下一代Z39.50技术探讨   总被引:16,自引:0,他引:16  
经过20年的经验积累,Z39.50业已成为一个成熟的信息检索标准和协议,但其应用领域仍仅限于图书馆界。Z39.50推广的主要障碍是标准的复杂性和生僻的底层协议。于是ZIG的一些成员发起了一组改造Z39.50的计划——ZING,目的是保留Z39.50有用特征,摒弃过时的和没用的部分, 从而降低实施难度,以形成一个更具吸引力的信息检索协议。其中的SRW方案是以Web服务方式重新定义Z39.50,并做了较大的简化。本文全面地介绍SRW技术规范,并讨论SRW和经典Z39.50的异同。  相似文献

馆藏期刊信息资源的配置   总被引:2,自引:0,他引:2  
目前我国图书馆馆藏期刊资源建设中不同程度地存在着或偏重纸型期刊,或偏重电子期刊,或过分强调现实馆藏或过分依赖虚拟馆藏的倾向。要改变这一局面,应妥善处理好期刊资源配置中以下关系:纸型期刊与电子期刊的关系;中文期刊与外文期刊的关系;专业期刊与非专业期刊的关系;图书与期刊的关系;杂志与报纸的关系;正式刊物与内部刊物的关系;特色馆藏与一般馆藏的关系;现实需要与未来发展的关系;现实馆藏与虚拟馆藏的关系。  相似文献

This essay compares archival accumulation in clerical and secular principalities in seventeenth-century northwestern Germany. As this is known to be the age of confessionalization, the focus is on confessional convergences and divergences in the development of confession, rule, states, and archives. The sources show the emergence of administration, the accumulation of legitimation and evidence via archives, and confessional competition, as well as coincidences of centralization and separation. Catholic and clerical archives were oriented toward persisting written records and historical traditions, while in Protestant and secular contexts, we find novel developments: a new age, new confessions, the need for a new history together with the creation of a new (historical) identity, and thus, new archives. Later success stories that characterized the Protestant secular state as orderly, administration- and rule-related, and possessing well-indexed archives, however, neglect most Catholic and nongovernmental archives and their qualities.  相似文献

The Internet of things (IoT) is the network of objects/things that contain electronics, software, sensors, and actuators, which allows these things to connect, interact, and exchange data. The users, sensors, and networks generate huge amounts of data from which governments can develop applications and gain knowledge using Artificial Intelligence (AI) techniques. Thus, IoT and AI can enable the development of valuable services for citizens, businesses, and public agencies, in multiple domains, such as transportation, energy, healthcare, education, and public safety. This guest editorial for the special issue on IoT and AI for Smart Government, identifies the challenges involved in implementing and adopting these technologies in the public sector, and proposes a comprehensive research framework, which includes both IoT and AI elements for smart government transformation. Subsequently, the editorial provides a brief introduction of the six papers in this special issue. Finally, an agenda for future research on IoT and AI for smart government is presented, based on the proposed framework and gaps in existing literature, supported by the papers that were submitted to this special issue. The agenda comprises four directions i.e., conducting domain-specific studies, going beyond adoption studies to examine implementation and evaluation of these technologies, focusing on specific challenges and thus quick wins, and expanding the existing set of research methods and theoretical foundations used.  相似文献

无论在内容开发、录音制作,还是在产品发行、营销上,车载有声读物都还处于起步阶段。在内容储备与质量、定价与销售渠道、市场竞争力与受众定位等方面存在许多问题与不足,如文本来源单一,内容储备不足;价格过高,销售渠道单一;用户黏性不足,难以养成使用习惯;市场占有率低,难以同其他媒体抗衡,法制建设不健全,盗版侵权问题挤占盈利空间。从车载有声读物自身优势、巨大的潜在市场、丰富的文化资源储备、已有的发展基础四个方面来看,车载有声读物发展具有可行性。从内容与受众、质量与价格、销售与营销、宣传与品牌以及广告与盈利五个角度来看,车载有声读物的发展路径还可以更明晰。  相似文献

The reading of literature fulfils a vital role in any educated and civilised nation. The book is being transformed, as digitisation becomes an increasing reality, however, literature will continue to retain a key place as a critical social and cultural artefact. Story, in whatever form, will continue to provide experiences of joy, amusement, fear, hope, betrayal, curiosity, love, forgiveness and sadness. Literature can do so much more than simply moving and entertaining us. It can impart knowledge, stimulate the imagination and can teach us about language, our world and our relationship to it. It can help us to relate to and understand one another, and can act both as a mortar to build rich personal and textual histories, and a bridge between our lives and the lives of others. As well, literature can enrich our lives, helping us to encounter ‘other worlds’, languages and experiences that are not within our lived experience. Finally, literature can transform us as language users, learners and people and present us with a different view of the world and our place in it. But as digitisation and new forms of communication change, will how we read and how we access and share books with one another also change? Finally, how might we sustain libraries and other spaces that readers frequent as ‘real’ communities where lovers of books dwell?  相似文献

This research aimed to develop core competencies framework for information professionals of Thai academic libraries in the next decade (2010–2019). The study consisted of two phases, Phase 1- the study of opinions about the roles of Thai academic libraries and information professionals in the next decade (Tanloet & Tuamsuk, 2011) and Phase 2- the development of core competencies framework conducted by using the Delphi technique. This paper presents Phase 2 of the study. The research conceptual framework on core competencies for information professionals was synthesized and adopted from several resources including [Gulati and Raina, 2000] , [Gorman and Corbitt, 2002] , [Abels et?al., 2003] and [Ashcroft, 2004] and University of Nebraska-Lincoln Library (2007). The subject of this small Delphi study included 21 experts from the following three groups: eight instructors of library and information science, eight administrators/practitioners of academic libraries, and five scholars who have had active roles in the library and information professionals. Data were collected in three rounds and analyzed by using the median, mode, and inter-quartile range. Results of the study were concluded and discussed on the three following core competencies for information professionals of Thai academic libraries in the next decade. 1) The Knowledge - consists of eight areas including knowledge of the foundations of information profession, information resources, information and knowledge management, information technology, library and information services, organizational management, research and user studies, and continuing education and lifelong learning. 2) The Skills – consist of 11 skills including user services, information resource management, information technology, marketing, language and communication, team working, analytical thinking, problem solving and decision making, management and planning, teaching and training, conceptual thinking, and knowledge management skills. 3) The personal attributes – consist of seven characteristics including the leadership, service mentality, morals and professional ethics, achievement motivation, accountability, self-management and adaptability.  相似文献
