What This Course Covers

Foundations of NLP

• Tokenization: splitting raw text into meaningful units.
• Stemming vs. Lemmatization: choosing appropriate morphological reduction.
• Part‑of‑Speech (POS) Tagging: assigning grammatical categories to tokens.
• Named Entity Recognition (NER): detecting people, organizations, and locations.

Text Representation and Feature Engineering

• Bag‑of‑Words model: representing documents as word count vectors.
• TF‑IDF: weighting terms based on frequency and inverse document frequency.
• Word2Vec and GloVe: learning dense vector representations from large corpora.
• Document embeddings: generating vectors for whole texts using Doc2Vec.

NLP Models and Algorithms

• Naive Bayes Classifier: probabilistic approach for text classification.
• Support Vector Machines (SVM): margin‑based classification for sentiment analysis.
• Hidden Markov Models (HMM) and Conditional Random Fields (CRF): sequence labeling techniques.
• Transformer models: leveraging BERT and GPT for language understanding and generation.

Syntax and Parsing

• Context‑Free Grammars (CFG): formal rules for generating syntactically valid sentences.
• Dependency parsing: extracting grammatical relationships between words.
• Constituency parsing: breaking sentences into hierarchical phrase structures.
• Transition‑based vs. graph‑based parsing: comparing algorithmic strategies for syntactic analysis.

Semantic Analysis

• Semantic Role Labeling (SRL): identifying predicate‑argument structures.
• Word Sense Disambiguation (WSD): resolving ambiguous word meanings using context.
• Semantic similarity measures: quantifying likeness between words or sentences.
• Sentiment analysis: classifying text polarity from positive to negative.

Applications and Advanced Topics

• Machine translation: translating text across languages with neural models.
• Text summarization: generating concise abstracts from long documents.
• Question‑answering systems: building models that retrieve precise answers from corpora.
• Ethical considerations: addressing bias, privacy, and fairness in NLP deployments.
