Scopus™: The Product and Its Development

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.     

Students' Viewpoint: What Constitutes Presence in an Online Classroom?

In this exploratory study, a community of inquiry framework was used to investigate students' perceptions of the efficacy and quality of online information organization and abstracting and indexing classes. It was found that participants valued not only the flexibility of online education, but also the instructor's timely engagement and reflection. Study participants emphasized the necessity of the instructor's frequent engagement through various modes of communication, such as virtual and face-to-face office hours and email. Participants' interest in asynchronous instruction mode was also observed. These findings are in line with previous studies emphasizing the importance of teaching presence in online classrooms. This study contributes to understanding students' perceptions of the quality of online learning and teaching.

中文自动文摘在搜索引擎中的应用

将自动文摘应用与搜索引擎系统,可以使用户更方便、直观地了解被命中网页的内容。本系统在实现基于网页的自动文摘时,针对Web文本的特点,采用了以统计为基础,统计和规则相结合的自动文摘生成策略,实现了HTML标记加权处理、中文文本切分和同义词分析,在此基础上完成了基于统计的文摘句初步提取和基于语用规则的进一步处理。     

基于文献结构的自动文摘的初探

首先阐述了人们进行自动文摘研究的必要性，并介绍了自动文摘的技术背景。然后着重论述了基于文献结构的自动文摘的特点和实现方法，并对已有的数学模型进行评价，提出了作者的一些改进想法。指出了传统自动文摘方法的缺陷，并根据基于文献结构的自动文摘的特点提出了解决问题的办法。本文在最后还探讨了自动文摘在“知识发现”和文本信息挖掘领域内的初步应用。     

批量填表及编写摘要与目录的自动化实现

隐喻与语用预设

预设触发语是实现语用预设的基本手段。它可以是一个词、一个句子也可以是一种句法结构。本文从三个方面讨论隐喻也是一种预设触发语。首先,以Fauconnier的空间映射理论为基础,分析隐喻的工作机制,证明隐喻之所以能实现语用预设,主要是因为它通过空间投射使语言在使用过程中把那些形式上非已知的、非共有的信息变成已知的或共有的,从而隐蔽地向受话人传达信息。其次,隐喻预设也能经得起真假值的判断和“否定测试法”的检验。最后,作为一种预设语,隐喻预设具有其他类型预设所具有的全部特征。
