Components of Expert Systems:
User Interface
Inference Engine
Knowledge Base
1. User Interface
With the help of a user interface, the expert system interacts with the user, takes queries as an input in a readable format, and passes it to the inference engine. After getting the response from the inference engine, it displays the output to the user. In other words, it is an interface that helps a non-expert user to communicate with the expert system to find a solution.
2. Inference Engine(Rules of Engine)
The inference engine is known as the brain of the expert system as it is the main processing unit of the system. 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.
There are two types of inference engine:
Deterministic Inference engine: The conclusions drawn from this type of inference engine are assumed to be true. It is based on facts and rules.
Probabilistic Inference engine: This type of inference engine contains uncertainty in conclusions, and based on the probability.
3. Knowledge Base
The knowledgebase is a type of storage that stores knowledge acquired from the different experts of the particular domain. It is considered as big storage of knowledge. The more the knowledge base, the more precise will be the Expert System.
It is similar to a database that contains information and rules of a particular domain or subject.
One can also view the knowledge base as collections of objects and their attributes. Such as a Lion is an object and its attributes are it is a mammal, it is not a domestic animal, etc.
Applications of Expert System
In designing and manufacturing domain It can be broadly used for designing and manufacturing physical devices such as camera lenses and automobiles.
In the knowledge domain These systems are primarily used for publishing the relevant knowledge to the users. The two popular ES used for this domain is an advisor and a tax advisor.
In the finance domain In the finance industries, it is used to detect any type of possible fraud, suspicious activity, and advise bankers that if they should provide loans for business or not.
In the diagnosis and troubleshooting of devices In medical diagnosis, the ES system is used, and it was the first area where these systems were used.
Planning and Scheduling The expert systems can also be used for planning and scheduling some particular tasks for achieving the goal of that task.
Hence in this article we have completely discussed the topic Expert Systems.
Now we'll discuss the others.
