Proposal for Data Analysis Tool PADOC by Data Integration and Visualization

Abstract

In Analects, there is a saying "visiting old, learn new". This means to investigate old things, in order to obtain new knowledge and insights.The process of data analysis could be interpreted as an act to analyze the data of the past, discover new knowledge and insights mathematically and make good use of them toward better future. Until end of the 20th century data was very valuable and less reliable, but now the accumulation of data became remarkable due to the explosive spread of the Internet society in recent years. However, proper use of data has not yet been established. The reason for this is that since the data is accumulated according to the operation of each business, there is no standardized analytical method because the accumulation state of data varies. Therefore, it is necessary to edit and integrate data by processing on computer for analytical purpose. Furthermore, it is necessary to examine whether the edited data is appropriate for analysis. To do so, it is convenient to have a tool that analyzes data while visually showing and checking data by editing and examining data. This paper proposes a graphical analysis integration environment "PADOC" to facilitate data editing and data review
