Information systems are always developing and improving in a profitable way business and everyday applications. The word expert system, or commonly called an expert system, is one of the most successful trends today.
In fact, the main purpose of making information systems is to simplify and streamline human work.
Expert systems and their implementation will be discussed in detail on this occasion. As defined, this kind of system has some advantages and disadvantages which we will discuss in more detail below.
What are Expert System Components
First of all, we will talk about what an expert system is. The general definition of an "expert system" is a computer program or information system that uses the knowledge of one or more experts in a particular field.
The targeted expert is someone who has unique expertise in their respective profession, for example doctors, psychologists, mechanics, and so on. The software was originally designed by researchers in artificial intelligence (AI) programs in the 1960s and 1970s and was only put into use in the 1980s.
Purpose of the Expert System Component
Expert systems have the capacity to propose a series of activities or user behavior to be able to operate a precise and accurate corrective system. In terms of drawing conclusions based on existing data and facts, this system utilizes the ability of reasoning processes.
The following are some of the main objectives of using an expert system:
An expert system attempts to produce an assessment or description of a collection of raw data (raw data). Decision making is based on observation results, starting from image analysis, speech recognition, signal interpretation, and so on.
Have the ability to predict the outcome of certain circumstances and events, such as demographic, economic, financial and other data,
can find fault sources in complex scenarios based on observed symptoms with accurate diagnosis.
Design Design Expert System Components
able to find and develop configurations related to system components that are suitable for certain performance goals by meeting certain limits. Plans of buildings, fields, and so on are good examples.
With the help of an expert system, a series of steps can be planned to achieve a certain goal at a certain time.
The implementation process is an example of a computer-assisted monitoring system, which involves anticipated state based observations (CAMS).
We can identify and analyze potential causes of system failures and malfunctions.
recognize the degree to which you lack knowledge about the subject
Have the knowledge to regulate complex environmental behavior patterns (environment). To illustrate, consider the concepts of interpretation control, improvement control, and prediction prediction (estimate).
Methods in the Expert System
There are various approaches used in using expert systems, including the following.
AHP (Analytical Hierarchy Process)
AHP is a technique that uses an expert system to compare many pairs of criteria and make judgments based on the results of these comparisons.
Variables are used to study programs hierarchically based on sequence for the program analysis approach. Then, it will be compared with existing metrics to draw conclusions about the value of each criterion and variable used.
Breadth First Search
Breadth-first search is an algorithm that functions to search extensively for data on an expert system. In this procedure, previously checked information is stored in the data queue process (queue).
In addition, a boolean table is also needed to store information in a node so that no information is viewed more than once.
BFS (Best First Search)
Combining DFS with a "breadth-first" approach is the best way to start the search, because the expert system can display the results of the variable analysis that has been carried out.
DFS (Depth First Search)
Expert systems are also used in the DFS approach. The algorithm relies on a tree or graph structure and data depth.
Forward Tracing (Forward Chaining)
It is a reasoning strategy that is incorporated into an expert system, which begins with a fact-finding procedure. Where the data is used to weigh the importance of a truth to the resulting hypothesis
Backward chaining is the opposite of forward chaining, where this approach monitors the decision system starting from the conclusion drawing stage at the point of reasoning. The next step is to come up with hypotheses and test them until you have enough information to draw a solid conclusion.
The structure used in the Expert System Component
An expert system consists of various components and structures that work together to create a complete information system. The following are some of the components that make up this system architecture.
User Interface (User Interface)
Interface or interface is a technique used as a way to communicate and engage with people (users) (users). The interface gets information from the user and turns it into commands that the system can understand.
An understanding of problem solving formulations and techniques is included in the knowledge base. For a computer system to solve problems, knowledge must be acquired through accumulation, transformation, and transfer of capabilities.
The job of an engineer at this point is to collect all available information and store it in a central repository (insights).
Acquisition of knowledge is the process of accumulation, transformation and transfer of any skills for solving problems from a source of knowledge into a computer system.
In this phase, the engineer's job is to absorb all the knowledge to be sent to the knowledge base (Insight).
Inference Engine (Inference Engine or Motor)
This component provides a method of thinking and mentality used by experts to be able to solve a problem well.
An inference engine is a piece of computer software that gives you methods to use at work and then analyzes the results to give you suggestions.
Workplace / Blackboard
Workspace is a working memory collection area that is used to record every event that occurs, including momentary decision making.
Annotation facilities are incorporated as an additional component to promote the use of expert systems and monitor the reactions and results of interactive explanations of behavior in expert systems.
Experts also have superior analytical skills to be able to improve their performance in such a way. This aptitude consists of proficiency in computerized learning. As a result, the algorithm is able to distinguish between past successes and failures based on data that will be useful in the future.
An example of an Expert System
The following are some examples of programs that implement expert systems, namely:
- Dendral is an application for determining the molecular composition of new chemical mixtures that have never been tested before.
- MYCIN is software designed to diagnose a wide variety of disorders.
- Prospector is an application adapted to the demands in the field of geology.
- XCON and XSEL are tools used to manage large computer systems.
Advantages of Expert Systems
The next thing that will be discussed is how to present information about the benefits of an expert system.
- Work more efficiently to get more done in less time.
- They have the ability to improve the quality of their advice by being more consistent.
- It has a high degree of dependability and capacity to operate in real time.
Disadvantages of Expert Systems
The weaknesses of the expert system are as follows:
- There is a barrier to gaining new experience or understanding by adopting different ways held by many experts.
- It costs a lot of money to train professionals, but the end result is worth it if the information they produce is of high quality.
- The level of expert system judgment does not always produce absolute truth. Still need frequent testing stages to be able to make the best decision.
