What was the first expert system
The system generally regarded as being the first expert system was DENDRAL which was built in 1971 by Edward Feigenbaum at Stanford University.
It was sponsored by NASA and was a classification expert system for their use on an unmanned space probe..
What is the difference between AI and expert system
An expert system is an AI software that uses knowledge stored in a knowledge base to solve problems that would usually require a human expert thus preserving a human expert’s knowledge in its knowledge base. … AI involves the use of methods based on the intelligent behavior of humans to solve complex problems.
What are the limitations of expert system
Limitations of Expert SystemThe response of the expert system may get wrong if the knowledge base contains the wrong information.Like a human being, it cannot produce a creative output for different scenarios.Its maintenance and development costs are very high.Knowledge acquisition for designing is much difficult.More items…

How do expert systems work
An expert system is made up of three parts: A user interface – This is the system that allows a non-expert user to query (question) the expert system, and to receive advice. The user-interface is designed to be a simple to use as possible. A knowledge base – This is a collection of facts and rules.
What are the main components of expert systems
An expert system generally consists of four components: a knowledge base, the search or inference system, a knowledge acquisition system, and the user interface or communication system. Knowledge systems solve difficult problems of the real woorld by performing inference processes on explicitly stated knowledge.
What are the main goals of AI
The goals of artificial intelligence include learning, reasoning, and perception. AI is being used across different industries including finance and healthcare. Weak AI tends to be simple and single-task oriented, while strong AI carries on tasks that are more complex and human-like.
What are the types of expert system
There are mainly five types of expert systems. They are rule based expert system, frame based expert system, fuzzy expert system, neural expert system and neuro-fuzzy expert system. We discussed the expert systems based on their knowledge representation, inference engine, working of the system and user interface.
What is expert system with example
An expert system is an example of a knowledge-based system. Expert systems were the first commercial systems to use a knowledge-based architecture. A knowledge-based system is essentially composed of two sub-systems: the knowledge base and the inference engine.
