For instance, Amazon’s Alexa Price in 2017 included several different universities all competing to create the most conversant chat bot. That is because these systems try to solve problems in a straightforward manner. The expert systems are capable of a number of actions including: Components/ Architecture of Expert Systems. PXDES: This system could easily determine the type and the degree of lung cancer in patients based on limited data. It applies inference rules to the knowledge base to derive a conclusion or deduce new information. MYCIN: This was one of the earliest expert systems that was based on backward chaining. It was initially introduced by researchers at Stanford University and were developed to solve complex problems in a particular domain. Backward chaining is used by an expert system to answer the question “Why did this happen?”. Controlling physical processes based on monitoring. The KB of the MYCIN is updated successfully. The system helps in decision making for compsex problems using both facts and heuristics like a human expert. Tools, as an ES technology, assists in reducing the effort and cost involved in developing an expert system to a large extent. Inference engines also have explanationatory and debugging abilities. Depending upon what has already occurred, the inference engine tries to identify the conditions that could have happened in the past to trigger the final result. The expert system is a part of AI, and the first ES was developed in the year 1970, which was the first successful approach of artificial intelligence. The response of the expert system may get wrong if the knowledge base contains the wrong information.
