The stub concept is the primary organizer of user-highlighted samples.
To add a stub concept:
In the Ana Tab, select the pass in the analyzer sequence where you want the automatically generated rules to be inserted.
In the Gram Tab, right click and select Add > Stub.
Give the stub concept a name in the dialog box.
Click OK to finish adding the stub concept.
Note:
The newly added stub concept is added to the analyzer sequence in the Ana Tab as a stub region. The stub region is indicated by stub_name and ends with end_name.
You can add a stub region directly to the Ana Tab by highlighting the pass where you want the region to be inserted, right-clicking and selecting Add > Stub from the context menu. The stub concept is added to the Gram Tab.
