Recommender systems can be a powerful tool for digital libraries if they implement the systems right to information seekers. While patrons have shown an increased interest in recommender systems, digital libraries ought to offer personalized services and assist users both novice and experienced with more sophisticate information retrieval technologies. By guiding users to timely, accurate, and suitable resources within the library the recommender system could take the place of the reference librarian of the bricks and mortar library to enhance the digital libraries services.  相似文献

Traditional Information Retrieval (IR) systems have limitations in improving search performance in today’s information environment. The high recall and poor precision of traditional IR systems are only as good as with the accuracy of search query, which is, however, usually difficult for the user to construct. It is also time-consuming for the user to evaluate each search result. The recommendation techniques having been developed since the early 1990s help solve the problems that traditional IR systems have. This paper explains the basic process and major elements of document recommender systems, especially the two recommendation techniques of content-based filtering and collaborative filtering. Also discussed are the evaluation issue and the problems that current document recommender systems are facing, which need to be taken into account in future system designs.

Controlled Digital Lending(CDL) is a new model by which libraries digitize materials in their collection and make them available for controlled lending. CDL was initially introduced 10 years ago and has been developed quickly after 2020. This paper sorts out the concept and development of CDL, and divides the process of CDL into embryonic stage(2011-2017), exploratory stage(2018-2019) and development stage (2020 to present). In the embryonic stage, although there were related research and attempts, the specific concept of CDL had not been formed and the practice was not enough. In the exploratory stage, the concept and core principles of CDL had been defined and received plenty of attention in the American library community. During the development stage, the COVID-19 pandemic has brought opportunities for CDL to globalize, and CDL is supported by the library circle around the world. This paper analyzes the feasibility of CDL according to the relevant laws and regulations in the United States, Europe and the international community. In the United States, CDL is mainly based on the principle of first sale doctrine and fair use; in Europe, CDL is mainly related to relevant directives and copyright restrictions and exceptions; among the international community, CDL basically complies with the relevant provisions of the three-step test. This paper summarizes the status quo and specific operation mode of CDL practice abroad, in the hope of providing suggestions for the specific practice of CDL in Chinese university libraries. The authors sort out the official website documents of well-known foreign library organizations and CDL tool development institutions, summarize foreign practical cases of CDL, and analyze related application cases in foreign university libraries and CDL tool. This paper discusses the legal possibility of implementing CDL in China. A further review of relevant domestic laws has found that, although the Copyright Law of the People’s Republic of China only stipulates 12 acts that can use works without permission and remuneration, the court can still determine that the mode of CDL constitutes fair use based on the general provisions of the fair use in dealing with cases related to CDL. Lastly, this paper points out that China’s libraries, especially university libraries, shall limit the books types, reasonably apply CDL tools, actively cooperate with publisher, and build the platform of digital lending resources sharing to promote the digital services transformation of physical library in CDL way. 38 refs. © 2023, Editorial Office of Journal of Library Science in China.

Recent developments in globalizadon have led to a renewed interest in cultural dimensions. Individualism and collectivism, suggested as the most significant concepts of cultural dimensions, have been theoretically analyzed by many scholars and linked to fields like management, cross-culture commumcation, etc. This paper mainly explores how individualism-collectivism influence personal relation- ships of Chinese and Americans. then analyzes the differences under the influences of cultures. In accordance with the fact analysis, this paper provides valuable reference for cross-cuture learners to better understand how peoples in two countries deal with their relationships, and for those who need to deal with international interaction to enhance cooperanon while reduce the cultural conflicts.  相似文献

Open Access and the Developing World   总被引:2,自引:0,他引:2  
Till about 15 years ago, almost all information exchange among scientists and scholars was mediated by print and even then researchers in the developing countries were at a great disadvantage as their libraries did not have the resources to subscribe in comparison with even a small fraction of journals libraries in advanced countries. But the Internet and the World Wide Web initially exacerbated the gap between the rich and the poor countries, as many poor countries were slow to acquire these technologies and the infrastructure (especially bandwidth). Soon it became clear that thanks to these technologies we now have the unprecedented opportunity of having a level playing field in the matter of accessing scientific and scholarly information. Transforming this opportunity into reality is entirely in the hands of the researchers themselves. Imagine a world where every scientist places his/ her research papers, which (s)he wants to give away so others can read and make use of, in a public archive. Anyone anywhere in the world, of course having an Internet connection, can access, download, and read those papers. This is a win-win situation for all: the reader gets to read what he wants to read at very little cost; the author gains greater visibility for his work and the work reported is likely to have greater impact than if it were to be made available only through a toll-access journal. Although the logic is so simple, in reality such archives were not coming up for a very long time. In spite of the fact that computer scientists and physicists had shown about 15 years ago the great advantages of such archives. Recent studies by Alma Swan and others have shown that a very large proportion of scientists are not aware of open access and therefore what we need is focused advocacy. Even among those who know of OA, many are not depositing their papers in archives but say they would if they are asked by their bosses or their funding agencies. Clearly the ball is in the court of scientists and policy makers. OA is especially advantageous to the developing countries as the current access to literatures is poorest in these countries.  相似文献

