Homepage,cluster.cis.drexel.edu/cchen/citespace,31,CiteSpace,始开发于,2004,年,9,月,13,日，于,2007,年,3,月,20,日最近更新,(CiteSpace2.0.11b),由美国德雷克塞尔大学（费城）信息科学与技术学院（,The College of Information Science and Technology,Drexel University,）,Chaomei,Chen,教授研究开发。,32,Chaomei,Chen,教授研究的,Information Visualization,CiteSpace,是近几年来在全美信息分析中最具有特色和影响力的可视化信息软件。,从,2000,年至今，在这一研究领域中,Chaomei,Chen,教授发表了研究论文,65,篇，出版了,6,部研究专著。现担任美国,Information Visualization,期刊的总编。,33,CiteSpace,是,Java,的应用程序，可免费获得使用。,,cluster.cis.drexel.edu/cchen/citespace/download.html,它要求,JRE1.4.2,或是更高的版本作为运行环境。尽管,CiteSpace,能够通过,PubMed,或者大量的网络服务获取额外的信息，但是互联网对,CiteSpace,而言并不是必须的。,34,citespace,输入的数据文件应该是,ISI,输出的格式，即从,web of science,下载的格式。,citespace,带有一个数据转换器，可以将从网络上保存的数据进行转换。,35,软件运行之前的基本步骤：,1.,为,citespace,准备数据。将数据文件放在一个文件夹。每个数据文件名必须以“,download”,开头，并以“,.txt”,结尾，例如“,download-mass-extinction-2006.txt”,2.,开始用,citespace,创建一个新的项目之前，你需要具体制定两个路径，一个是数据存储路径，一个是项目存储路径，在项目存储路径可以找到你保存的图谱和输出文件。,3.,根据相应的时间分段调整,time slicing,。,4.,按“,GO”,按钮，你就会看到软件处于运行状态，当运行过程结束的时候你会发现弹出一个新的窗口。,36,CiteSpace相,关名词术语,Thresholds,selection criteria used by CiteSpace items must have measures above threshold values to be included in modeling and visualization processes.,Time slicing,a divide-and-conquer strategy that divides a period of time into a series of smaller windows.,Betweenness centrality,a metric of a node in a network that measures how likely an arbitrary shortest path in the network will go through the node.,Burst terms,single or multi-word phrases extracted from the title,abstract,or other fields of a bibliographic record and the frequency of the term bursts,i.e.sharply increases,over a period of time.,Citation,an instance that a publication references to another publication.,37,Co-authors,authors who appear in the author field of the same bibliographic record.,Co-citation,an instance in which two items,such as authors,documents,or journals,that are cited by a publication.,Time-zone view,a restricted view in which the movement of nodes is limited to vertical time zones corresponding to the time of their publication.,Turning points,nodes of high betweenness centralities(1.00).Such nodes tend to be critical in network transitions from one time slice to another.,Cluster view,a network is visualized in a modified spring-embedder node placement algorithm.,Pathfinder network scaling,a network scaling algorithm that removes links that violate triangle inequality conditions so as to simplify a network by retaining salient links and paths only.,38,CiteSpace的简要操作步骤,39,1.Access/Obtain,CiteSpace and how to run,获取和运行,The CiteSpace Homepage,cluster.cis.drexel.edu/cchen/citespace,两种方法运行,citespace,a.Use Java,WebStart,directly,通过网络直接启动,b.,下载,citespace.jar,文件（网页,download,）,方法,a,：能保证始终用到最新版本，且运行速度快,40,2.Prepare Bibliographic Data Files 准备文献数据,从web of science 检索和保存数据方法：,a.Make a general search in Web of Science,b.Mark all search results,c.Save the records,including Cited References,in field tagged format.,d.Name your files as,download*.txt,E.g.downloadScience1999a.txt,download2004.txt,e.Save all data
