What is an expert system ICT Igcse?
An expert system is computer software that attempts to act like a human expert on a particular subject area. Expert systems are often used to advise non-experts in situations where a human expert in unavailable (for example it may be too expensive to employ a human expert, or it might be a difficult to reach location).
Is artificial intelligence an expert system?
In artificial intelligence, an expert system is a computer system that emulates the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning through bodies of knowledge, represented mainly as if-then rules rather than through conventional procedural code.
What is a expert system in ICT?
An expert system is a computer program that uses artificial intelligence (AI) technologies to simulate the judgment and behavior of a human or an organization that has expert knowledge and experience in a particular field.
What is the relation between expert systems and artificial intelligence?
AI is the ability of a machine or a computer program to think, work, learn and react like humans. Expert systems represent the most successful demonstration of the capabilities of AI. AI involves the use of methods based on the intelligent behavior of humans to solve complex problems.
What do expert systems do?
Expert Systems An Expert System is a computer program (software) that uses artificial intelligence (AI) to reproduce the judgment of a human with expert knowledge in a particular field. A good Expert System solves a problem accurately, quickly and is easy to use.
Which artificial intelligence technique can be used for the expert system?
November 25, 2020. Backward and forward chaining are methods of reasoning that exist in the Expert System Domain of artificial intelligence. These techniques are used in expert systems such as MYCIN and DENDRAL to generate solutions to real life problems.
What do you mean by expert system?
In artificial intelligence, an expert system is a computer system emulating the decision-making ability of a human expert. The first expert systems were created in the 1970s and then proliferated in the 1980s. Expert systems were among the first truly successful forms of artificial intelligence (AI) software.
What is an expert system what are the characteristics of an expert system?
An expert system operates as an interactive system that responds to questions, asks for clarification, makes recommendations and generally aids the decision making process. Expert system provides expert advice and guidance in a wide variety of activities from computer diagnosis to delicate medical surgery.
What is rule-based expert system in AI?
A rule-based expert system is the simplest form of artificial intelligence and uses prescribed knowledge-based rules to solve a problem 1. The aim of the expert system is to take knowledge from a human expert and convert this into a number of hardcoded rules to apply to the input data.
What are the components of expert system in artificial intelligence?
There are 5 Components of expert systems:
- Knowledge Base.
- Inference Engine.
- Knowledge acquisition and learning module.
- User Interface.
- Explanation module.
How does the expert system in IGCSE work?
The expert system guides the user through a set of questions which are answered by typing in boxes or clicking options. #. The system will suggest a diagnosis and the user can decide if it is serious enough to call a doctor or if the health problem can be solved with a an asprin and rest.
Who is a knowledge engineer in artificial intelligence?
Knowledge Engineer: Knowledge engineer is the person who gathers the knowledge from the domain experts and then codifies that knowledge to the system according to the formalism.
How is knowledge gathered in an expert system?
Experts are interviewed and their knowledge is gathered and put into a knowledge base. Knowledge from human experts is entered into the system and stored. People using the expert system can then question it (query) and access this stored knowledge.
How is inference engine used in artificial intelligence?
It applies inference rules to the knowledge base to derive a conclusion or deduce new information. It helps in deriving an error-free solution of queries asked by the user. With the help of an inference engine, the system extracts the knowledge from the knowledge base.
