To build your own Java applet or application-based expert systems, download the FREE e2gRuleEngine expert system shell, e2gRuleWriter decision table knowledge base generator or e2gRuleInduction rule induction/data mining software.
Expert systems are often more effective than other computer-based advising methods because they are...
Goal oriented: expert systems deliver answers to very specific questions that represent the goals of the interview: they aren't focused on abstract or theoretical information.
Efficient: requests for new information are based on your earlier responses -- you don't waste time providing irrelevant input.
Adaptive: if you don't know the answers to all of the questions, alternate paths through the knowledge base might allow deduction of sufficient facts to provide useful advice.
Able to deal with uncertainty: expert systems can process your uncertain responses and, by combining several pieces of uncertain information, may still be able to make strong recommendations.
Able to explain their information requests and suggestions: justification for each question you are asked along with a detailed explanation of the reasoning that led to any recommendations is available as you work. You get to see how the expert system used rules from its knowledge base to convert your input into advice. An eXpertise2Go expert system educates you about your problem as it leads you toward a solution.
