信息发现与数字资源重组探讨 总被引：4，自引：0，他引：4
个性化服务将成为数字化信息服务的主流，如何有效提供个性化服务，主要取决信息发现和资源重组的情况。所谓信息发现是以帮助用户大量信息集合中找到与给定查询请求相关的、恰当数目的信息子集；所谓资源重组是数字资源按相同的学科或专业重新编排，形成镜像数据资源库。信息发现和资源重组是网络发展和数字资源多样性发展的客观要求。本文探讨了信息发现机制和资源重组的模式，它们两者是相辅相成的。 相似文献

Anthropologists at seven universities were surveyed in order to discover: the ways in which they go about locating information of value to them; the information sources that they use and that are of the greatest significance to them; the adequacy of the library service being currently provided to anthropologists; and any opinions they have on the subject of their information needs. Results show that anthropologists; information requirements differ somewhat from those of other social scientists. Reference lists in journals and books are often used to locate information sources; journals are the most important information source. However, cultural anthropologists report that their own field data is their most significant source. Anthropologists use pictorial sources and maps more frequently than social scientists in general do; they also make great use of interlibrary loan. Most of the information needs of the majority of respondents are met by their university's library. Older scholars tend to use databases less than younger ones do; online abstracts and indexes are most important to anthropologists than their print versions are. Some respondents express a great desire for a database which would include current references, abstracts, and articles in anthropology. 相似文献

Information service professionals face two fundamental challenges that, taken together, point a direction for service development. The first of these is information overload caused by the proliferation of available data and publications and ever-morecomorehensive and wides~reada utomated means of access to them. The 'second is the fact thai most information seeking transpires with little help from librarians, who have ccnsistently failed to establish themselves as primary information professionals. The following discussion, limited in its implications to public and academic libraries, considers the relationship of these challenges to one another and describes a vision of the future mission of information services, made concrete through specific recommendations. Central to this vision are ideas set forth in two recent books: Value-Added Processes in Information Systems, by Robert S. Taylor, and New Priorities for the Universiv: Meeting Society's Needs for Applied Knowledge and Competent Individuals, by Ernest A. Lynton and Sandra E. Elrnan. 相似文献

In recent years a number of organizations have appeared which offer a variety of information services for a fee. The bulk of their clientele is industry and government. A few former librarians have gone into business because of the restrictible nature of the libraries in which they worked. Many information brokers have library backgrounds, but complain that their library school training did not prepare them to deal with the business world. Brokers are criticized for charging for free information, but they contend that their charges are for the service involved in providing the information. Librarianship is approaching a place that other professions reached long ago: the place where self-employment is normal and valuable. 相似文献
