AI - The art and science of making computers do interesting things
that are not in their nature.
Interactive Web-Based Experts
Like all computer programs, expert systems take input, process it, and provide
output. For example, an expert system might input symptoms and output a diagnosis;
input customer requirements and output a product configuration; or input a robot's
situation and output an action.
In many cases the required inputs can be gathered beforehand and sent to the
expert system, which then processes the input and produces the output. This
might be the case in a telephone pricing module, where the facts of a particular
call are known and input to the system that then applies the correct rules to
determine the price for that call.
Interactive Dialogs
However, one of the fascinating things about the behavior of rule-based expert
systems is the way they can selectively and interactively gather only the data
needed for a particular answer. This features gives them a more human-like quality
justifying a bit the broad label of artificial intelligence.
Consider, for example, these rules to help with video monitor problems that
might be part of a computer technical support system:
if screen is blank and led light is on, then move the mouse.<>
