在图书馆编目实践中常常存在着著录差异问题,其中丛书、多卷书的著录差异最大。结合Interlib图书馆集群管理系统的检索特点,图书馆可通过在编目细则上规定取消225丛编字段、4--款目连接块字段来简化丛书、多卷书的著录,并以ISBN异同作为集中、分散著录的主要依据,规范多卷书著录方法,以易于编目人员的理解及操作,减少人为因素造成的误差,进而满足读者的检索需求。 相似文献

实际工作中,在对丛书著录时,许多编目机构对于机读目录格式中头标区与丛书有关的代码以及丛书项225字段的指示符,连接款目块的461、462等字段运用的比较混乱。主要表现形式为:未能区分记录头标区中"nam#"与"nam0"的区别;丛书225字段指示符使用中存在误区,没有正确表达"2252#"和"2250#"的区别与联系,"2251#"的用法也不准确;在检索点与记录连接、丛书名的规范等方面也存在随意性。文章对上述问题进行了分析,利用实例说明应正确著录的方式。 相似文献

随着图书出版业的日益繁荣,以丛书形式出版的图书越来越多。而关于丛书的著录,目前在理论认识上还存在着诸多分歧,在编目实践中不同图书馆和不同编目员也往往各行其是,这直接导致了各馆丛书编目数据的混乱,出现了诸如记录头标的取值、225字段指示符的选取、连接字段使用的有效性、多于两层的丛书著录等方面的问题。 相似文献

目前我国图书馆界对中文译著的著录方法还没有取得共识,其中对原文题名的著录更是存在较多问题。通过对已有的几种中文译著原文题名的著录方法的比较分析可知:原文题名属于并列题名的,需用510字段作检索点,但可不著录200字段的$d子字段;原文题名不属于并列题名的,宜用517字段作检索点;对于中外文数据混合建库的图书馆,可使用454字段作连接,否则可以不著录454字段。 相似文献

在编目规则国际化的趋势下,统一编目著录规则已经成为国内编目界的当务之急。目前,CALIS和中国国家图书馆两家中心馆的编目著录规则存在一些不同,一些有识之士已经对此提出己见,但却遗漏了丛编项著录的差异。尤其是当丛编项作为重要的著录项时,它选取、使用的字段及著录的信息等方面的差异更为严重,给书目数据检索、共建共享带来了不便。因此,CALIS和国家图书馆应该统一思想,争取早日制订出统一的编目规则。 相似文献

Tess M. Gibson Patricia E. Kirkwood 《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2013,23(1):47-56
In fiscal year 2004–2005, papers published in the Material Research Society's Proceedings series were the fifth most requested interlibrary loan item submitted by faculty and students at the University of Arkansas. This prompted the authors to determine if a purchase-on-demand scheme for items in this series, made without any subject specialist input, would allow the library to increase the strength of its collection at a price that was no greater than or lower than the real cost of traditional interlibrary loan. The study analyzes and describes the parameters of the data. Results suggest that this type of plan might be useful for libraries lacking a designated selector. 相似文献

将自然语言处理技术——统计语言模型引入信息检索领域产生了一系列全新的检索模型,典型包括查询似然模型、生成相关性模型、词项依赖模型、统计翻译模型、泊松分布模型以及风险最小化框架等。本文从统计学模型以及N-gram技术的角度重点解析这些信息检索模型的演进过程。最后对基于统计语言模型的信息检索模型的发展过程以及未来发展趋势和挑战进行了总结。 相似文献

The present study experimentally assesses the relative influence of visual and verbal exemplars on news readers’ judgments regarding use of emergency room health care services by undocumented immigrants and uninsured U.S. citizens. Assumptions from exemplification theory and theories of information processing guided the investigation. A series of two studies found that pictures and personal stories have comparable effects on perceptions of and attitudes about the issue. Furthermore, conflicting personal stories and pictures embedded in the same news item nullify each other's effect. 相似文献

This article explores the growth and character of breaking news on two 24-hour news channels in the United Kingdom, Sky News and BBC News 24. Our purpose is to examine, in detail, the nature and role of breaking news and, more generally, its impact on the quality of television news journalism. We draw upon a series of content analyses of news programming conducted in 2004, 2005/6 and 2007, and compare the elements of a breaking news item with more conventional forms of news. Our findings indicate that “breaking news” has become an increasingly important part of the 24-hour news culture. This growth means that the typical breaking news item is becoming increasingly predictable and routine. Moreover, by most measures, breaking news items are less well informed and feature less independent reporting than conventional news items. As a consequence, we argue, the decision to cover more breaking news stories impoverishes the quality of journalism. 相似文献

This research project focused upon an inconsistency in the structure of a context specific instrument measuring communication apprehension in dating relationships. A parsimonious, single‐factor, solution for Dating Partner Communication Apprehension (DPCA) emerged from the analysis. Principle component analysis produced a 13‐item solution that maintains high reliability and validity. As hypothesized, validity checks indicated that the DPCA unidimensional model was moderately and significantly correlated with dyadic communication apprehension, interpersonal solidarity, interpersonal communication satisfaction, and a series of relational perceptions in the dating context. A variety of potential applications and explorations of communication apprehension within dating relationships are discussed. 相似文献

This paper reports a series of studies that develop an empirically-derived instrument for assessing online communication attitude, a multidimensional set of individual cognitive-affective constructs that influence media choice. The first study inductively develops an initial item pool and tests dimensional structure via exploratory factor analysis. The second study further refines this structure and also tests the association between online communication attitude and media use in same-sex friendships. Finally, the third study deductively tests global model fit via confirmatory factor analysis, and establishes concurrent validity with theoretically related communication constructs. Beyond identifying motives underlying media choice, the instrument developed here possesses heuristic potential for clarifying media choice theory and elaborating the association between communication competence and media choice. 相似文献
