Data Visualization as Participatory Research: A Model for Digital Collections to Inspire User-Driven Research     

A. Miller 《Journal of Web Librarianship》2019,13(2):127-155

The emerging creative practices of digital collections are increasing in prominence thanks to the access to, and appeal of, data visualizations. Interactive data visualizations, such as a map, timeline, chart, graph, or artist’s rendering of data, enable users to pursue their own research interests within a collection and participate in new areas of research. Use of these data visualizations enhances the scope of the collection and enables a modern and diverse thematic collection to emerge. This article considers the question: Does the addition of data visualizations affect how users participate with a research collection? Impacts on collection development, application of user-centered design, and analysis of users’ exploratory strategies are discussed. Examples of data visualizations used in digital humanities projects and digital collections are presented as case studies.  相似文献

基于信息可视化技术的文本聚类方法研究   总被引：4，自引：0，他引：4  

杨峰  周宁  吴佳鑫 《情报学报》2005,24(6):679-683

信息可视化是信息管理和信息系统的热点研究问题。随着网络技术的发展,充分有效地利用丰富的文本资源成为人们关注的焦点。文本聚类是处理文本的重要方法之一。本文在分析现有文本聚类方法的基础上,结合可视化技术解决该类问题的一般过程,给出了一个基于非线性映射实现的可视化技术进行文本聚类的方法,并通过案例说明该方法的特点,指出它与目前流行方法的不同以及其优势所在。  相似文献   

国际学科教学知识的文献计量研究     

徐金雷 《课程.教材.教法》2018,(3):132-138

学科教学知识(PCK)自舒尔曼1986年提出以来,受到了广泛关注。通过在Web of Science核心合集中对"PCK"进行文献计量研究,辅以CiteSpace进行关键词共现等分析,可以从整体上了解国际PCK的研究现状、研究热点与研究前沿问题。通过分析发现,在研究方法上,文献计量方法的综合使用有利于形成科学而准确的结论;在研究内容上,国际PCK的研究热点与研究前沿特征词较相似,体现了创新研究的不足。  相似文献

The powerful image and the imagination of power: the ‘new visual turn’ of the CPC’s propaganda strategy since its 18th National Congress in 2012     

Jiang Chang  Hailong Ren 《亚洲交流杂志》2018,28(1):1-19

This paper adopts the academic tool of discourse analysis to examine the ‘new visual turn’ of the Communist Party of China’s propaganda work since the 18th CPC National Congress when Xi Jinping was inaugurated as the leader of Chinese Communists. A thorough review of the new visual means the Party uses for photojournalism, TV news, animated cartoons and online promotional videos points to three developments markedly different from traditional discursive strategies: a full embrace of Confucian ethics, articulation of the Internet-based popular culture and subcultures, and an effort to fortify Xi’s personal authority as a political idol. The paper concludes that the ‘new visual turn’ of CPC propaganda after the 18th Party Congress suggests that the Communist discourse has evolved to a new stage where sophisticated manipulation of sleek technological tools substantiates a rigorous, dynamic CPC discursive system more at ease with itself and more powerful than ever in shaping the mainstream political culture in China.  相似文献   

Assessing library topics using sentiment analysis in R: a discussion and code sample     

Brady D. Lund 《Public Services Quarterly》2020,16(2):112-123

Abstract

This article discusses the use of R programing language for executing a sentiment analysis of tweets pertaining to library topics. This discussion is situated within the literature of marketing and management sciences, which is employing methods of machine learning and business intelligence to make informed decision-making, and library administration, which has expressed great interest in social media engagement within its literature but has yet to adopt these types of analysis. Presented in this article is a sample code with instructions on how users may execute it within R to retrieve and analyze tweets relevant to library services. Two examples created using the code (analysis of top librarians’ tweets and analysis of posts about major book publishers) are used to demonstrate the functionality of the code. The code presented in this article may be used by libraries to analyze tweets about their library and library-related topics, which, in turn, may inform management and marketing design.  相似文献   

面向数字人文研究的大规模古籍文本可视化分析与挖掘   总被引：2，自引：1，他引：1  

欧阳剑 《中国图书馆学报》2016,42(2):66-80

传统的古籍开发与应用模式已难以适应人文学科研究的需要,人文学科研究者期待一个技术逻辑和人文逻辑相耦合的数字人文研究范式的出现。本文从古籍文献深层次开发与利用出发,利用新的信息技术与面向数字人文研究跨学科方法,以大规模中国古籍文本为研究对象,采用大数据研究理念,对古籍进行整理、标注、自动分词等处理,以词频分析统计为研究核心,采用数据降噪、基于窗口时间单位的统计分析计算、滑动窗口预测等分析与挖掘方法,采用大数据实时分析技术,实现了实时、在线、立体、可视化、定量分析字词的历史词频分布规律,创建了一个以语言学、历史文献学、历史地理学等人文学科研究为主的古籍实时统计分析平台,可辅助研究者在大量的古籍文献中发现新的模式、现象、趋势等,实现古籍开发与应用模式创新的初步尝试。图11。参考文献36。  相似文献
