from http://smyz.fj.cninfo.net/offices/tsg/dl/ArticleShow.asp?ArticleID=105 On the Virtual Library of personalized service: Chen Jin posted from: http: //www.fjinfo.gov .cn / publicat / qbts / 031 / 3. Virtul Library is the information resource system that has gradually developed with the library's electronic, digital, and networked, it has broken through the traditional "collection" ", Fundamentally realize the digitization of literature resources, networked information and its sharing. As the tool available on the Internet, the virtual library collected a large number of zero-scattered network information in accordance with different disciplines, and stored in web providers and browsing through ordered combinations. Therefore, its design principle is achieved by information collection and information organization of library management personnel. As an open hardware collection platform, modern virtual libraries are not only integrated with advanced network communication technology, but also have a good user interface. Therefore, how to achieve personalized customization services for the construction of the current virtual library in terms of various types of users. 1 Establishing the concept of personalized information services With the process of social information, personalized production and services are gradually recognized by society. The Personalized Customization service is an inevitable requirement for the development of modern libraries. Traditional libraries have always been to collect the translation of the Tibet literature, waiting for the readers to go to the door, and the developed digital library and virtual library are not only in modern technology, but also emphasize that the service method must be passed by passive to active, establish the concept of user-supreme In accordance with the user's requirements, the potential user group is stimulated. For example, in college research institutions, with the diversification of research, readers' information needs are also gradually tending to personality, specialization, dynamics providing relevant disciplines latest network resources, which not only makes users understand academic information related to professional fields, but can make users feel Go to the humanistic care of the modern library. At present, online information resource organizations are diverse, such as hypertext links, home menu access, database retrieval, etc., and additional Internet also has a lot of famous search engines in its development, such as Yahoo, Google, etc. Automatic classification, integrated function, so that they become a high-quality retrieval tool on the network, but these search engines still have many things that are not satisfactory, such as the disorder of information, not enough qualifications Waiting for the problem, and the developed virtual library is well solved these problems. It is aimed at research institutions, laboratories, academic forums, experts and scholars who have related research institutions, laboratory, academic forums, experts, etc. URLS is systematically organized, stored on a web, for users to browse and retrieve, it always advocates interactivity communication with users. As a modern virtual library, a variety of intelligent technologies should be fully utilized. Personalization services are carried out for user characteristics, so users do not need to spend too much energy in massive network information, as long as they open personal accounts on virtual libraries, enter personal information And demand, you can get the processed information and information products in time. Therefore, it is necessary to meet the needs of different levels of personalized intelligence, it should be an important part of the current virtual library user service. 2 About the Virtual Library Personalized Services 2.1 Network-based personalized custom service Virtual libraries Mode generally consists of user interface, network, information resources, database management and retrieval systems, and additional retrieval systems, relying on various digitization Special gallery, CD database and online database system, rich Internet literature resources. In terms of public information retrieval services: Provide unified cross-library retrieval services including public online catalog, CD database retrieval, self-built database retrieval, online resource library search, and online full-text database retrieval.
