設計與實作智慧型問卷分析輔助系統

Abstract

當社會科學研究人員分析問卷時，常需要使用一些統計輔助工具，例如SPSS，來協助分析，然而現今這些工具只能給予使用者統計方法運算上的輔助，並沒有提供使用者分析問卷時的決策輔助，例如驗證假設的統計方法的選擇。 在這個研究中，藉由之前我們提出的輔助問卷分析相關的研究。我們設計並且實作一個智慧型問卷分析輔助系統，我們制定了系統設計相關的圖表，讓系統將來能夠方便於擴充以及維護。這個系統使用三種指標器來計算統計上的顯著性差異的程度以及規則來決定哪個指標器有較高的程度有統計上的顯著性差異。我們基於指標器和規則來建立了顯著性差異觀察器。系統也提供了建議關於合適的統計方法來驗證假設以及提供解釋給使用者。系統亦提供了學習教材給使用者學習這些建議的方法。 我們實作了這個系統的原型，並且做了一個個案研究以及使用者滿意度調查的實驗。實驗的結果顯示系統分析出來的結果幾乎正確，而使用者對於系統的概念很感興趣。我們在未來會增加更多有用的功能到系統中。

When social science researchers analyze questionnaires, they often need to use some statistic-related tools, for example SPSS, to assist their analysis. However, nowadays these tools only support users the computation of statistic, they do not support the decision when users analyze their questionnaire. For example, the decision of statistical methods used to verify their hypotheses. In this study, those our previous researches on assistant questionnaire analysis are used to design and implement an intelligent questionnaire analysis assistant system. We formulate the figures for system design to make our system easy to extent and maintain in the future. This system uses three kinds of indicators to compute the degree of statistically significant difference and metarules to determine which indicator having more degree of statistically significant difference. A Significant Difference Viewer is constructed based on the indicators and metarules. This system also provides suggestion for appropriate statistics methods to test hypotheses and gives explanations for users. This system gives the learning materials for users to learn these suggested methods. The prototype of this system is implemented, and the experiments of a case study and the satisfaction of users are also done. The experiment’s result showed the analysis results of the system were almost correct, and users were interested in the idea of this system and we will add more useful functions into the system in the future.
