The information in the knowledge base can be expressed in several ways.
Which of the following way uses questionnaires to lead the user through a series of choices until a conclusion is reached?

A. B. C. D.A.
Decision tree uses questionnaires to lead the user through a series of choices, until a conclusion is reached.
Flexibility is compromised because the user must answer the questions in an exact sequence.
For CISA Exam you should know below information about Artificial Intelligence and Expert System Artificial intelligence is the study and application of the principles by which: Knowledge is acquired and used - Goals are generated and achieved Information is communicated - Collaboration is achieved - Concepts are formed - Languages are developed - Two main programming languages that have been developed for artificial intelligence are LISP and PROLOG.
Expert system are compromised primary components, called shells, when they are not populated with particular data, and the shells are designed to host new expert system.
Keys to the system is the knowledge base (KB), which contains specific information or fact patterns associated with a particular subject matter and the rule for interpreting these facts.
The KB interface with a database in obtaining data to analyze a particular problem in deriving an expert conclusion.
The information in the KB can be expressed in several ways: Decision Tree " Using questionnaires to lead the user through a series of choices, until a conclusion is reached.
Flexibility is compromised because the user must answer the questions in an exact sequence.
Rule " Expressing declarative knowledge through the use of if-then relationships.
For example, if a patient's body temperature is over 39 degrees Celsius and their pulse is under 60, then they might be suffering from a certain disease.
Semantic nets " Consist of a graph in which the node represent physical or conceptual object and the arcs describe the relationship between the nodes.
Semantic nets resemble a data flow diagram and make use of an inheritance mechanism to prevent duplication of a data.
Additionally, the inference engine shown is a program that uses the KB and determines the most appropriate outcome based on the information supplied by the user.
In addition, an expert system includes the following components Knowledge interface " Allows the expert to enter knowledge into the system without the traditional mediation of a software engineer.
Data Interface " Enables the expert system to collect data from nonhuman sources, such as measurement instruments in a power plant.
The following were incorrect answers: Rule " Expressing declarative knowledge through the use of if-then relationships.
Semantic nets " Semantic nets consist of a graph in which the node represent physical or conceptual object and the arcs describe the relationship between the nodes.
Knowledge interface " Allows the expert to enter knowledge into the system without the traditional mediation of a software engineer.
The answer to the question is A. Decision tree.
A decision tree is a graphical representation of a set of decisions and their possible consequences. Decision trees are commonly used in artificial intelligence and decision analysis to model decision-making processes. In the context of a knowledge base, a decision tree can be used to lead the user through a series of choices until a conclusion is reached.
In a decision tree, each decision point is represented by a node, and each possible outcome is represented by a branch. The user starts at the root node of the tree and follows the branches until a conclusion is reached. At each decision point, the user is presented with a set of choices, and the decision tree guides them through the process of selecting the most appropriate choice based on their responses.
A decision tree can be thought of as a flowchart, where each decision point leads to one or more possible outcomes. Decision trees are useful because they can handle both categorical and continuous data, and they can easily incorporate new data as it becomes available. They are also easy to understand and can be used to communicate complex decision-making processes to non-experts.
In contrast, rules are a way of expressing knowledge in the form of "if-then" statements, where a set of conditions is used to determine a conclusion. Semantic nets are a type of knowledge representation that use nodes and links to represent concepts and their relationships. A knowledge interface is a user interface that allows users to interact with a knowledge base.
