10. What is Part-of-Speech (POS) tagging and why is it important in Natural Language Processing (NLP)? Provide a simple sentence and demonstrate its POS tagging.
11. How can Named Entity Recognition (NER) be used for information extraction?
12. Discuss the applications of NLP, focusing on how it leverages morphology, lexicon, syntax, and semantics. Provide real-world examples.
13. Explain Parsing with an example.

Unit 3: Machine Learning

14. Define Machine Learning. Explain its applications.
15. Differentiate between Supervised and Unsupervised learning with examples.
16. Compare and contrast classification and clustering.
17. Explain the concepts of support vectors and margins and how they are used in Support Vector Machines (SVMs) to classify datasets.
18. Explain the four stages of Case-Based Reasoning.
19. Write short notes on:
    • Linear Classifier
    • Nearest Neighbor
    • Decision Tree
    • Random Forest
    • Support Vector Machines (SVM)
    • Neural Networks

Numerical / Problem Type:

19. Given a dataset with features and a class label, use the k-Nearest Neighbor (k-NN) algorithm to classify a new data point. You will be required to calculate the Euclidean distance and determine the class of the new point.

Unit 4: Knowledge Representation and Reasoning

20. Explain propositional logic and its use in knowledge representation. How does it differ from predicate logic?
21. How can predicates be used for knowledge representation and reasoning? Explain with examples.
22. How does probabilistic reasoning handle uncertainty in knowledge representation?
23. Write a short note on Description Logic.
24. Explain Knowledge Representation Languages.
25. What is Non-Monotonic Reasoning?

Unit 5: Ontology Engineering

26. What is an ontology? How can it be used in knowledge engineering?
27. Explain the Classifications of Ontology.
28. Methodologies used in Ontology Engineering.
29. Compare and contrast the concepts of ontology and language in the context of Knowledge Engineering. How does each contribute to representing and sharing knowledge?
30. Describe the role of Web Ontology Language (OWL) in ontology engineering. How does it support the creation and use of ontologies?

Unit 6: Knowledge Sharing

31. Discuss the concept of the Semantic Web and its significance. What are the major challenges associated with it?
32. What are RDF (Resource Description Framework) and linked data? Explain how RDF facilitates the creation and use of linked data.
33. Illustrate your answer with examples of practical applications where Semantic Web technologies, RDF, and Linked Data are effectively utilized.
34. What are the principles of linked data?
35. Explain Description Logic with an example.
36. What is the Social Web? How does it contribute to knowledge sharing?

Numerical / Problem-Oriented Question Types

1. k-Nearest Neighbor (KNN) – classify a new data point using Euclidean distance.
2. Support Vector Machine (SVM) – explain support vectors and margins with dataset examples.
3. Probabilistic Reasoning – small problems on uncertainty representation.
