Knowledge Engineering is a multidisciplinary field within artificial intelligence that focuses on the acquisition, representation, and utilization of human expertise to build intelligent systems. It involves systematically gathering domain-specific knowledge from experts, encoding it into a structured format—such as rules, ontologies, or knowledge graphs—and integrating it into software applications. This process enables machines to mimic human reasoning, solve complex problems, and make informed decisions in areas like medical diagnosis, financial forecasting, and automated troubleshooting. By bridging the gap between human cognition and computer processing, Knowledge Engineering enhances the capabilities of expert systems, supports decision-making, and drives advancements in fields such as natural language processing, robotics, and data analytics. Its iterative nature ensures that knowledge bases evolve, adapting to new information and improving accuracy over time.

A. A system that uses neural networks
B. A system that applies if-then rules to make decisions
C. A system for graphical user interfaces
D. A system for data encryption
Answer: B
Explanation: Rule-based systems use predefined rules (e.g., IF condition THEN action) to encode knowledge and perform inference.
6. Which tool is often used in Knowledge Engineering for building expert systems?
A. Microsoft Word
B. Protégé
C. Adobe Photoshop
D. Excel spreadsheets
Answer: B
Explanation: Protégé is an open-source tool specifically designed for creating and managing ontologies and knowledge bases.
7. What does inference mean in the context of Knowledge Engineering?
A. Storing data in a database
B. Deriving new knowledge from existing knowledge
C. Designing algorithms
D. Inputting data into a system
Answer: B
Explanation: Inference involves logical processes, such as deduction or induction, to draw conclusions from the knowledge represented in a system.
8. Which knowledge representation technique uses frames to organize information?
A. Decision trees
B. Logic programming
C. Frames
D. Bayesian networks
Answer: C
Explanation: Frames represent knowledge as structured templates with slots for attributes, making it easier to model real-world objects and their properties.
9. What is the main challenge in Knowledge Engineering related to experts?
A. Hardware limitations
B. Knowledge elicitation difficulties
C. Software updates
D. Network connectivity
Answer: B
Explanation: Eliciting accurate and complete knowledge from human experts can be challenging due to issues like incomplete recall or communication barriers.

C. It designs the user interface
D. It collects data from users
Answer: B
Explanation: The inference engine processes the rules and facts in the knowledge base to perform reasoning and generate solutions.
11. Which of the following is an example of declarative knowledge in Knowledge Engineering?
A. How to ride a bike
B. Facts about historical events
C. Procedural code for sorting algorithms
D. User commands in a program
Answer: B
Explanation: Declarative knowledge involves static facts and information, such as “Paris is the capital of France,” rather than processes.
