我国最新修订的叙词表编制标准,新增了叙词表与其他词表的互操作内容,主要从映射模型、映射类型、映射技术、映射数据管理与维护等方面指出了叙词表互操作的通用原则和方法,并具体分析了叙词表与其他各种受控词表之间建立映射及维护的问题.互操作标准的提出,不仅可以指导和规范我国叙词表和其他受控词表之间的互操作实践,而且为受控词表的跨系统互操作研究提供了强有力的支持,具有十分重要的意义. 相似文献

通过对ISO2788-1986、GB13190-1991以及ANSI/NISO Z39.19-2005三部词表编制标准中宏观结构部分内容的比较分析研究,可知叙词表的宏观结构显示方式在不断完善.概念图、本体显示、详情显示等一些新的词表可视化显示开始投入使用,而以叙词表为依托发展起来的OverView、Kenardus项目也在积极研发之中.叙词表已不仅仅是标引查词的工具,它已逐渐成为网络信息资源的一部分,并运用到构建知识组织系统中. 相似文献

网络信息时代叙词表的编制与应用 总被引：3，自引：1，他引：2
统计我国叙词表的编制情况,分析在网络时代叙词表的发展趋势以及编制和应用特点。认为在叙词表编制方面,将会实现利用海量的数字信息资源,通过计算机抽取相关的专业术语和词间关系,在领域专家人工辅助干预下,建立适合现代网络信息资源特点和大众化的领域用户使用的叙词表。叙词表主要用于计算机系统后台的标引和检索,用户主要为使用网络检索专业信息的普通用户,数字界面和可视化将是叙词表的主要表现形式。 相似文献

网络环境中汉语叙词表的自动构建研究 总被引：2，自引：0，他引：2
为解决网络信息检索效率低的问题,需要把叙词表等控制机制引入到网络检索系统中,但传统词表编制方式已经不能满足网络信息检索的需要.本文制定了一种汉语叙词表自动构建方案,以财税领域为例,采用模式识别、词聚类、同现分析等自然语言处理技术实现自动识别词间等同关系、等级关系和相关关系,从而构建一部财税领域叙词表,最后对所构建的叙词表进行测评.相比传统叙词表编制方法,自动构建叙词表能降低编表专家的智力负担,而且编表时间短,费用低,时效性强,符合普通用户的检索习惯.但对词间关系的识别不如人工编表时精当可靠,所以需要人工辅助判定. 相似文献

Many health sciences libraries are now considering integrated automated systems for an investment of several hundred thousand dollars. The request for proposals (RFPs) is the usual method of selecting candidate vendors for close inspection of promising systems. This paper draws upon the experience of the Library of Rush University and that of twelve other health sciences libraries. The libraries were interviewed by telephone using a short questionnaire that asked them to compare the RFPs with the systems actually obtained and their experiences in implementing them. The libraries were also asked, with the benefit of hindsight, what would they have done differently. Four vendors were also interviewed by telephone, in order to get their point of view. 相似文献

AbstractThis study surveyed Government school libraries in Benue State before the creation of Kogi State from Benue. The study was carried out using 100 non-pretested questionnaire forms of which only 70 were returned with sufficient information for analysis and generalization.The study focused on how over 60 government school libraries, scattered over a large geographical area with a poor road network and few funds, are centrally administered. Further, the study covered the extent of co-operation between school libraries and their relationship to the central administration at the Ministry of Education and other library authorities elsewhere. The acquisition policy, staffing, processing, distribution and inspection, as well as operational standards are discussed and suggestions for improvement are supplied. Possible areas for further research relating to the study are raised in conclusion. 相似文献

Rapidly developing technology has changed the environment in libraries so that some degree of computer search ability is required now in order to give standard, non-obsolete reference service. New library school graduates regularly receive a basic understanding of DIALOG, BRS and other database utilities, but some feel more inclined toward working with computers than others. At the same time, seasoned librarians are faced with new learning requirements for computer searching. How do librarians in the "transition generation" handle the change required by professional technological development? A wide range of responses - from enthusiastic to reluctant - requires flexibility and variety in training and continuing education methods. This paper will address the human factor in some issues of broad technological change. The authors will offer some observations about how we as a profession are adapting to the new environment of computer-enhanced information. A case study of one library's experience with training and continuing education for online searching will illustrate a response to this changing library environment. 相似文献

The challenge of teaching first-year students basic library skills is to make the process interesting and relevant. In this collaborative project between professor and librarian, metaphors in everyday life were used as a springboard for library research. Through the metaphor project, Honors students learned how to approach a topic, break down its parts, brainstorm searchable words, and make assumptions about ways to research. Most importantly, they learned to evaluate the results of their research to ensure that, in the materials located, they had actually found a real life application of their metaphor. 相似文献

In spite of planned development in the independent India, gaps remain in its basic infrastructure, adding to the variety of structural disadvantages and disparities. Studies on information systems serving rural communities have focused on a few sectors like agriculture, health or education. The paper touches upon the role of traditional media, developments in information and communication technologies (ICTs), the digital divide, and computerization at the rural level in various parts of the country. An experiment conducted by the National Institute of Rural Development, Hyderabad, on the use of IT to deliver information through the establishment of Public Information Kiosks (PIKs) is described in detail. Issues that were considered for humanizing the establishment of PIKs were identified. It is concluded that organizational linkages and networking capacities are to be strengthened for ‘digital unity’ to provide multiple opportunities to the rural communities to exploit local resources for their self-development. 相似文献

老年人信息素养教育的理论导向决定了其价值定位与发展方向.对老年人信息素养教育的相关理论导向进行分析,进而指出其存在的不足:以康乐理论、社会适应理论为主导的理论导向忽视了老年人的社会主体地位,权利理论、福利理论、终身教育与终身学习理论等理论导向又面临着现实基础薄弱的窘境,因而确定以促进老年人社会参与为导向的理论选择才是我国老年人信息素养教育的可持续发展之计.参考文献28. 相似文献
