Case Manager

QGeNIe includes a Case Manager window that allows users to save a partial or a complete session as a case and retrieve this case at a later time. Cases are saved alongside the model, so when the model is loaded at a later time, all cases are going to be available. Case Manager window can be opened through the View Menu:

Case Manager window looks initially as follows:

case_manager_empty

Adding cases to the Case Manager

Let us add to the Case Manager the three cases analyzed in the Building a qualitative Bayesian network section of this manual. The first case involved failure of climate control on a cold day. Once the evidence in the model has been set, we click on the Add new case button (add_case_icon). This results in the following dialog, which allows for entering case details.

case_manager_new_case_dialog

Once we click OK, the case is visible in the Case Manager:

case_manager

Adding two remaining cases to the Case Manager will result in the following window.

case_manager_multi

The Case Manager window shows the currently applied case with a grayed background.

The Show only evidence nodes button (show_only_evidence_button) reduces the number of columns displayed to those only that have any observations at all. The Apply case (apply_case_button) button allows for transferring a case to the Graph View window. The Delete case button (delete_case_button) removes the current case from the Case Manager. The Update applied case with network evidence (update_case_button) button transfers the current set of evidence from the current model to the current case.

Exporting case records to a data file

Currently, QGeNIe does not allow to export cases from a model to a data file. However, it is possible to retrieve cases using any text editor from the model file (.qdsl). To locate the case descriptions, please search for the tag <cases> in the XML model file.
