10、itespace CiteSpace 始開發(fā)于2004年9月13日，于2007年3月20日最近更新(CiteSpace2.0.11b) 由美國德雷克塞爾大學（費城）信息科學與技術學院（The College of Information Science and Technology, Drexel University）Chaomei Chen教授研究開發(fā)。 Chaomei Chen教授研究的Information Visualization CiteSpace是近幾年來在全美信息分析中最具有特色和影響力的可視化信息軟件。從2000年至今，在這一研究領域中Chaomei Chen 教授發(fā)表了研

11、究論文65篇，出版了6部研究專著?，F(xiàn)擔任美國Information Visualization期刊的總編。CiteSpace是Java的應用程序，可免費獲得使用。 http:/cchen/citespace/download.html它要求JRE1.4.2或是更高的版本作為運行環(huán)境。盡管CiteSpace能夠通過 PubMed 或者大量的網(wǎng)絡服務獲取額外的信息，但是互聯(lián)網(wǎng)對CiteSpace而言并不是必須的。citespace輸入的數(shù)據(jù)文件應該是ISI輸出的格式，即從web of science下載的格式。citespace帶有一個數(shù)據(jù)轉(zhuǎn)換器，可以將從網(wǎng)絡上保存的數(shù)據(jù)進行轉(zhuǎn)換。軟件運行之前的基

12、本步驟：1.為citespace準備數(shù)據(jù)。將數(shù)據(jù)文件放在一個文件夾。每個數(shù)據(jù)文件名必須以“download”開頭，并以“.txt”結(jié)尾，例如“download-mass-extinction-2006.txt”2.開始用citespace創(chuàng)建一個新的項目之前，你需要具體制定兩個路徑，一個是數(shù)據(jù)存儲路徑，一個是項目存儲路徑，在項目存儲路徑可以找到你保存的圖譜和輸出文件。3.根據(jù)相應的時間分段調(diào)整time slicing 。4.按“GO”按鈕，你就會看到軟件處于運行狀態(tài)，當運行過程結(jié)束的時候你會發(fā)現(xiàn)彈出一個新的窗口。CiteSpace相關名詞術語Thresholds selection crite
