网络图像检索行为与心理研究 总被引：3，自引：3，他引：0
鉴于国内图像检索行为研究的缺乏,借助用户实验和行为观察技术,采集用户的网络图像检索过程,从检索入口选择、关键行为分布、行为状态变换等不同角度描述用户网络图像检索的行为和心理。研究发现：(1)行为特征上有四类典型的图像检索行为策略、两种行为倾向和五种高频行为模式;(2)用户心理特征上主要表现为定势心理、较少的认知负担以及检索变换的心理阈值等方面;(3)与一般网络信息检索行为相比,图像检索行为既具有共性,又有一些个性特征。图1。表3。参考文献26。 相似文献

[目的/意义] 探讨高校图书馆用户在使用图书馆OPAC系统查找相关资源时调整提问的行为模式。[方法/过程] 以北京师范大学图书馆OPAC日志数据为对象,采用S.Y.Rieh与Xie Hong提出的提问调整模式类型,利用内容分析法对提问日志进行内容编码和统计分析。[结果/结论] 高校图书馆用户的OPAC提问调整基本模式与网络信息检索提问调整模式基本一致,并且,在动态调整模式过程中,还可以细化为直线、阶梯、锯齿、凹凸、循环等子模式。针对如何优化OPAC系统和提升用户信息素养提出若干建议。 相似文献

[目的/意义] 探讨用户在公共检索和非公共检索计算机上进行OPAC检索的行为共性与差异。[方法/过程] 以北京师范大学图书馆OPAC日志数据为例,对图书馆内公共检索计算机和馆外典型非公共检索计算机产生的日志信息进行分析,从基本特征、一次检索会话内的检索行为特征两方面,对两类计算机用户的OPAC检索行为进行比较。[结果/结论] 公共检索计算机用户与非公共检索计算机用户在关键检索行为的表现上具有高度的一致性,包括检索点与高级检索功能的使用、一次检索会话内的提问调整方式等。同时,两类用户在一次检索会话的提问次数、持续时间、两次检索会话时间间隔等方面表现出差异。 相似文献

中文搜索引擎事务类检索的有效转换是在网络检索分类的基础上,以用户事务类检索提问为研究对象,对其形式特点、需求类型、表达方式和组成要素等进行多维度的分析。提出利用词汇控制等手段,通过编制要素词表、提问要素加权的方式来实现检索转换,将检索需求表达不确切或不适合现有搜索引擎检索匹配策略的检索提问转换成更有效的检索提问。 相似文献

关于“手工检索策略”的初步研究 总被引：1，自引：0，他引：1
一、何谓“手检策略”在进行计算机情报检索时,在一定的数据库质量与系统功能的前提下,检索策略构造的好坏,直接影响到相关文献的查全率和查准率,关系到机检服务的效果。那么,在手工检索的条件下,也存在着检索策略问题。例如:针对某一情报提问,需要弄清楚其真正所要求的检索角度、检索深度与广度,需要选择适合于这一情报提问的检索工具;需要确定从何种途径入手、使用什么索引;需要确定该查什么类目、该用什么主题词或关键词;并且需 相似文献

This article surveys a sample of sources of the information about Romania available to British readers in nineteenth century British newspapers and periodicals. It traces first contacts between the Romanian lands and Britain after the union of the principalities of Wallachia and Moldavia in 1859, then after their independence from the Ottoman Empire. The article highlights an increased Romanian interest in British periodicals, which reported and reviewed Romanian literature and scholarship. The article concludes that nineteenth century British newspapers and periodicals offer a great variety and wealth of new material previously unavailable or unknown to researchers. It also states that only a portion of a large quantity of this material has been indexed and is therefore available via the bibliographic sources mentioned in the article. The author argues for the need of a new and updated British-Romanian bibliography, which can draw on new online resources offering access to thousands of new newspapers and periodical records. 相似文献

ABSTRACT The paper looks at library approval plans for material published in Slavic, East European, and Eurasian countries from the selector's point of view. Reasons why a selector would or would not want one are examined. Success with approval plans requires monitoring receipts, as well as good and ongoing communication among the selector, the acquistions department, and the vendor. A preliminary list of vendors offering approval plans for the countries of the region appears in the appendix. 相似文献

ABSTRACT The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed. 相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire. 相似文献

ABSTRACTIn today's current political environment raising support for millage renewals, bond campaigns or even millage continuations for public libraries is affected by national politics, and a tendency towards tax aversion on principle across the country. The lessons we can learn from the governing boards of small and rural public libraries are worth raising up to a greater national consciousness. Board governance, community consciousness, and facilities management are clear and logical tools that elected boards of public libraries can use to politick for support of libraries. 相似文献

Chromebooks and the G Suite group of products, like Google Search, Gmail, and Google Docs, have rapidly expanded in American schools during the past 5 years. The impact of one-to-one Chromebook devices and the pervasive use of Google's software products in American education cannot be overstated. This article explores some of the influences of these products on research, based on the experiences of a librarian and technology coordinator at an elementary education level. The author has several suggestions for effective research with these products in mind. 相似文献

ABSTRACT The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs. 相似文献

Library historians can learn a great deal from studying the gender of authorship and institutional affiliation of a scholarly journal. The focus of this study is to examine these two aspects of journal production in library history to see who is producing published research in this field. Twenty-three years of Libraries & Culture were chosen as the target volumes. The study reveals that more men than women published in library history as well as locating which institutions were represented. This type of information is usedful to the library historian engaged in the analysis of published scholarship, and more generally to scholars with an interest in patterns of literature production in fields closely related to the social and behavioral sciences. 相似文献
