Given the generated sentence displayed in Figure 7.2, the user might wish to remove the explicit reference to the agent of the action. By clicking the mouse pointer on the AGENTOVERTNESS box in the summary table, the AGENTOVERTNESS choice system will be re-entered and the Agent Overtness menu shown in Figure 7.3 will be presented.
If the user selects covertagent instead of overtagent, no further choices are required in the network traversal, so the realization procedures will immediately generate the revised sentence. It will be displayed with its summary table, as shown in Figure 7.4.
After the new sentence is displayed, another feature may be revised. If the user clicks on SUBJECTTHEME in the new summary table, the SUBJECTTHEME system will be entered and the Subject Theme menu shown in Figure 7.5 will be presented.
If the user now selects agentStheme instead of affectedStheme, another revised version of the sentence will be generated, as shown in Figure 7.6. This revision loop may be repeated as often as desired.
