As new venues of information and tools for information access are emerging, people's online information seeking behavior is dramatically evolving. While a majority of well-established and classical models of information seeking and behavior are still valid, there is a growing need to study and explain novel information sources and information seeking behaviors that are unique to these sources. One emerging domain is social question and answer (Q&A). This article develops a research agenda for social Q&A, reviewing recent studies and identifying core issues, questions, and challenges. 相似文献

网络信息资源著作权集体管理制度研究 总被引：11，自引：0，他引：11
在网络信息资源的开发利用过程中,如何解决网络传播中海量信息资源的著作权问题,已 经成为世界性的难题。但信息技术的不断发展,使用作品的方式和途径越来越多,著作权人对作品 的控制也越来越有限,而要求使用者逐一取得使用许可并支付费用基本上也不现实。因此网络环 境下我们有必要在坚持著作权保护基本原则的前提下,通过著作权的集体管理来加强对网络信息 资源的保护。建立和完善网络信息资源著作权集体管理制度应确定网络信息资源著作权集体管理 机构的组织形式,明确其法律性质和职责范围,并弄清网络信息资源著作权集体管理组织获得著作 权人授权的方式和将使用权授予使用者的方式。 相似文献

Dentists, as health professionals, need access to information. As in other health sciences, the increase in the rate and volume of published information has made it more difficult for them to keep up with new developments. Five hundred randomly selected dentists in Louisiana were surveyed to determine what information dentists seek and what sources they prefer. Responses indicated that dentists need information on new techniques in dentistry and that preferred sources are professional colleagues and personal journal collections. Libraries were found to be used only infrequently as sources for information. Implications for planning libraries for applications- and technique-oriented professions are discussed. 相似文献

Copyright law is one of the many policy forces shaping the utilization of information resources. American copyright law has undergone many changes with profound consequences, particularly for educational and scholarly uses of existing copyrighted works. This article summarizes recent developments in the law, with a focus on their consequences for users at American colleges, universities, and libraries. The purpose of this study is to highlight the principal implications of an evolving copyright law and especially to assist librarians, administrators, and other policy makers. They must address these issues and devise standards of practice that avoid legal challenges but that also optimize the use of available resources. The article concludes with guidance for future concerns and planning. 相似文献

A complex and dynamic economy requires the most timely and comprehensive information. The expansion of the Internet is perfectly suited to the requirements of the economic researcher. Two specific sources of Internet accessible economic information, the Economic Bulletin Board and EconData are described and contrasted. Directions for access are provided and a brief listinrg of other resources for economic information are listed. Illustrations of the various screen access points are also included. 相似文献

The concept of a ‘publication’ no longer applies only to printed works; information technology has extended its application to several other types of works. This article describes a facility called the Common Knowledge Library that publishes modules of formally structured information representing facts and knowledge of various kinds. Publications of this new type have some characteristics in common with databases, and others in common with software modules; however, they also share some important characteristics with traditional publications. A framework for citation of previous work is important in order to provide an incentive for contributors of such modules. Peer review – the traditional method of quality assurance for scientific articles – must also be applied, although in a modified form, for fact and knowledge modules. The construction of the Common Knowledge Library is a cumulative process; new contributions are obtained by interpreting the contents of existing knowledge sources on the Internet, and the existing contents of the Library are an important resource for that interpretation process. 相似文献

The lack of attention given to federal court rules in legal curricula and lack of uniformity in bibliography coverage creates a problem for researchers in locating and using rules; the reference librarian must overcome this problem. This article is a guide to federal court rules, providing the location of these sets in standard legal bibliographic sources and information regarding commentaries and other interpretive works. 相似文献

图书馆作为构建和谐社会的文化阵地,是一种组织性极强的社会系统,并具有一定的整体性和稳定性。它一方面对人类文明和知识财富进行守望;另一方面根据环境的变化和发展进行信息的组织、管理、咨询和服务。调查发现,多数图书馆只开展传统的服务,但为经济提供深层次增值业务的信息服务较少。笔者就图书馆信息服务功能进行研究,阐述其概念、内涵和特征,通过构建图书馆信息服务机制,增强主动、竞争服务意识,加强信息资源的开发、消费与保护,提高信息服务水平和质量,促进教育生产力水平的提升,实现经济效益最优选择。 相似文献

Sierra Leone's knowledge economy stresses the importance of information for national development, and libraries have a crucial role to play in this development. Libraries are catalysts for human progress because they help in the development and transmission of knowledge and culture; they foster civic awareness in support of economic productivity and innovation in society. Although many economic programs have been implemented by the Sierra Leone government, a vast amount of information is unused, either because national decision-makers do not realize its importance or because people who might want it do not know how to access it. The public library has to play an increasingly significant role if rapid economic recovery is to be made. This article examines Sierra Leone's economy in postwar reconstruction, the importance of information and knowledge in a knowledge economy, and the problems affecting library services and how the public library can overcome these problems and make meaningful contributions to the knowledge economy. 相似文献

Integration of multiple information systems of a medical center will change the way physicians work and practice medicine in the future. Several major steps must be taken by an institution to make this a reality. Since 1983, Georgetown has been engaged in an Integrated Academic Information Management System (IAIMS) project to bring together multiple sources of information that reside on different computers and database systems. Georgetown is developing a Biotechnology and Biomedical Knowledge Network that includes informational and clinical databases, scholar workstations, instruction on computer use, a campuswide network with local area network nodes, and a modular approach to systems integration. The IAIMS project, spearheaded by the medical library, has enabled a broad spectrum of health professionals to benefit directly from new, dynamic information services. The network is heavily used; in 1991, more than 2,100 individual users conducted more than 148,500 computer functions and more than 104,000 searches. There is economy of scale in high-volume use. Overall, the average search cost is $1.57; for high use databases the cost is $0.38, and for low use, it is $9.41. As described in this paper, IAIMS offers a cost-effective means of enhancing patient care by improving information services to physicians. At Georgetown, IAIMS has advanced the concept of integration, accelerated use of computers in education, increased user acceptance of advanced technologies, and established cost factors for providing information resources. While progress made in improving the transfer of medical information is impressive, it is clear that IAIMS requires several more years of support to achieve full implementation. 相似文献

Evolution of information production processes (IPPs) can be described by a general transformation function for the sources and for the items. It generalises the Fellman–Jakobsson transformation which only works on the items.In this paper the dual informetric theory of this double transformation, defined by the rank-frequency function, is described by, e.g. determining the new size-frequency function. The special case of power law transformations is studied thereby showing that a Lotkaian system is transformed into another Lotkaian system, described by a new Lotka exponent. We prove that the new exponent is smaller (larger) than the original one if and only if the change in the sources is smaller (larger) than that of the items.Applications to the study of the evolution of networks are given, including cases of deletion of nodes and/or links but also applications to other fields are given. 相似文献
