A Functional Model for Data Analysis and Result Visualization
Nicolas Spyratos, Е.С. Симоненко, Tsuyoshi Sugibuchi · Journal of the Association for Information Systems · 2009
In several Web based applications (e-commerce, e- learning, digital libraries, etc.) one needs to display a dense array of information in a small amount of space (such as a screen) in a manner that communicates clearly and immediately. The information displayed is usually aggregates of results obtained through analysis of large amounts of data. We present a functional model that supports the data analysis and aggregation process, and a prototype that supports casual users in doing the following: (a) construct an analytic query visually, in an interactive manner, (b) visualize the aggregate result in a user selected mode (histogram, pie, etc.), (c) explore the query result by providing equivalent representations at different aggregation levels or for different parameter values selected by the user.
