Borrowing From e-commerce; Are Recommender Systems Good for Libraries? For past 10 years recommender systems have attempted to match customers to materials in the e-commerce world. Utilizing specifically designed recommender systems to meet the needs of patrons, collaborative filtering, and content-based recommender systems are the two basic types with several hybrids created from these two have been significantly enhancing digital library services. Security issues come into play in a special way with libraries, and plagiarism can also affect recommender quality. Open Source tools may be the answer for libraries and their customers, enabling a better utilization of all that a library has to offer. 相似文献

Since the electronic resources and Internet Web sites became popular, distance education courses offered via the Internet could play an important role in providing global digital resources and teaching the knowledge of international library and information standards for bibliographic databases with electronic and web resources.This paper uses the example of the author's new online course: ILS 608 Cataloging and Development of a Digital Union Catalog for Ancient Chinese Books to demonstrate the global resources sharing of the different information organization knowledge and standards practiced by library and information professionals in the East and West world from library and information communities.From this online course, students will be able to access digital resources downloaded or linked to the course units, and to learn the knowledge for cataloging ancient Chinese books from both East and West world. Most of these digital resources are provided online by academic and research institutions and nat 相似文献

文献推荐系统：提高信息检索效率之途 总被引：2，自引：0，他引：2
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.

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

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.

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

Today, access to digital information is essential to patrons using public libraries, whether they have contact with computers at home, work or school or whether the public library is their only contact. In order to evaluate and ultimately enhance public library digital resources and services, it is critical for administrators, librarians and digital information architects to recognize the impact their current digital offerings have on users. This study utilizes a survey to gauge the perceptions of patrons who use digital resources and services in six urban New England public libraries as part of ongoing research into digital information access in public libraries in the United States from the perspective of users. 相似文献

Information users face increasing amounts of digital content, some of which is held in digital library collections. Academic librarians have the dual challenge of organizing online library content and instructing users in how to find, evaluate, and use digital information. Information architecture supports evolving library services by bringing best practice principles to digital collection development. Information architects organize content with a user-centered, customer oriented approach that benefits library users in resource discovery. The Publication of Archival, Library & Museum Materials (PALMM), a cooperative digital initiative of the state university libraries of Florida, demonstrates the value of information architecture to digital libraries. 相似文献

Based on the investigation of the position of user service for constructing digital libraries in the big data era, this paper points out that not only data resources of modern digital library have the characteristics of big data, but also the existing library services need to use big data methods to achieve reform and innovation, including resource transferring, resource utilization, social identity, thinking innovation. We focus on the importance of user services and types of big data resources that digital libraries can utilize, which include big data within libraries such as user behavior data and digital literature resource, and other big data outside libraries such as scholarly big data. We also examine the problems and potential of digital libraries in the age of big data relative to data, technology, services, and users. Using existing big data resources and considering the characteristics of current users' needs from the perspective of users, more effective ideas and methods to improve existing services in digital library can be put forward. At the same time, it is the personalized need of users in the age of big data that constitute the driving factor for the development of digital library from resource-sharing service to user-oriented service. 相似文献
