检索请求来高效、准确地取得系统无法主动提供的任务所需信息。
With new system , the user can define multiple " region of interest " and can specify the relevance of their spatial layout in the retrieval process . the methods often do succeed in capturing higher - level knowledge about what exactly was of interest to the user in the query image ; consequently reduce the blindness of retrieval 本文在此原则的基础上给出了新的图像检索系统的设计与实现方案，新系统下用户能够自定义多个“感兴趣区域”并且在检索过程中指定它们的空间布局相关性，查询区域的自定义方式使系统可以部分的获得用户查询的高层需求，从而降低了查询的盲目性，提高了效率。
This paper in turn introduces correlative knowledge on case description and a object oriented representation , the aim , tenet of casebase organizing and index and a organizing and index method using dynamic clustering , several typical case retrieval methods , the acquirement of adjustment knowledge , the classification of adjustment methods and a transform adjustment model , evaluate method of new case and learning and maintenance of casebase etc . moreover this paper also stressed discusses two central problem in case retrieval : the setting of property weight and the assignment of local similar degree between property values 本文依次介绍了案例表示的相关知识及一种面向对象的表示方法，案例库组织索引的目标、原则及采用动态聚类进行组织索引的方法，几种典型的案例检索方法，案例调整知识的获取、调整方法的分类及一个转换式调整模型，新案例的评估方法及案例库的学习与维护等。此外，对于案例检索过程中的两个重要问题，属性权重的设置和属性值间局部相似度的赋值问题作了重点讨论。
Then after summarizing the development of bill - of - material system , the generic bill - of - material was used to representing the product family structure for mass customization . the configuration model based on the gbom and cbr was established under the direction of the independence of product model and configuration . and the process of case indexed was described from the point of view of the disassembling product function and product structure 首先综述面向大规模定制的产品设计技术( designformasscustomization ， dfmc )的理论基础，在探讨产品结构化方法发展过程的基础上，确定创成式bom方法为mc模式下产品族结构的描述方法；然后分析了产品配置的原理及配置器的推理方法，在产品模型与配置器分离思想的指导下，提出了适用于mc模式的基于gbom和cbr的产品配置方法，并从产品功能分解和产品结构分解的角度描述了实例检索过程。
Secondly , the core conception of cognitive towards information science is " human as essence " , and bring forward that the information system is one that can boost up and magnify the existence value , ability and specialty of " human " , and provide users a system which is active and unforced , rather than force users to arduously adapt system . thirdly , from the visual angle of cognitive , information - seeking or information - using is a kind of cognitive behavior in essence . fourthly , cognitive style is the development trend of future information retrieve system , it can reveal the thinking - process of users during retrieving on - line , in order to help users to develop their knowledge configuration 首先，认知观可集成情报科学的相关领域，从而为形成统一、有效的情报科学提供体系结构；第二，情报学认知观把“以人为本”作为它的核心观念，提出情报系统设计的任务是要设计出增强和放大“人”的存在价值、能力和特长的系统，使提供给用户的情报系统是一种积极自然，而不是要求他们花力气去适应的系统；第三，从认知角度来看，情报查寻和利用从根本上说是一项认知行为；第四，认知风格将是未来情报检索系统的发展趋势，这样可以揭示联机检索过程中的用户思维过程，以便有助于用户知识的发展；第五，知识的进化与认知活动有密切关系，人的知识结构对外来信息的吸附、同化、选择、建构和实现社会化的过程，其实就是知识的进化；第六， “知识结构”将成为情报学认知观研究的重点。
