Read the answers carefuly and select all options which covers expert system functionality

Human expert enter all the facts and rules in knowledge base time to time .normal user using interface answer multipule questions drived by explanation system .answers are taken in inferece engine for possible matches based on forward and backword chaining .if any further question and answering is required explanations system display it on screen using user interface.if any new facts or information which is not avaiable in knowledge based is finded through knowledge base editor it is interted in KBS

User enter information through user interface and taken into explanation system to be stored as facts and when users ask for facts its will be drived by inference engine to display on screen where as when ever user needs any knowledge it will be obtained from knowledge editor

None of above

The correct answer states that in a Plant identification expert system, a human expert enters all the facts and rules into the knowledge base. A normal user interacts with the system through an interface and answers multiple questions generated by the explanation system. The answers are then processed by the inference engine using forward and backward chaining to find possible matches. If further questions are required, the explanation system displays them on the screen. Any new facts or information that are not available in the knowledge base can be added through the knowledge base editor.

Boring in usage no new task in it

Expert system follow rules these dont have common sense like humans

The answer correctly identifies three disadvantages of using expert systems. The first disadvantage is that human experts have a wide range of sensory experience, which allows them to gather information from various sources, while expert systems are currently dependent on symbolic input, limiting their ability to gather sensory information. The second disadvantage is that human experts can automatically adapt to changing environments, whereas expert systems need to be updated manually. The third disadvantage is that expert systems follow rules and lack common sense, unlike humans who can apply their intuition and judgment in decision-making.
