近幾年來資料採礦及雲端運算的興起，導致許多公司企業紛紛推出有關雲端運算的服務，或利用資料採礦的技術以助於了解客戶行為。而資料採礦的技術不僅是企業所獨享的一個工具，一般非企業的使用者也常常會面臨到決策問題，為了讓一般使用者能夠方便取得軟體工具以及節省時間成本，本研究以雲端運算為概念，利用RExcel軟體和Excel VBA程式語言為研究工具，發展出一個資料採礦分類雲端運算系統。
本研究將欲分類的目標變數分為三種型態：數字連續型、數字類別型以及文字類別型，此分類系統會依照目標變數型態的不同，而採取不同的分類模型來分析使用者之資料，並分別以三個資料檔為例，上傳至此資料採礦之分類系統進行分析後，其分析結果報表將以網頁預覽的方式呈現給使用者，使用者可以針對連續型目標變數的資料分析結果，利用MAPE值評估分類模型之優劣，而類別型目標變數的資料分析結果，則可以正確率來評估分類模型之優劣。
使用者可透過簡易步驟來操作此系統，並選擇可解釋資料之最佳模型，也可從結果報表中獲取資料之特性，更進一步地可以進行所需的決策。
關鍵字：雲端運算、資料採礦、分類模型 / In resent years, the rise of data mining and cloud computing has led many enterprises have been offering services related to cloud computing, or using data mining techniques to understand customer behaviors. Data mining is a tool not only for enterprises, but also for general non-business users who often face making decisions. In order to enable general users to easily assess the software and save time and costs, this study proposes a classification system of data mining constructed by RExcel and Excel VBA, which is based on cloud computing.
In this study, the target variable is divided into three types: digital continuous, digital categorical and literal categorical. The classification system is in accordance with the different types of target variables, taking different classification models to analyze user’s data. Taking three data as examples, respectively, uploading them to the system, then the analysis results will be present to the user in the way of page preview. The user can use MAPE values to evaluate classification models with regard to the results of the data for the continuous target variable, and use correct rate to evaluate classification models with regard to the results of the data for the categorical target variable.
Users can take simple steps to operate the system, select the best model which can explain the data, and obtain the characteristics of the data from the result reports, further to the necessary decision-making.
