Analysis of a survey of the types and extent of tools and techniques related to semi-automatic metadata generation applied in real-world library settings indicates that practical applications in libraries seem to be at an incipient stage. More than half (n = 149, 52.5%) of the survey participants (n = 285) specify that semi-automatic metadata generation has not been utilized for metadata creation and management in their libraries. This figure becomes even higher when adding the response “don't know,” constituting an additional 13.7%. The results of the survey also show that the semi-automatic metadata generation tools described by participants mostly concern metadata format conversion (38.6%) and metadata templates and forms (27%) for populating certain metadata values. Complex tools and the generation and extraction of metadata directly from the content and context of the digital objects are rarely applied in libraries. This indicates that more research is needed on the development of automatic metadata generation for semantic metadata in usable and practical settings. 相似文献

The U.S. patent system and the body of issued patents are key elements in meeting information needs related to technology and innovation. Most librarians, however, have little understanding of the value of patents as sources of technological information—and less knowledge about how to help users tap what has been called, “the largest and most comprehensive body of technological literature in the world.” This article attempts to provide a sufficient background on patent fundamentals to allow librarians to assist or refer users who would benefit by the use of patents. Detailed patent searching instructions are provided for staff in Government Printing Office depository libraries to use materials available through the depository program. The value of utilizing one of the 58 Patent depository libraries to enhance and expedite the search process is highlighted, and online searching options are introduced. 相似文献

The World Wide Web and other information technologies have deeply changed our information environment and influenced how we index and access the information we need. The library is a good example of this revolution. Instead of a building that holds books, the library is evolving into an electronic portal to digital materials from across the globe. Facing so many distributed and heterogeneous digital resources, layered metadata are efficient but sophisticated tools that make it easier to find the best information resources. In recent years many types of item-level metadata with which people are familiar have appeared. In contrast to item-level metadata, collection level metadata has not been broadly used, especially in China. By illustrating what a collection is and why we should create collection level metadata, we introduce the research and usage of collection level metadata in China and analyze the problems and limitations of the metadata being used. Some suggestions as to its use are also mentioned. 相似文献

In the current information environment, libraries need to leverage on the latest digital technologies as well as the traditional paper technologies towards building practical digital libraries and electronic information systems. Digital libraries built exclusively out of nascent electronic publications such as e-journals, e-books, e-reference works (Web-based training programs, computer-based training programs, etc.), digital scholarly works (monographs, etc. in the public domain) and digitized documents conforming to standard digital formats are proving to be an uphill and unfinished task. Perhaps this could be the major reason why the start-success-finish ratio of most of the digital library initiatives, particularly initiated by isolated/individual libraries, is still left at alarmingly low numbers. We find the motivational and emotional bonding among the stakeholders melting down eventually as the digital library development process gets fired up. There are a host of problems the enthusiastic library fraternity face in their digital library development endeavours starting from copyright issues, technology complexities, infrastructure threats, diverse publication types, multiplicity of digital object formats and above all the publishers’ stringent policies and monopolies. It is therefore essential that the libraries adopt necessary strategies towards developing digital libraries from the lessons learnt. The monolithic and all-in-one-container approach is no longer feasible and no more advocated. It is imperative on the part of the information professional to have a componentized and a multi-system approach to knowledge technologies and information management. Seamless aggregation and meticulous integration of diverse datastreams, embracing the print as well as the electronic information, is the most appropriate strategy to be adopted and applied. This paper shares Indian Institute of Management Kozhikode's experience in creating a state-of-art digital library information system by seamlessly integrating and aggregating the print as well as the diverse and distributed digital content penetrating into its knowledge domain. The paper highlights significant features of IIMK's digital information system—the content aggregation and the content integration strategies we adopted for designing a scholarship Web portal and developing a digital library using the ‘Greenstone’ open source digital library software. The paper also highlights the role of libraries in promoting open access by setting up scholarly institutional repositories (IR). In summary, today's digital library information system is to be seen from a much wider and more holistic perspective, and provided with a much broadened meaning to hold and put together all the print, digital and electronic information available and accessible to the library. 相似文献

This paper discusses some key issues for digital archives and metadata in a networked information environment to keep our community memory for the future. The paper is based primarily on the experiences and lessons learnt by the author from his research activities on metadata and digital archives. The author participated in a study group on digital archives hosted by the Ministry of Internal Affairs and Communications of the Japanese Government from February 2011 to March 2012. The group discussed the promotion of digital archives in Japan, particularly at memory institutions. The Great East Japan Earthquake of 11 March 2011 caused serious damage in the north-eastern part of Japan, especially the Pacific coastal regions. This disaster significantly affected the discussions of the group. The basic lesson that the author learned is that digital archives built on a robust information environment are essential for keeping our community memory safe for the future. Not only do the primary digital resources need to be properly maintained and preserved for the future but also secondary resources, metadata and meta-metadata. We need to use Linked Open Data technologies to enhance the usability of such digital resources in the archives. 相似文献

通过对《书目记录的功能需求》（FRBR）概念模型体系结构中实体、属性及关系这3个基本要素的分析,探寻由FRBR模型抽取出的馆藏资源元数据关联网络的构成要素,并对符合FRBR的馆藏资源元数据知识节点与关联关系所构成的关联网络结构进行层次划分,形成以元数据记录属性为支撑的微观层面关联网络及以元数据记录之间或规范数据集之间关联关系作为支撑的宏观层面关联网络。而词汇集的建立、术语复用机制、数据集链接桥机制成为构建馆藏资源元数据关联网络的基本要素。馆藏资源元数据关联网络的建立对于揭示馆藏资源内部的知识结构、扩展知识检索的范围、推荐关联知识、辅助知识发现等均具有重要的价值。 相似文献

Large scale statewide library cooperation using information technology and wide area networks dates back to the early 1980s with efforts such as the Florida Center for Library Automation and, more recently, the LOUIS Project in Louisiana (see JAL January 1994) and OhioLink (see JAL September 1995). Early efforts were usually focused on the implementation of library information management systems and the provision of shared access to locally held collections, and they often still are. In the 1990s, though, we are witnessing a shift in statewide cooperative use of networks to provide principally access to bibliographic and full-text resources not held locally and usually provided by commercial vendors for use by libraries. As the case studies in this column illustrate the development of funding sources, the technical implementations and support, and the management organization differ from state to state. They reflect, though, the incremental shift in the information landscape towards “electronic libraries”. I choose the word incremental intentionally to reflect that this change has not (at least so far) been anywhere near as rapid or revolutionary as many expected. Nevertheless, what has happened in about 15 years is quite dramatic. It portends a different kind of academic library.—CBL, University of Maryland, College Park. 相似文献
