中文期刊文献数字对象唯一标识符的研究 总被引：1，自引：0，他引：1
本文在分析比较国外数字对象唯一标识符前沿研究的基础上,结合中文期刊文献数字对象的实际情况,建立了中文期刊文献数字对象唯一标识符(CSICI)的结构框架,包括期刊标识段、文献内容标识段和控制段三部分.同时,针对中文期刊文献的特点,就题目特征项的抽取方法和汉字的标识方案,设计了10种比较试验方案,并建立了包含26万余条中文期刊文献题录的试验性数据库.通过对比分析各种方法,表明提取题目前10个汉字的拼音首字母方法最优,选定为CSICI的实际编码生成方案. 相似文献

认为国外持久标识符的研究存在研究对象过于具体、应用范围有限等不足,很大程度上是由于没有在一个整体框架指导下来开展研究所致,鉴于此,提出一个持久标识符互操作参考模型,模型主要组成部分是持久标识符域,包括登记机构、内容提供商以及解析器等,对三类数字资源实体（数字对象、作者、机构）和持久标识符之间的关系进行标准化,便于管理、表示和呈现数字资源,并可为实现正确的互操作解决方案和交换奠定基础。最后,指出本模型在安全性、可伸缩性等方面有待进一步完善和改良。 相似文献

数字对象标识符(DOI)是一种用于在数字环境下鉴别和交换知识产权的系统。DOI系统提供一种框架，用以管理知识内容、将用户和内容提供商连接起来、方便电子商务，实现各种媒体形式的自动化的版权管理。该系统由国际数字对象标识符基金会管理和指导。美国、澳大利亚和欧洲的数字对象标识符的注册代理机构已经分配了数以百万记的标识符。 相似文献

Information seeking and its dimensions have been analyzed and measured in different disciplines and contexts and the relationships to other variables, such as gender, task, knowledge, personality, experience, and expertise, have been measured by researchers and have yielded helpful results. In this study, the relationships between information-seeking behavior and prior knowledge of graduate (MA and PhD) students at Tehran University were tested and analyzed. Results show positive and strong relationships between these two variables. Moreover, some dimensions of information-seeking behavior and some aspects of prior knowledge (expertise, familiarity, and past experience) had positive and significant relationships. 相似文献

The creation of an instant messaging (IM) service is described. The challenges encountered in developing, launching, and maintaining the project are examined and include technical support, archiving, balancing different formats, privacy, assessment, training, and the effectiveness of the IM channel. The process of choosing an aggregator and a widget and redesigning the online reference services portal is explored, and best practices that evolved are identified. Useful strategies and concerns that emerged are discussed. Factors contributing to an overall increase in use are outlined and include convenience, simplicity, and reliability. 相似文献

The United States’ National Oceanic and Atmospheric Administration (NOAA) operates over one hundred observing systems and numerical models providing information and forecasts about the planetary environment from the bottom of the ocean to the surface of the Sun. Collected NOAA data constitute an irreplaceable resource that must be well-documented, discoverable, accessible, and preserved for future use. Good data management should therefore be part of NOAA's core business practices, and employees and leadership should be aware of their roles and responsibilities in this arena. NOAA has developed an Environmental Data Management (EDM) Framework document that discusses Principles, Governance, Resources, Standards, Architecture, Assessment, and the Data Lifecycle, and which also enumerates specific recommendations. The NOAA EDM Committee has issued Directives pertaining to data management planning, archiving, data access, metadata, and other topics. A Data Catalog has been established, and a project to assign persistent, citable identifiers to archival data is well underway. Numerous groups at NOAA are performing technical work related to data access, usability, and preservation.The purpose of this article is to describe these documents and activities in order to share our experiences and to provide guidance and encouragement for improved data management practices and processes at other organizations. 相似文献

For public libraries, as with most organizations, effective strategic planning is critical to longevity, facilitating cohesive and coordinated responses to ever present and ever changing political, economic, social, and technological (PEST) forces which shape and influence direction. Strategic planning is widely recognized as a challenging activity, however, which can be both time consuming and unproductive, and there exists limited guidance regarding how to evaluate documented and disseminated strategic plans, particularly within the not-for-profit sector. In response, this research proposes and tests an inspection-based approach to the evaluation of strategic plans, based upon a rubric specifying the key attributes of each of the core components of a plan, combined with an appropriate assessment scale. The rubric provides a method to identify and assess completeness of strategic plan, extending to qualitative assessment of communication aspects such as specification and terminology, and synergistic aspects such as cohesion and integration. In the most comprehensive study of its kind to date, the method is successfully trialed across the devolved Scottish public library sector, with the strategic plans of 28 of the 32 regional networks evaluated. Of the 28 plans, 17, or 61%, were found to be incomplete and/or to contain contradictory or uncoordinated components. It is recommended that Scottish public libraries improve not only completeness of plans, but also their precision, specificity, explicitness, coordination, and consistency, and overall mapping to library services. Recommendations are made for further widespread application of the rubric. 相似文献

University museums and their collections are among the oldest and most significant in the world, yet their role and future is being questioned. They have critical needs for facilities, staff, and support. At risk are millions of objects that document our natural and cultural history and programs for research, teaching, and public education and exhibits. The museums are attempting to redefine, reposition, and clarify their educational mission. Museums such as the Sam Noble Oklahoma Museum of Natural history are successfully meeting the challenges through strategic planning and funding for new facilities. Other museums are finding solutions with partnerships, links, and tailor‐made service programs. New leadership and management will need to emerge for university museums to reestablish their stature and relevance. Physical and intellectual access to the museums and their objects is a key to their future. The new technologies are tools that museums can use to improve their interpretive programs and increase the depth of their research. Facing shared concerns and challenges, the museums are generating a growning sense of collective urgency and a call for intenational organization, advocacy, and cooperation, resulting in formation of the International Committee for University Museums and Collections. 相似文献
