- cDiscuss strategies for handling ambiguity in parsing. 2
- dHow Dynamic Programming is emp loyed in parsing algorithms? 2
- eDiscuss the limitations of supervised approaches in handling W SD challenges
- fHow do semantic attachments cont ribute to disambiguating word senses? 2
- gDiscuss the applications of filter bank methods in speech sign al processing. 2
- hHow do filter banks contribute to speech analysis? 2 i. Describe the role of Perceptual Linear Prediction. 2 j. How does the process of feature extraction contribute to under standing speech patterns?
Section BAttempt any three o f t h e f o l l o w i n g : 10 x 3= 30
- aProvide an overview of Hidden Markov Models and Maximum Entr opy models in word-level analysis. How do these models contribute to language processing tasks, and what are their strengths and weaknesses?
- bDiscuss Probabilistic CYK parsing and Probabilistic Lexicali zed CFGs. How do these probabilistic parsing techniques improve upon trad itional parsing algorithms, and what are their applications in natural language processing?
- cCompare and contrast first-order logic with propositional lo gic. Discuss the expressive power of first-orde r logic and its significance in r epresenting complex relationships
- dAnalyze the challenges associated with accurately representi ng and classifying speech sounds. How do these challenges impact the development of speech recognition systems?
- eExplain the significance of Li kelihood Distortions in speech analysis and how they contribute to the assessment of speech models. How does the process of feature extraction contribute to understanding speech patterns?
Section CAttempt any one p a r t o f t h e f o l l o w i n g : 10 x 1= 10
- aExplain the concept of Minimum Edit Distance and its signifi cance in the context of word-level analysis. Provide examples to illustrate its application
- bWhat are N-grams, and how are u nsmoothed N-grams used in lan guage modeling? Discuss the challenges associated with evaluating N-g rams and the role of smoothing techniques
- aCompare and contrast Dependency Grammar with Phrase Structur e Grammar. Highlight the key differences in representing syntacti c relationships between words in these two grammatical frameworks
- bDelve into the concept of Shallow Parsing and its applicatio ns. How does Shallow Parsing differ from deep parsing, and what are the adva ntages and limitations of each approach?
- aExamine how thesaurus-based and distributional methods contr ibute to measuring word similarity. Discuss the strengths and weaknesses of each approach and their applicability in different contexts
- bCompare and contrast WSD tec hniques using dictionaries and thesauri. How do these lexical resources contribute to disambiguating word se nses, and what are the considerations when choosing between them?
- aExplore the acoustic phonetics aspect of speech production. How do the acoustics of speech production contribute to the perceptual dif ferences between various speech sounds?
- bExplore the Linear Predictive Coding method in speech proces sing. How does LPC model speech signals, and what are its advantages in s peech analysis and synthesis?
- aElaborate on the concept of time alignment in speech analysi s, focusing on the techniques of Dynamic Time Warping and the representation of multiple time-alignment paths
- bExplain the process of evaluating Hidden Markov Models, incl uding the concept of the Optimal State Sequence and the role of Viterbi S earch in determining the most likely sequence of states
