Components and Functions of Expert Systems

The video tutorial provides an overview of expert systems, focusing on their purpose and components. It explains the four main components: knowledge base, database of facts, inference engine, and explanation mechanism. The knowledge base consists of rules derived from expert knowledge, while the database of facts contains data relevant to specific situations. The inference engine processes this information to reach conclusions, and the explanation mechanism clarifies the reasoning behind decisions. The user interface allows interaction with the system, facilitating data entry and retrieval.

What is the primary goal of an expert system?

• To perform complex calculations

• To store large amounts of data

• To replace human experts entirely

• To mimic human expertise electronically

Which of the following is NOT one of the four main components of an expert system?

• User Interface

• Knowledge Base

• Database of Facts

• Inference Engine

What is the role of the Knowledge Base in an expert system?

• To store current situational data

• To process and analyze data

• To interact with users

• To provide a set of rules and guidelines

How does the Database of Facts differ from the Knowledge Base?

• It is fixed and unchanging

• It processes data to reach conclusions

• It stores data about the current situation

• It contains rules and guidelines

What is the role of a Knowledge Engineer?

• To design the user interface

• To convert human expertise into a computer-readable format

• To gather data about the current situation

• To process data and reach conclusions

What is the primary function of the Inference Engine?

• To provide explanations for decisions

• To process data and reach conclusions

• To gather data about the current situation

• To store rules and guidelines

Why is the Explanation Mechanism important in an expert system?

• It stores all the rules and guidelines

• It provides clarity on how decisions are made

• It gathers data about the current situation

• It processes data to reach conclusions

Which component of an expert system is responsible for interacting with users?

• Knowledge Base

• Database of Facts

• Inference Engine

• User Interface

How does the User Interface affect the experience of using an expert system?

• It influences how users input and receive data

• It affects how data is processed

• It determines the rules and guidelines used

• It stores data about the current situation

What is the significance of the User Interface in an expert system?

• It stores current situational data

• It allows users to interact with the system

• It provides a set of rules and guidelines

• It processes and analyzes data
