按知识流失度可将知识分类成易流失知识和常识性知识.这对组织具有重要意义,也是知识管理的一个重要研究内容.本文从定量的角度出发,提出用超网络模型计算知识流失度,再根据这个客观指标对组织知识进行分类.先按照不同类型的数据,分别建立人员网络、物质载体网络和知识网络,再根据各个网络间的关系构建超网络模型.在超网络中,首先依据知识网络与人员网络之间的关系计算出知识流失度,然后依据知识流失度对组织知识进行分类.在此基础上,又将组织知识的领域划分成易流失领域和常识性领域.最后给出一个实例对构建的模型和方法进行了验证. 相似文献

维基百科分类页面所构成是一种在用户自发的协同编辑行为下建立起来的、具备自组织特性的全新知识分类结构。依据维基百科分类结构特点,将其看成是以分类页面为领域知识节点,以节点间相互包含关系为边的领域知识分类结构。采用自回避随机游走方法(self-avoiding random walks)构建领域知识节点熵测量模型,从而测定领域知识结构中心领域知识和边缘领域知识节点,以研究领域知识节点随时间演化的规律。研究表明,大多数情况下,多样性熵值越大的节点,越趋向于知识结构的中心领域知识,且其创建的时间也越长;处于相同社团结构中的节点间存在关联关系,使得它们的多样性熵值表现出相似的变化趋势。 相似文献

In the business world, electronic mail (e-mail) has emerged as a widely used communication tool for transmitting knowledge between managers. As a result, these messages will require organization should future access to this trapped knowledge be expected and desired. A manager's e-mail classification scheme should be logically constructed in anticipation of future need, but future need may be driven by the information needs of other people within the organization such as superiors or subordinates. This researcher explored the nature of e-mail classification and documented the emergence of a high utility, multi-stage, classification process. The resulting framework consists of four categories that help explain how managers classify business-related e-mail. The first category reflects the immediate needs of the manager and the behavior of establishing relationships between messages. The second category reflects the manager's use of the in-box as a crude task-manager. The third category aligns with the manager's interest in scanning the environment. The fourth category reflects the managers perceived future need for the captured knowledge. The subjects rejected automatic classification and preferred an enumerative scheme. The researcher illustrates how the results of this study align with Marco and Navarro's three stage cognitive process that leads to stored knowledge (On some contributions of the cognitive sciences and epistemology to a theory of classification, Knowledge Organization, 20(3), 126–132). The cognitive processes that underlie classification are an essential component in understanding knowledge organization and have remained in focus during this study. 相似文献

AbstractShifting library catalogs from physical to digital has come at a cost. Catalog records no longer leave traces of their own evolution, which is a loss for librarianship. The subjective nature of information classification warrants self-examination, within which we may see the evolution of practice, debates over attribution and relevance, and how culture is reflected in the systems used to describe it. Wikipedia models what is possible: revision histories and discussion pages function as knowledge generators. A list of unanswerable questions for the modern catalog urges us to construct a new, forward-thinking bibliography that allows us to look backward. 相似文献

This article describes a method that academic librarians can use to help established scholars and doctoral students become more cognizant of interdisciplinary approaches to their academic fields and areas. This method centers around the creation of knowledge maps: visually oriented aids tracing intellectual connections and linkages between and among various fields and areas that allow students and professors to get a good sense of emerging trends in a given academic specialty. Many professors want librarians to be proactive when it comes to suggesting new perspectives and new ways of seeing their research questions. Knowledge maps can be used by librarians as information-literacy tools in the facilitation of interdisciplinary knowledge among academic researchers. In addition, the creation of knowledge maps by librarians can be seen as a component of the changing nature of reference librarianship—a job that is becoming more intellectualized through one-on-one consultations between students, professors, and librarians. 相似文献

本文旨在为国内外分类法拥有者快速实现现有分类法的Web版、Web Service术语服务、Linked Data化和自动分类等网络共享服务提供参考和支持。以《中国图书馆分类法》第四版为例,采用CNKOS对分类法进行语义化描述,使用Lucene全文检索引擎、Ext Js插件、Axis SOAP引擎和URL Rewrite等关键技术实现了分类法共享服务(CLSS)原型系统。经验证明所有功能模块运行和调用都符合预期效果。实践证明该套解决方案可投入使用,而且其他分类法类型的中文知识组织系统均可依此方法快速完成相应的部署。但是,对于部分复杂的自动分类需求,如要获得更为准确的分类号还需更深入的研究或人工辅助。图5。表4。参考文献21。 相似文献

This study examines recently reformed classification frameworks in the United Kingdom, Australia, and New Zealand to better understand the changing nature of administrative secrecy. The analysis investigates and compares the drivers and outcomes of these classification reforms. While these case countries largely share incentives for and objectives of reform, they do not develop a uniform approach to restructuring their classification frameworks. Further, their reform processes vary, from incremental reforms in Australia to a more sweeping revamp of the UK's classification system. Overall, reform efforts point to a trend of increased simplification and proactive risk management. The classification frameworks in case countries have moved away from a dichotomous understanding of secrecy and transparency toward a gradient logic embedded within broader considerations regarding information management, exploitation and sharing. 相似文献
