Knowledge Management

Until comparatively recently, the value of a company was felt to be determined mainly by the value of its tangible assets. In recent years, however, it has been increasingly recognised that in the post-industrial era, an organisation's success is more dependent on its intellectual assets than on the value of its physical resources.This increasing importance of intangible assets is evidenced by the high premiums on today's stockmarkets. We can measure this by expressing the market value of a company as a percentage of its book value. Looking at this index, we see that the Dow Jones Industrial has risen steadily over the last 25 years and now stands at over 400%.Underlying this trend are a number of factors. The requirement for highly-skilled labour in many industries, new computing and telecommunications technologies, faster innovation and ever shorter product cycles, has caused a huge change in the ways organisations compete — knowledge is now the key battleground for competition.Other factors driving companies to try to manage and exploit their intellectual assets more effectively are increasing employee turnover rates and a more mobile workforce, which can lead to loss of knowledge, and globalization, often requiring people to collaborate and exchange knowledge across continents and time zones.The knowledge management discipline aims to address this challenge and can be broadly defined as the tools, techniques and processes for the most effective and efficient management of an organisation's intellectual assets [1].     

笔记本电脑的日常保养和维护

Concurrent Zero Knowledge, Revisited

We provide a more general and, in our eyes, simpler variant of Prabhakaran, Rosen and Sahai’s (FOCS ’02, pp. 366–375, 2002) analysis of the concurrent zero-knowledge simulation technique of Kilian and Petrank (STOC ’01, pp. 560–569, 2001).     

基于知识图谱的bug问题探索性搜索方法

软件bug问题在软件开发与维护过程中不可避免.然而软件历史库中的bug库与commit库之间没有直接的对应关系,并且随着bug信息、commit提交信息量的增长,搜索bug变得更加繁琐.本文提出一种基于知识图谱对bug问题进行探索性搜索的方法.通过建立bug报告、commit提交信息及相关人员（如：bug报告人、commit提交者等）信息的bug知识图谱,并结合探索性搜索的思想,不仅能准确搜索bug问题,还能提供相关辅助信息对bug问题进行探索性搜索,帮助软件开发人员更有效地理解和解决bug问题.     

Self-Interest Assumption and Relational Trust in University-Industry Knowledge Transfers

Since knowledge is a critical resource for ensuring firm growth and survival, firms are increasingly going outside their boundaries and collaborating with other organizations to obtain new knowledge. This study focuses on two distinct self-enforcing safeguards important for interorganizational knowledge transfer. Using survey questionnaire data from senior executives in 180 small to large-sized industrial firms working with university research centers, we focus on the self-enforcing safeguards of self-interest assumption and relational trust and examine the role of each in university-industry knowledge transfer. Results from multiple linear regression show both self-interest assumption and relational trust are positively associated with greater knowledge transfer, however, relational trust is more strongly associated to knowledge transfer than self-interest assumption. We also found that as knowledge becomes more tacit, self-interest assumption becomes negatively associated with knowledge transfer while relational trust becomes more strongly positive. We conclude by discussing implications for future research and management practice.

Knowledge representation and construction in hypermedia environments

Hypermedia information systems, because of their inherent qualities of nonlinearity and associative linking, offer the potential of facilitating enhanced knowledge representation and construction for users. These capabilities will be more fully realized if hypermedia information systems are developed and implemented based on constructivist learning theory. This paper examines the qualities of hypermedia systems that enable them to facilitate learning, discusses the background of current learning theories, and provides a brief view of a possible hypermedia system based on constructivist learning principles that could be developed through the use of intelligent autonomous agents.

基于知识图谱的泛在电力物联网安全可视化技术

随着泛在电力物联网的建设,电力网络向互联互通转变、数据向交互共享转变、业务向横向贯通转变,对原有网络安全防护体系提出了新的挑战。网络安全可视化技术通过对图模式的展示和分析,帮助网络安全人员快速识别潜在攻击,定位异常事件,发现新的攻击类型,快速捕获全局网络安全态势。基于知识图谱进行泛在电力物联网安全分析,通过对内外部威胁情报进行建模,构建概念实体间关系,将威胁情报知识图谱化,把复杂的警报信息转换成直观的、便于理解的图形图像信息,为泛在电力物联网的网络安全防护决策提供精准支撑。

Intelligent Knowledge Recommendation Methods for R&D Knowledge Portals

The personalization in knowledge portals and knowledge management systems is mainly performed based on users' explicitly specified categories and keywords. The explicit specification approach requires users' participation to start personalization services, and has limitation to adapt changes of users' preference. This paper suggests two implicit personalization approaches: automatic user category assignment method and automatic keyword profile generation method. The performances of the implicit personalization approaches are compared with traditional personalization approach using an Internet news site experiment. The result of the experiment shows that the suggested personalization approaches provide sufficient recommendation effectiveness with lessening users'unwanted involvement in personalization process.

基于Knowledge-Analysis的军事知识联通研究

军事专业知识在军事决策系统、军事智能教学系统、军事知识查询系统等高技术产品中具有重要的作用。知识库是机器智能的重要来源,所以有必要建立一个完善、协调、具有良好联通性的大型军事知识库,而大量实践证明计算机真正具有智能不仅需要大型知识库,而且更需要知识间广泛的联通。本文主要讨论军事概念联通。所谓概念联通是指通过关系链或属性或属性值将两个概念联系起来的过程。概念联通的目的之一就是通过概念联通帮助发现不同知识源的知识之间的不一致性,尽可能保证所获取知识的完备性和精确性,建立一个大型的军事专业知识库。
