A Case-Based Data Mining Platform - Data Mining: Theory, Methodology, Techniques, and Applications - page 35

4.2 User Interface
The main user interface of this platform is illustrated as Figure 4. Here, the main
user interface is the one of case builder, while the other four functional models are
dialog-based interface. On its upper part, we can see there are three functional sub-
windows. From left to right, and from top to bottom, the three windows respectively
are case management window, case exploring window, and similar case
management window. Coupled with these three windows, there are three tabbed
windows. As shown in the lower part, they are respectively operator management
window, case building window, and message window. Thus, there are totally six
functional windows.
The case management window is used to organize the cases. The cases can be
grouped from different aspects, such as, industry type, business objective, data
mining goal, as well as company name and department name. The operator
management window is used to organize and register operators. The operators can
be the data mining libraries from third parts. The case exploring window is used to
explore the case's content in detail. The case will be displayed with graphical flow
in case exploring window. The user can view these aspects, such as, what data have
been used, what operators have been involved, and what model(s) has been
generated. The case building window is used to build the new case. Besides
exploring a concrete case, we can modify the processing flow or build a new
processing flow from scratch in case building window. The similar case
management window is used to manage the similar cases. We assume we can get
more than one similar case at similar case retrieval. The similar case management
window is used to navigate all the similar cases to view. Meanwhile, there is a
threshold to set the criterion of similarity and control the number of retrieved
similar cases. The last window is the message window, which is used to log the
messages generated in the data mining process.
These six windows can communicate one and another. For example, from the case
management window, we can select a specific case to explore its content in case
exploring window, to retrieve its similar cases and display in similar case management
window, or to be used as template to modify in case building window. From the similar
case management window, we can select a specific case to explore in the case exploring
window or modify in the case building window.
4.3 Application Scenario
Basically, the application scenarios of this platform include case exploring, model
building, and model deployment. Among them, the model building is the main
application scenario and will be explained here. As shown in figure 5, the activity
diagram of model building is illustrated. Suppose a new data mining case is needed to
conduct on this platform, the user needs to do the steps:
1. Click “ Retrieve Similar Case ” button, which is located at the bottom of case
management window, to open “ Case Retriever ” dialog.
