現今資訊化社會的時代下，資料累積的速度有著爆發性的成長，使得研究
者能對更豐富廣泛的資料進行研究，但要找出真正所需的內容，也變得更加困
難。在動輒幾十萬篇文章的情況下，如何從大量資料中去蕪存菁，過濾出真正
所要的資料是值得我們探討研究的。
而使用智識結構圖形對大量資料進行透視與分析是一個很好的方式。在目
前大部分有關智識構圖的文獻會使用因素分析，而在因素轉軸的方法上分為正
交與斜交兩派，但卻很少研究解釋為何使用該方法，故本研究會對此議題進行
探討，比較兩種轉軸方式所產生之視覺化效果與分析結果之差異。在比較後發
現，無論從結果的判讀，到總解釋變異量與信度數據。正交轉軸所提供的結果
仍是較好的選擇，本研究建議如果想探討資料本身的相關性時，才需要使用斜
交轉軸所產生的Component Correlation Matrix 來觀察哪些因素之間關連性的存
在。而如果要使用斜交轉軸時，本研究建議使用Pattern Matrix 作為分析使用。
除此之外，智識構圖在驗證正確性上，也有著一定的困難度，故本研究
使用了領域專家對於Information Science 研究中的分類結果作為第一次的驗證，
引述另一位研究分析員對此議題所分析的結果進行二次的驗證，藉此產生更客
觀的結果，再使用信度分析裡常被使用的Cronbach’sα值作為第三次的驗證。
在領域專家的部份雖然沒有與其百分之百的吻合，但本研究所歸類的議題皆有
出現在專家分類之中；而研究員二次驗證的結果與本研究之分類命名類似，可
作為本研究結果分類上的補充；各因素的Cronbach’sα值則皆有達到水準以上，
最後本研究驗證並確定了研究結果確實具有良好的可信度。

The intellectual structure is a widely used method to facilitate the comprehension
of the important research topics and their inter-relationships in a knowledge domain.
The intellectual structure building process derives the structure utilizing the factor
analysis, and the orthogonal rotation of axes used by the Varimax is the most
commonly used option in the factor analysis. However, the assumption of applying
the orthogonal rotation method is the factors are independent of each other. This
factor independence assumption is against our observation in the past since the topics
in a research field are related to each other. We therefore apply the oblique rotation
method used by Promax, which does not assume the independence among factors.
This study compares the factors derived from these two methods in terms of
several indicators and the visual effect. The preliminary results indicate that the
factors derived from the orthogonal rotation and oblique rotation provide
complementary information.
To validate the intellectual structure derived by our study, we take the
classification results given by an IS field expert’s as the benchmark for comparison. In
addition, we also use the classification results derived by another analyst on the same
dataset from another study as an additional support. Cronbach's α value is calculated
to test the internal consistency of factors.
