构筑信息服务保障体系思实录 总被引：2，自引：0，他引：2
Combining theory with practice and proceeding from operability, this paper puts forward 7 principles of con-structing the information service guarantee system, that is, engineering, capability, mutual service, service advantages,Web-besed information, overall coordination and sustained perfection. Meanwhile, the paper poirts out that, in the con-stmcfion and operation of the information service guarantee system, the interrelationship of key elements is more important than the constitution of key elements, and the construction of the system is more important than the application of technology. 相似文献

Based on the concept of genetics, this article studies the phenomenon of information communication and the characteristics of information itself. It points out that the comparability between genetics and information science is the basis of putting forward the concept of information DNA. Through a discussion on the application of some laws of genetics in information science research, this article demomtrates the rationality of putting forward the concept of information DNA. 相似文献

The paper discusses the orientation of knowledge management in enterprises, a problem often neglected by the theoretical circles in the study of knowledge management. It points out that enterprise knowledge management is not exactly equal to knowledge management in theory, the former is only a branch of the latter. However, they are equally and alternatively used in practical applications as enterprise knowledge management is developing most rapidly and has the greatest influence. Therefore, the orientation of enterprise knowledge management is obscure. 相似文献

论自然语言检索 总被引：8，自引：1，他引：8
With its advantages in information retrieval, such as simple in indexing and convenient in information re-trieval, natural language is now widely used in idonnafion retrieval and network retrieval. However, due to some charac-teristics of the natural language itself, its retrieval result is usually tmsafisfactory. This paper sumamrizes several main fac-tots that restrict natural language retrieval and introduces a concept space method to improve its retrieval efficiency. 相似文献

《Information processing & management》2001,37(5):661-675
The Web is revolutionizing the entire scholarly communication process and changing the way that researchers exchange information. In this paper, we analyze two views of information production and use in computer-related research based on citation analysis of PDF and Postcript formatted publications on the Web using autonomous citation indexing (ACI), and a parallel citation analysis of the journal literature indexed by the Institute for Scientific Information (ISI) in SCISEARCH. Our goal is to establish a baseline profile of computer science “literature” as it appears in the published journals and as it appears on the publicly available Web. From this starting point, we hope to identify additional research areas dealing with information dissemination and citation practices in computer science and the utility of autonomous citation indexing on the Web as an adjunct to commercial indexing 相似文献

人居科学的超学科性质和特征 《科学学研究》2020,38(4):603-608
通过超学科概念的梳理，认为超学科是以模式3知识生产为基础的知识创新，涵盖了编码知识和默会知识，突破各单一学科固有知识边界和学科本身的藩篱。超学科没有范式，复杂性研究为其共同的学术硬核。在信息化网络社会，超学科注重学科与非学科知识的融合，注重不同层次间的整合，是多层次、多维度的知识集群。人居科学的超学科性质，在于人居本身的复杂性、多维性和多价值观。人居的概念几乎包含了人类社会生活的全部，不同学科的视线均可在“人居”这个研究对象上交叠。人类居住是人类从自然中分异出来，并独立于世的助推器，是人类思维形成、价值观形成的重要基础。人居科学是研究者、设计者、建设者、使用者等共同表述新愿望、共同达成从理论到方法的一致、共同产生新知识的过程。人居科学的超学科特征，是以复杂性研究为内核，以人居地域系统、社会信息网络系统为基础，以众多的知识集群和学科集群为主体，共同构成的开放的学术体系。 相似文献
