浅谈CNMARC著录中应注意的几个问题

论述了使用CNMARC过程中应注意的几个问题，其中包括101字段、105字段，200字段，4-字段、701字段几个部分。     

重视具有检索意义字段的录入

以OPAC为途径把具有检索意义的字段分为两大块:一块为读者使用的,一块为图书馆员使用的,并用简洁的语言分别从2字段-6字段来论述具有检索意义字段的录入技巧及如何把一些没有检索意义的字段从简。     

关于CNMARC中7--字段的录入问题

目前我国编目界对CNMARC中7--知识责任者块各字段的录入存在较大分歧.本文对该块的字段设置、录入分歧产生的原因及其表现进行了深入分析,认为必须统一7--字段使用分歧,它对实现机读目录完全标准化及联机编目具有重要意义.     

CNMARC格式的604和605字段录入问题释疑

通过对CNMARC格式的604和605字段的异同点分析,指出国家图书馆与CALLS在这方面录入的差异,供其他编目人员和机构在使用这两个字段时参考.     

机读目录中200字段的讨论

本文针对图书馆题名及责任者著录的复杂情况，探讨了使用CN－MARC格式著录的方法，着重分析了200字段与相关字段的对应问题。     

CNMARC格式的604和605字段录入问题释疑

论文通过对CNMARC格式的604和605字段的异同点分析,指出国家图书馆与CALLS在这方面录入的异,以供其他编目人员和机构在使用这两个字段时参考.     

MARC字段使用频率统计对编目发展和文献检索的启示

通过对1997和2003年书目数据库MARC字段使用频率的统计及对比,分析了字段使用频率及字段内容变化的原因,讨论了编目发展对MARC字段使用的影响和意义,提出字段使用的变化对文献的检索点提供的重要性。     

关于USMARC041字段的若干问题及解答

USMARC是美国国会图书馆早期研制的一种机读目录格式,USMARC格式中的041字段和CNMARC格式的101字段都属于语种著录字段。作者通过工作实践对这两个字段进行比较分析,并解答了实际工作中经常遇到的问题。USMARC041宁段作为著录西文文献语种有则必备的字段容易被漏著或错著。因此,使用USMARC041字段著录时需注意与041相关字段的前后对应关系,041字段第1指示符著入时易发生的误判情况,除$a子字段外的其它子宁段的标识。     

对46—字段编目存在问题分析

46-层级为专用于不同层级记录连接的字段,多用于丛书编目中,在多卷书著录中也偶有所见。在使用46-字段编目中的常见错误有两点:一是没有编制被连记录,致使其最擅长的记录连接作用无从发挥;二是错误地认为该字段能为其嵌套的题名生成检索点。     

试析540字段的作用

从540字段与517字段的区别入手,分析540字段不可替代的作用,并论述有关540字段的各种著录.参考文献2.     

Finding their way: How public library users wayfind

A multi-method case study research design, guided by Passini's conceptual framework of wayfinding, was employed to investigate library user wayfinding behavior within the entry area of a medium-sized public library facility. The case study research design included document review of the library's wayfinding information system; unobtrusive observation of library user wayfinding behavior; intensive interviews with library users to discuss their views on wayfinding in the library; and an expert review with library staff and a library wayfinding and signage expert to validate research findings. Overall, the study found library users' wayfinding behavior to be generally inconsistent over time, but that there are users who stick to predominant segments (those segments used heavily to connect two particular nodes, or stops). Those segments tend to be the straightest or most direct segments connecting two given nodes. Also, users appear to employ Passini's wayfinding styles more often than his wayfinding strategies, but additional research is needed that delves more deeply into these cognitive processes.     

Broadcast profitability: A comparison of profits from broadcast and non‐broadcast segments of public corporations

To understand the broadcast segments of multi‐industry companies, it is important to consider the revenue demands of their parent companies. This article develops a methodology for analyzing the profitability of broadcast and non‐broadcast segments and applies that methodology in an examination of publicly held corporations.     

基于虚词停顿的中文分词消歧研究

提出一种基于虚词停顿的中文分词消岐的模型。首先利用建立的虚词知识库对文本进行粗分词-划分停顿,然后对句子中停顿间的短语用双向最大匹配再进行分词,提取歧义部分,最后使用N-Gram模型和数据平滑等技术处理。整个过程分为粗分词、精分词和歧义消除三个过程。测试结果显示,该模型能有效地降低词歧义引起的错误切分率。     

Concentration and Economics of Multiformity in the Communication Industries

Concentration within, and across 14 segments of the communication industries were assessed by analyzing data over a 5-year time frame. Within-industry concentration continues to increase across a number of segments in the communication industries. Economies of multiformity are introduced by the authors as a way to examine across-industry concentration. Data analysis indicates that across-industry concentration has not yet reached levels indicating high concentration, suggesting further expansion is possible by media conglomerates.     

国家两大联合编目中心CNMARC数据对比研究

国内两大联合编目中心CNMARC数据差异的研究，目前只涉及对其中个别字段的对比分析，而本文对国家图书馆联合编目中心和CALIS联机合作编目中心的CNMARC数据进行系统的对比分析，指出两大编目系统在CNMARC字段的选取、字段著录内容等方面存在的较大差异，并举例分析，提出两家编目中心数据差异产生的原因及解决措施。本文提出的观点对我国实现文献信息资源共享起积极作用。     

CALIS联合编目数据3XX字段的正确使用及其与国图数据3XX字段的比较

在CALIS编目工作中,相对于检索字段而言,3XX附注字段一直是比较薄弱的环节。实际上,要想真正实现CALIS数据“整体化、标准化、规范化”的目标,就必须十分重视3XX字段的著录规则。本文对CALIS3XX字段中容易混淆的几个字段进行分析探讨,概括归纳出正确使用这些字段的一些规律和方法。     

Air Mail: NPR Sees "Community" in Letters From Listeners

This study of National Public Radio's "letters from listeners" segments applies two theoretical frameworks–imagined community and news work–to suggest that the practice of "imagining community" is a distinct practice of journalism. The findings suggest that NPR producers use letters segments to encourage listeners to feel as if they are part of a community. In selecting and packaging those comments, producers construct an imagined community that reflects the producers' own journalistic values, such as balance, accountability, and accuracy. The conclusion suggests that community-imagining might be especially difficult and abstract for large news media organizations serving massive and dispersed audiences.

A Network Analytic Approach to Audience Behavior and Market Structure: The Case of China and the United States

This study adopts a network analytic approach to understand media audiences in relation to media markets, bridging the literature on audience behavior and media economics. Using audience data in the Chinese and U.S. markets, we apply multi-level measures to compare audience fragmentation patterns, a key indicator of market structure, across television channels. Drawing on McQuail's four–stage fragmentation model, we find the Chinese television market exhibits the Core-Peripheral model where a few channels dominate the marketplace and the rest are viewed by niche segments of the audience. In contrast, the U.S. market represents the Pluralism model with extremely high levels of audience duplication across channels, suggesting overlapping patterns of exposure throughout the market rather than isolated segments.
