深入开展中华人民共和国国史的教育和研究一直是各方高度重视的工作。将国史知识进行语义揭示和组织,对于国史的教育和研究具有重要意义。在参考相关研究成果的基础上,本文提出了“向下挖掘,向上组织”的国史知识语义揭示与组织方法。这一方法以国史本体为基础,在对隐藏于国史资源文本条目中的国史知识对象和相关事实进行语义挖掘和揭示的基础之上,通过国史知识对象的关联,构建国史知识网络,并基于时间、类属、层级及统计等关系,对国史知识内容进行更高层次的多维组织展示,并基于这一思路开发了相应的系统平台,实现了国史知识的揭示、重组和其他创新应用。本文所提出的国史知识语义揭示和组织方法对其他类型知识的开发利用具有参考价值。图7。参考文献12。  相似文献

图书馆、档案馆、博物馆的藏品有相似之处,三馆的保护目标、保护原则、保存手段、利用方式、保管设备、修复技术、工作流程等也有很多相似之处,面对三大领域长期以来因体制隔阂而导致人才分别培养、研究独立进行等局面,文章对图书、文物、档案保护的学科整合问题进行探讨,试图构建一个由"藏品—藏品保护分类技术—人"三个维度构成的专业人才培养体系,进一步推动图书馆、档案馆、博物馆事业的发展.  相似文献

ABSTRACT

Boundary walls are neglected but important parts of historic urban environments, and they are often prone to serious deterioration. Understanding moisture and salt dynamics within boundary walls can help infer the causes and dynamics of deterioration. This investigation investigates the patterns of moisture, salt, and deterioration on a 300 year old limestone boundary wall in Worcester College, Oxford. Multiple methods to assess moisture and salts within and across the wall (electrical resistivity tomography, handheld resistivity-based moisture meter, paper pulp poultices, scanning electron microscopy, inductively coupled plasma optical emission spectrometry, and ion chromatography of small scale sampling of deteriorated limestone) were used in conjunction with decay mapping of both sides of the wall. The salt weathering strongly correlates with severely weathered zones at the wall and salts, mainly sulfates, seem to be the main agent of decay processes. The combined results demonstrate that the environmental influences driving stone decay can differ on a very small scale even at a comparatively simple structure like a boundary wall, and that repairs can have adverse effects if the patterns of salt and moisture dynamics are not sufficiently known.  相似文献

The rehabilitation of physically disabled persons is an expanding and interdisciplinary field, and the literature on this topic has grown rapidly in recent years. Bibliographic control of rehabilitation literature is poor, and selection of materials about physically disabled persons can be a difficult undertaking. The present article describes and evaluates various selection tools on the basis of their coverage of rehabilitation literature and their usefulness to academic, public, and special librarians.  相似文献

SUMMARY

This article examines what is implied by the term “trusted” in the phrase “trusted digital repositories.” Digital repositories should be able to preserve electronic materials for periods at least comparable to existing preservation methods. Our collective lack of experience with preserving digital objects and consensus about the reliability of our technological infrastructure raises questions about how we should proceed with digital-based preservation practices, an emerging role for academic libraries and archival institutions. This article reviews issues relating to building a trusted digital repository, highlighting some of the issues raised and possible solutions proposed by the authors in their work of implementing and acculturating a digital repository at Rutgers University Libraries.  相似文献

[目的/意义]数字时代的图书馆一直在面对层出不穷的竞争者,也一直在流失用户。新一轮互联网浪潮中的知识付费成为图书馆最新的竞争者,但相关研究尚未注意到知识付费在社会知识交流中的角色与影响,也没有更进一步地再回到对图书馆事业影响的思考上去。[方法/过程]使用比较法和历史研究法,以知识付费的兴起与局限为参照展开分析。[结果/结论]知识付费兴起的原因是丰富的人才资源和扁平化的知识交流市场,当代图书馆地位受到挑战的背后是图书馆员职业主体性消解和中介性消解。图书馆应当放弃"中心"思维,重新认识现阶段的历史任务,通过图书馆和图书馆员的专业性输出来重申价值与回应挑战。知识付费尚存在不能解决信息失真和阻碍信息公平两大局限。与其他知识交流市场的竞争者相比,当代图书馆仍然具有不可替代的独特价值。  相似文献

The vast majority of America's cultural/ethnic/linguistic minorities are found in the nation's 50 largest cities. The problems that will eventually be faced by all communities are being confronted in these large cities first. While there are many problems, there are also a number of encouraging trends. Suggestions for continued improvement are made.  相似文献

随着上海在全球语境中的迅速崛起,越来越多的电影将上海作为故事发生的地域背景搬上大银幕,有些影像表达确实程度不同地揭示了上海的空间变化和文化态势,但有些则是借助上海国际都市的全景视野暗藏作者个人的社会批评和文化观点,或是完全凭一己想象为上海贴上不合逻辑的身份标签。文章就此来阐释全球化语境下对上海自由抒写"想象能指"的可能性并对上海的影像表达做出反思。  相似文献

The National Digital Information Infrastructure and Preservation Program (NDIIPP) was initiated in December 2000 when the U.S. Congress authorized the Library of Congress to work with a broad range of institutions to develop a national strategy for the preservation of important at-risk born digital content. Guided by a strategy of broad collaborations and iterative learning, the Library of Congress began catalyzing a national network of partners dedicated to collecting and preserving important born-digital information. Over the last six years, the Library and its partners have been engaged in learning through action. Our investments in preservation partnerships, public policy deliberations related to intellectual property challenges, basic technical research, and network architecture models have increased our understanding of the sustaining roles and functions for a national network of diverse stakeholders. The emerging network of networks is complex and inclusive of a variety of stakeholders: content producers, content stewards and service providers from the public and private sectors.  相似文献