The personalized customization of the virtual library is diverse, such as it can customize relevant professional columns and news, customize electronic resources, custom audiovisual services for a user's needs, custom electronic resources, custom audiovisual services. It also provides personalized information services based on user privileges, user interface, information resources, etc., achieving different privileges, different user-style interface, can access different information resources; carry out interactive information services : Provide an online literature appointment, online reference information, online literature transmission, online literature procurement application, online internet internet interactive information services: Provide active information push service: including online journals, online special service, online Resource subscription service and check information service, and directively push to the user desktop through the mail system; additional auxiliary user services: including library news / announcement, user opinion box, BBS, FAQ, online user education Wait. Specific implementation, the virtual library can refer to the model of e-commerce, such as the different users, release different privileges, user authentication, and implement online payment electronic settlement on the charging project, and in the acquisition organization of network information, It is necessary to collect network information in accordance with the Ordinance of the National Intellectual Property and Copyright, and the privacy of the user's privacy of the user will be reasonably protected. A true virtual library not only has rich digital resources, but also reflects the "people-oriented" service concept. Determine the service direction according to its own important user group, create a friendly user interface, and use the household customization service. Have your own MYLIBRARY system. Therefore, regularly investigate the direction of the user's topics, seize the law, track the needs of the main user groups, and set the service countermeasures in time, develop information resources, and transform the technical system of the virtual library, thus better serving the user. 2.2 At present, personalized service cases and technological analysis of personalized custom service technologies have been short-lived in foreign libraries, but they have been generally concerned about users. At present, there is a personalized customized service system such as Mylibrary, Mygataway, where Mylibrary is a pioneering in the University of Connell University. MYLIBRARY was put into use in 1999, which consists of two parts: MYLINKS and Myupdates. MyLinks is a tool for users to collect and organize digital resources for users; Myupdates is a tool for notifying the user in a timely manner of the library. The system uses Java dynamic technology to create an HTML page, using Oracle database technology to store user information, using the Kerberos authentication mechanism to perform user authentication tasks. MyLinks allows users to collect and organize the digital resources of the network, and provide two default folders in the MyLibrary system. Users can organize their own information resources to different folders, arbitrarily modify, delete, rename, etc. operating. However, there are many online information resources that the merchant is not able to pay attention to the user. At this time, you need to use the Myupdates tool. Users can make a command to the MyUpdates system, and the system will retrieve online information in time after the system is certified. Resources and databases, and inform the user in time, regular updates, and users can organize the results into their MyLinks in time. There are also a lot of websites to provide personalized services to users, although not very perfect, to a certain extent, improve the search efficiency and network information utilization.
For example, Shenyang Dongping Software Co., Ltd. has introduced Neusoft Web, integral information sharing and information exchange, providing a comprehensive solution for corporate website construction, providing a wealth of special features for different industries Provide a platform for knowledge management, with information as the core, provide a network of network information organizations, sharing, communication platforms, enhance the capacity of enterprises to manage digital wealth, let information become knowledge - enterprise real digital wealth; support personalization Website administrators can customize the style, layout, etc. of the website, and enterprise users can flexibly customize their personal work space and enhance the company's operating level. Dongping Internet / Intranet application platform not only allows companies to quickly own their own websites, but more importantly, with information as the core, provide a network of network information organizations, sharing, communication platforms, and a platform for knowledge management, users pass Simple operations can be shared on the network, so that information is knowledge-real digital wealth, and easily realize the knowledge management of the company. Another example: IBM's website, by using personalized support, you can add any interested IBM products to your personalized page, and you can selectively subscribe to the content update email notifications for these products, in addition, if you add it Not only a custom product, you can make you first display your most concerned product support content through "customized preferred products". When you visit the site in the future, you will automatically go to your personalized support homepage after logging in, and you can directly browse the related articles of your product. The technology that currently supports personalized information services mainly includes data push technology, dynamic HTML generation technology, database VDB technology, intelligent agency technology, etc., where the promotion technology is information publishing technology, which is the information of the library to collect and processing from the network information source. It is a technical standard and technical agreement to be published to the user through a fixed channel page. The intelligent use of this service uses a complex decision and reasoning feedback mechanism to help users determine information. It allows users to access fixed sites again to get the latest information, it also makes up for the shortcomings in search engines and retrieval tools, intelligence Understand the user's information needs, improve user search efficiency and detection rate, thereby realizing personalized information services in real sense. 3 Problems in 3 Personalized Services and Outlook Virtual Library are high-tech products in the netization of tech, which involve considerable fields, such as: Internet technology, information storage and communication, intellectual property, etc. It is still in a prototype and therefore faces many problems. 3.1 Personalization Technology Says that the MYLIBRARY system is not long in foreign library, and it is not mature in technology and service. Therefore, it is timelyly to track the latest software functions of foreign libraries, and develop personalized service system software suitable for my country. It is the key to virtual libraries to improve user services. 3.2 Intellectual Property Rights and Personal Privacy Problems Since the virtual library source information is mostly downloaded, it will inevitably involve some copyright issues, so it is necessary to control the advanced software technology in accordance with the state's relevant intellectual property rights. Coordinate the relationship between the virtual library and the publisher and the author. In addition, in order to better carry out personalized services, you often need to register some real personal information, which will inevitably involve personal privacy issues. Virtual libraries should establish a good reputation in the user, encourage users to provide detailed personal information, protected by related technologies to further meet the information needs of users.
