Following researches on the knowledge-based product design, product modeling based on knowledge fusion is studied in a virtual environment. Knowledge fusion is the energy sources of product innovation designs. Because a knowledge representation method is the main content of knowledge fusion, production rule way, semantic network, predicate, object-oriented and case-based representations are discussed. Using agents with object-oriented method, the knowledge can be represented as a set. The product knowledge set is divided into two subset: text knowledge and knowledge of engineering graphics that is a different form. Manipulation of the subset knowledge and fusion method is described. The paper also describes a six-tuple function in an agent data structure. A virtual environment computation model is proposed, and a practical example given. 相似文献

A process-oriented knowledge-sharing platform is studied to improve knowledge sharing and project management of chemical engineering design enterprises. First, problems and characteristics of knowledge sharing in multi-projects of chemical engineering design are analyzed. Then based on theories of project management, process management, and knowledge management, a process-oriented knowledge-sharing platform is proposed. The platform has three characteristics: knowledge is divided into professional knowledge and project management knowledge; knowledge sharing is integrated with the project process, which makes knowledge sharing a necessary part of the project process and ensures the quantity of knowledge shared; the platform provides quantitative measurements of incentive mechanisms for knowledge providers and users which ensures the quality of knowledge shared. This knowledge-sharing platform uses two knowledge management tools, a knowledge map and a knowledge base, to support the platform. 相似文献

With the current trend that universities around the world have gradually stepped into higher education systems of popularization, there has been more diversity in universities; hence it has become necessary to increase the transparency of university governance. Since that university classification or university ranking is a powerful mechanism to demonstrate the diversity of an institute, the rankings of research funding have become desirable and also of great value. The main purpose of this study is to analyze the rankings of research funding among universities in Taiwan, and make relevant suggestions based on the findings. A secondary data analysis was conducted on the data obtained from the database of National Science Council, in order to develop the rankings of research funding among 164 universities in Taiwan. Based on the results, the conclusions are as follows: (1) The top three universities which won the funding of the National Science Council Research Project with the best overall strength were National Taiwan University, National Cheng Gung University, and National Chiao Tung University; (2) The top three universities which won the funding of the National Science Council Research Project with the best average faculty strength were National Tsing Hua University, National Chiao Tung University, and National Taiwan University. It is suggested that, when rating the strength of a university to win the research funding, both overall strength and average faculty strength should be considered to avoid the unfairness towards universities of smaller scale. 相似文献

The growth and evolution of the knowledge network in supply chain can be characterized by dynamic growth clustering and non-homogeneous degree distribution.The networks with the above characteristics are also known as scale-free networks.In this paper,the knowledge network model in supply chain is established,in which the preferential attachment mechanism based on the node strength is adopted to simulate the growth and evolution of the network.The nodes in the network have a certain preference in the choice of a knowledge partner.On the basis of the network model,the robustness of the three network models based on different preferential attachment strategies is investigated.The robustness is also referred to as tolerances when the nodes are subjected to random destruction and malicious damage.The simulation results of this study show that the improved network has higher connectivity and stability. 相似文献

The actual infrastructure of the information society sustains the globalization trend and increases the importance of the information and knowledge. The development of the knowledge society is the direct consequence of the mix of economic, social and cultural processes, which involve the knowledge creation and its equitable distribution, access and sharing. Universities, as poles of knowledge, creativity and innovation, play a key part in the regional development and the global competitiveness. The universities are active promoters of the innovation culture at the regional and international level, by increasing the synergy among education, research and innovation. The article focuses on the role of the academic area in the development of the learning and creative society at the regional level, contributing to the design of new knowledge and technology embedded products, services and organizational processes, which represent the premises of the global competitiveness. The most important challenge the academic environment faces in the new economy is to bridge the gap between the political decision, the governance and the labour market, offering innovative solutions and developing the intellectual capital to address the various issues of the knowledge economy. The article highlights the role of the universities as regional development drivers, by analyzing the economic performance of the Bucharest-llfov region and the direct influence of the trinomial equation: education-research-innovation. 相似文献

Background knowledge is important for data mining, especially in complicated situation. Ontological engineering is the successor of knowledge engineering. The sharable knowledge bases built on ontology can be used to provide background knowledge to direct the process of data mining. This paper gives a common introduction to the method and presents a practical analysis example using SVM (support vector machine) as the classifier. Gene Ontology and the accompanying annotations compose a big knowledge base, on which many researches have been carried out. Microarray dataset is the output of DNA chip. With the help of Gene Ontology we present a more elaborate analysis on microarray data than former researchers. The method can also be used in other fields with similar scenario. 相似文献

This paper describes some of the principles for building a freely available web-based university with open content. The "tutor-web" is an international project for web-assisted education, including such free and open access. This project was initiated by the University of Iceland in partnership with many universities around the world, among them the University of Craiova, Romania. The aim of this paper is to present this project, to point out its specificity and to arouse interest for collaboration in the project, which uses http://tutor-web.net as the home location. 相似文献

Language is closely related to culture. Language expresses and embodies cultural reality, in the meantime, culture exerts enormous influences on language. Therefore, language learning is often culture learning. The author, based on the negligence of culture teaching in English language classes, illustrates the influences of cultural knowledge on reading, translating and intercultural communicating, and proposes suggestions on culture teaching in English language teaching (ELT). 相似文献

Memorization has been long viewed as a bad practice or the opposite of meaningful learning.A survey on the role of memorization in ESL/EFL learning is carried out in Vestal Middle School,Binghamton High School and Binghamton University under the guidance of Professor Jennifer Brondell.The result shows that a majority of subjects were found to emphasize the important role of memorization as a strategy in helping students to obtain better accuracy and fluency,use language knowledge reserve,and gain more self-confidence. 相似文献
