FREE online courses on Expert Systems - User Interface
The acceptability of an expert system depends to a great
extent on the quality of the user interface. The easiest to implement interfaces
communicate with the user through a scrolling dialog as illustrated in figure
1.4. The user can enter commands, and respond to questions. The system responds
to commands, and asks questions during the inferencing process.
More advanced interfaces make heavy use of pop-up menus,
windows, mice, and similar techniques as shown in figure 1.5. If the machine
supports it, graphics can also be a powerful tool for communicating with the
user. This is especially true for the development interface which is used by the
knowledge engineer in building the system.
