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

Use of a retrieval algorithm of keypoints in an information system ensuring the frame stability during digitization of archival film footage 
下载免费PDF全文
下载免费PDF全文 One of the main technical tasks of any cinema archives-in which are deposited the movies as film footage-is the digitization of analog content to achieve two main goals, i.e. to provide a termless storage and a secure access to archival film footage Belousov, Vinokur and Vasin. The information contents stored as film footage are very large, many of the films are unique and don't occur in another form; and this storage method makes difficult their access and threatens their existence in unmodified state itself. The film degradation in form of medium shrinkage with aftermodification of geometry in the form of edges' shrinking, bending and bowing of the film surface, and destruction of the emulsion layer degrades the technical quality of the image, and leads to its complete loss. The data presentation in digital form eliminates this disadvantage and increases the accessibility of the film footage, allowing the selective access, including multimedia network, be it TV or Internet.

The Reading History of China, edited by Professor Wang Yuguang , was published by Anhui Educational Press at the end of 2017. This book is the first book on general history of reading in China and fills in the blank of the research field of reading history. The scientific research team headed by Professor Wang Yuguang has been working for many years to establish and improve the theoretical system of the study of Chinese reading history. Through translating and introducing the research achievements of foreign reading history compiling the compilation of reading historical materials and launching case studies they attempted to establish the theoretical system of Chinese reading history. This book is divided into ten volumes. The first volume is “Theory Volume". It discusses many theoretical issues in the study of reading history , including the research progress of reading history at home and abroad the research contents of Chinese reading history and reading culture the national era and regional characteristics of reading history and reading culture; the interaction between reading activities and text changes , social environment and education , social consciousness and religion , academic changes and other factors. China's long-standing reading culture and traditions were refined and summarized. Volume 10 is “the Record of Pictures", which compiles representative pictures related to reading activities in successive dynasties. Volumes 2 to 9 are divided into eleven relatively independent historical stages according to the development of reading history and the main characteristics of each period. On the basis of fully absorbing the theoretical research achievements of reading history at home and abroad and comprehensively grasping the research materials of reading history in China , the book puts forward the core view that reading is a universal social and cultural phenomenon. It holds that reading is not only an individual behavior , but also an important part of human civilized life. Therefore , the reader's reading behavior is inevitably affected by both internal and external factors and the study of reading history should be placed in the overall environment of social history. According to this idea , the book decomposes the internal and external factors affecting reading behavior one by one establishes a research system of Chinese reading history from the perspective of social culture and summarizes the research contents of Chinese reading history into three aspects and eight main topics 1 Discipline foundation and theoretical research , aiming at the construction of theoretical system and basic information; 2) External factors affecting reading , including the relationship between reading activities and text changes social environment and education social consciousness and religion academic and knowledge system , publishing and dissemination of environmental factors; 3) Internal factors affecting reading. It includes reader,s reading behavior , reading environment , reading content, reading concept , reading thought and theory and social reading tradition etc. which shape and influence the reading behavior. The writing of each sub-volume revolves around the above-mentioned framework , focusing on reflecting the characteristics of the times regions and nationalities in each stage of the history of reading. On this basis , the tradition and spirit of ancient Chinese reading are condensed into five aspects. Finally , combined with the compiling experience of The Reading History of China, some topics are put forward for further study such as the collection and publication of reading historical materials the methodology of reading history the contemporary value of research on reading history and reading culture the reading history of a region or ethnic group the study of reading population and the case study of representative readers. 12 refs. © 2019, Editorial Office of Journal of Library Science in China.

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.

The Multi-point Regional Online Book Circulation Platform Based on the Intelligent Collaboration北大核心
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. All rights reserved. 相似文献

A subject analysis of 5195 publications in library and information science (LIS) research in Pakistan over a period of 62 years revealed that the majority of Pakistani LIS research focused on a few subject areas. Pakistani LIS researchers gave little attention to many subjects and completely ignored others. More than a quarter (26.72%) of the total items focused on “information treatment for information services” while 22% were related to “libraries as physical collections.” Other areas with some attention included “industry, profession and education” (12.32%) and “theoretical and general aspects of libraries and information” (11.40%). Researchers paid little attention to “housing technologies,” “technical services in libraries, archives and museums,” and “management.” 相似文献

Information Retrieval systems typically sort the result with respect to document retrieval status values (RSV). According to the Probability Ranking Principle, this ranking ensures optimum retrieval quality if the RSVs are monotonously increasing with the probabilities of relevance (as e.g. for probabilistic IR models). However, advanced applications like filtering or distributed retrieval require estimates of the actual probability of relevance. The relationship between the RSV of a document and its probability of relevance can be described by a normalisation function which maps the retrieval status value onto the probability of relevance (mapping functions). In this paper, we explore the use of linear and logistic mapping functions for different retrieval methods. In a series of upper-bound experiments, we compare the approximation quality of the different mapping functions. We also investigate the effect on the resulting retrieval quality in distributed retrieval (only merging, without resource selection). These experiments show that good estimates of the actual probability of relevance can be achieved, and that the logistic model outperforms the linear one. Retrieval quality for distributed retrieval is only slightly improved by using the logistic function. 相似文献

Questions of collection bias in library journal collections usually turn on a left-right political contrast. This article presents another approach that distinguishes between corporate and non-corporate controlled publications. Using this method, the catalog holdings of all Canadian academic libraries were searched to determine the penetration of socio-political titles of mainstream “corporate publishers” and those of “small publishers.” Canadian academic libraries privilege, by a wide margin, mainstream titles published by corporate entities, although some libraries have impressive “small publisher” collections. This article also analyzed the availability of mainstream and small publisher journals provided by ten popular electronic vendors. These vendors provide very low access to non-corporate “small publisher” titles while covering 100% of surveyed mainstream titles. The implications of such provision rates are examined from the perspective of the scholarly browsing process and the role of the university. 相似文献
