Expert system - An Example (Whale Watcher)

Although your students may not be avid whale watchers, this example of a rule based system is worth looking at.

Get them to enter details of their 'imaginary' whale, and after answering all of the questions, they should have an identification of the whale that they 'saw'!

Expert system - Medical Diagnosis

This is a superb example of an expert or rule based system. As you give answers to one question, it uses your answers to present you with the next set of questions.

The downside is that you can't actually get your medical diagnosis at the end without paying! However, it is well worth students having a look at in order to see how an expert system works.

They need to choose 'new user' -(there is no charge for working your way right through the system - just don't expect to get a final diagnosis).
