SUMMARY At the Archives Départementales des Pyrénées-Atlantiques, the encoding of more than forty legacy finding aids written between 1863 and 2000 is part of a program of digitization of the collections. Because of the size of the project, an external consultant, ArchProteus, has been brought in and specific management procedures have been put in place within the institution. The conversion has allowed the testing and verification of the flexibility of the EAD DTD, despite the various hurdles negotiated throughout the project, such as the necessity of reengineering finding aids, and standardizing index terms, etc. It becomes clear that a conversion project–in this case, a retrospective conversion–will lead the archivist to rethink the production of finding aids and the relationship with users and patrons. 相似文献

ABSTRACT Scopus is a new all-science abstracting and indexing (A&I) database. It is the result of a two-year collaboration with librarians and researchers from all over the world. Scopus covers over 14,000 scientific, technical, medical and social science titles from 4,000 publishers. It offers new sorting and refining features so that researchers can easily find and access more than 27 million abstracts and citations stretching back to the mid-1960s. This article recounts the development of Scopus from its inception in 2002 to its success in securing over 100 customers within weeks of its recent launch. The story is told by one of the librarians heavily involved in testing and shaping the product and by one of the Product Managers who built it. 相似文献

This study concerns the overlap between author-supplied keywords and Library of Congress Subject Headings (LCSH) in Electronic Thesis and Dissertation (ETD) bibliographic records in the library catalog. The article provides a discussion on uniqueness, matching, and complementariness based on a replication of Strader's methodology and rubric from a 2009 article. Findings support most of Strader's conclusions, including the complementary nature of keywords and controlled vocabularies. Both keywords and LCSH provide unique terms that enhance access. Researchers also broke new ground regarding partial matching, particularly within LCSH. The fact that uniqueness matters has implications for the continued use of LCSH, for LCSH maintenance, and for further research. 相似文献

Library catalogs do not provide catalog users with the assistance they need to easily and confidently select the person they are interested in. Examples are provided of Web services that do a better job of helping information seekers differentiate the person they are seeking from those with similar names. Some of the reasons for this failure in library catalogs are examined. This article then looks at how much information is necessary to help users disambiguate names, how that information could be captured and shared, and some ways the information could be displayed in library catalogs. 相似文献

学术论文英文关键词标引存在类似于中文关键词的不能反映主题概念、通用词过多、词序不当等问题,还存在简洁性不强、缩略语过度使用、词形不当、译写不当或错误等问题,导致英文关键词检索质量较低。控制英文关键词标引质量不能仅限于数据库专职标引人员的主题标引,还包括社会或学术团体控制、编辑控制、作者控制等3个方面。 相似文献

从关键词与高频词的相关度看自动标引的可行性 总被引:1,自引:0,他引:1
本文通过基于词频统计的内容分析法,将从文本中抽取的高频词与关键词进行匹配对比;根据抽样实验的结果分析了二者的相关度,并以此为基础论证了文献主题自动标引的可行性;结果证明当高频词取到第3位时便能与人工标引的关键词达到一半以上的匹配,在取到7位时便能在85%的程度上替代人工标引. 相似文献