To develop small—sized special public libraries in the cities is favourable to enlarging thecoverage of library services.The optimum size of library holdings is 100 thousand,because thatis the time when the availability of the holdings reaches the highest level.Besides,the investmentof establishing a number of small—sized libraries is much less than that of establishing a largerone.  相似文献

The multi-point regional online book circulation platform is a collaborative service model which realizes the integration of regional library warehousing and automatic management of the whole process by cloud platform in a certain area. The concept and algorithmic technology application of the intelligent collaboration provide the technical support for the resource control and allocation, the multi-agent cooperation and interaction, the business and service coordination for the multi-point regional online book circulation platform. The multipoint regional online book circulation platform based on the intelligent collaboration can relieve the pressure of library collection space, expand the radiation range and service radius of collection resources, and facilitate the storage, deployment and service of regional literature resources, all of which meet the requirements of green and energy saving development of smart libraries. It is found that the multi-point regional online book circulation platform based on the intelligent collaboration has the application scenarios and service functions for user service, intelligent stereo book warehousing and library management, and it is a platform service supply mode of smart libraries incorporating management and service. With a variety of technologies such as Internet of Things, big data, machine learning, intelligent collaboration, cloud platform, etc., this model has the following functions: supporting the multi-intelligent device collaboration management, the dynamic multi-task allocation and the multi-agent intelligent collaborative decision-making, which could be helpful for the collection space planning, resource allocation and joint decision-making among libraries; forming the integrated service model, which could optimize the business flow collaboration, prospective literature resource allocation and intelligent recommendation; implementing the remote intelligent coordination control for the data security and risk and emergencies, which could realize the integrated safety management and standardized operation of multiple libraries with a small amount of human, material and financial resources. The primary construction scheme of this platform has been adopted and put into practice by Foshan Library. After nearly one year’s operation, it has achieved good social benefits and recognition. 12 figs. 56 refs. © 2023, Editorial Office of Journal of Library Science in China.

The realization of color conversions in accordance with the ICC technology is the basis of quality management in modern desktop publishing systems. An important point is that the result depends on the specific technological process, therefore the fine adjustment of the control systemis required. For such a multi-step process as flexographic printing is the reprofiling a complicated, labour-intensive and long procedure. The systems based on the ICC profiling, have several restrictions on use in flexographic printing. These restrictions are concerned mainly with the technologies of platemaking and printing processes, as well as with the usability of arbitrary quantity of printing inks, their combinations and with the need for color separation using in the autotype color synthesis of additive inks.    相似文献

The major content of the study of library users is the study of their psychology. Readers emotion is subject to the library s environment, the quality and quantity of the documents and the emotion of the readers themselves as well. In order to make a good job of reader services, the librarians, in addition to their erudition and skill, should have the following three qualities: 1) self-cultivation, 2) ability to observe and analyse the readers psychology, and 3) sedate and refined appearance.  相似文献

The National Digital Information Infrastructure and Preservation Program (NDIIPP) was initiated in December 2000 when the U.S. Congress authorized the Library of Congress to work with a broad range of institutions to develop a national strategy for the preservation of important at-risk born digital content. Guided by a strategy of broad collaborations and iterative learning, the Library of Congress began catalyzing a national network of partners dedicated to collecting and preserving important born-digital information. Over the last six years, the Library and its partners have been engaged in learning through action. Our investments in preservation partnerships, public policy deliberations related to intellectual property challenges, basic technical research, and network architecture models have increased our understanding of the sustaining roles and functions for a national network of diverse stakeholders. The emerging network of networks is complex and inclusive of a variety of stakeholders: content producers, content stewards and service providers from the public and private sectors.  相似文献

The OAIS model has gained widespread acceptance as the fundamental design reference model for an archival system by the digital library community. One of its core entities is Preservation Planning, for which central functional entities are given yet without every detail breaking down into activities requirements. The Planets Preservation Planning approach addresses this by providing a way to make informed and accountable decisions on which preservation strategy to implement in order to most suitably preserve digital objects for a given preservation context. It allows the explicit definition of requirements and goals and offers a systematic way to evaluate preservation strategies. This paper shows the implementation of the Develop Preservation Strategies and Standards function of the OAIS model through the Planets Preservation Planning approach. Moreover, the paper examines the information flows within the OAIS Preservation Planning entity and with other functional entities with respect to the Planets model.  相似文献
