陈老师,您好。我是一名在校本科生,近期跟老师做一个信息可视化的项目,需要用到您开发的citespace,可我的电脑怎么也启动不了,我已经装了java,但每次启动launch.jnlp时,都会弹出“应用程序错误”的对话框,点击详细信息,会看到——
错误:无法加载资源:file:/C:/CitespaceII/dist/launch.jnlp

不知是何原因,迫切需要的到陈老师您的解答!
陈老师,我在DCA聚类分析中,按步骤做到了Cluster Explorer,但是无法做到像您的著作《The Structure and Dynamics of Co‐Citation Clusters:A Multiple‐Perspective Co‐Citation Analysis》中,从最大的聚类中找到cited references as the Intellectual Base或者Citing Articles as Research Fronts,那些cited reference还有citing article是怎么找出来的?我在cluster explorer中可以找到每个聚类的cluster members还有cluster makers。cluster members中有author但是title下面都是省略号“.....”。cluster makers显示正常,下面的文献是不是应该对应的是citing article呢?谢谢陈老师,我的每步都是在您的指导下完成的,真心感谢您,真想拜您当导师。
我的回复(2011-12-23 21:39):cluster members == cited references == intellectual base
cluster makers == citing articles == research fronts
cited references的title你要逐个找一下,最简单的办法是在网络中找到相应的节点,右键》DOI, 或Google Scholar来找title.
陈老师,我看您的著作《The Structure and Dynamics of Co‐Citation Clusters:
A Multiple‐Perspective Co‐Citation Analysis》中关于ACA的操作,在做出来ACA的timeline图谱之后,表4做的是“labels of the largest ACA clusters”,我知道操作,但后面的表5”top-10 most cited authors of the largest ACA clusters“的具体操作时怎样的,我试了很久都没有试出来,陈老师能告诉我一下吗?我最近在写论文,频繁的请教陈老师真是不好意思,谢谢陈老师。麻烦您了。
六篇文献是:1.Ferretti A,1990.Knee injuries in volleyball 2.Ferretti A,1992.Knee ligament injuries in volleyball players 3.Lian O,1996.Characteristics of the leg extensors in male volleyball players with jumper’s knee 4.Briner WW,1997.Common injuries in volleyball 5.Bahr R,2003.Injuries among word-class professional beach volleyball players 6.Ferretti A,1998. Injuries of the suprascapular nerve at the spinoglenoid noth
基本上都是关于伤病的,我数据的主题是“volleyball”。我试了很多次,一直是这种情况,不知道该怎么分析了!麻烦陈老师了。谢谢您!
陈老师,您好,我在分析web of scienc数据的过程中,做了文献共被引的图谱,年份是从1982年到2011图谱中有六个关键点,我查看了六篇原文,但是我发现这六篇文献的范围局限在1990年到2000年之间,并且都是关于一个主题(injuries),但是我得数据是以“体育”为主题搜索的。我看到您的文章中认为,共被引网络能够反映研究前沿的发展轨迹,那么像这样的数据的研究前沿就一直是“injuries”吗?我该怎么分析呢?麻烦陈老师百忙之中抽空帮我解答一下,谢谢陈老师。
我的回复(2011-12-19 11:57):tfidf = tf x idf = term frequency by inverted document frequency
LLR = log-likelihood ratio
MI = mutual information
